CULT+MATH LLC is an independent strategy firm working with brands worldwide,
from Houston, Texas. It was founded by Ipalibo Da-Wariboko. The practice works on value creation, defined technically as the gap
between willingness to pay and willingness to sell, and on the decisions that
widen it.

## Decision Briefs

Each brief covers six decisions one executive seat signs, names the seat that owns each and
the seat that contests it, sources and dates every figure, and says where a number could not
be sourced. $495, PDF delivered on payment, 14-day refund guarantee (one per organization).

- Paid runs, paid by the agent's own wallet over MPP (HTTP 402, Stripe shared payment
  tokens) or, where the 402 offers it, x402 (USDC on Base), no checkout page: run_filing_trend quotes a fresh, citable measurement of what
  share of U.S. 10-K filers mention a phrase, year by year, from SEC EDGAR, with a
  denominator control, a null control that must be 0, the stated limits, a run id and a
  dated citation line. It returns the payment URL, https://cultmath.com/run/filing-trend.
  A run that fails its controls is not charged. Discovery: https://cultmath.com/openapi.json
  run_regulatory_trend does the same for U.S. federal final and proposed rules, from the
  Federal Register, optionally for one agency (https://cultmath.com/run/regulatory-trend).
  Also: run_spend_trend (federal contract spending, USAspending), run_triangulation (one
  phrase in filings, rules and spending at once), run_peer_benchmark (a company's filed
  metric against its peers, SEC XBRL) and run_ai_visibility (whether a domain is cited
  when four AI assistants answer a question, whether that holds across three askings, and
  whether each flagship model agrees), run_disclosure_check (has any company, or which
  named peers, started reporting a figure, with the SEC filings linked) and
  run_regulatory_clock (U.S. federal documents on a topic open for comment, and rules about to
  take effect) and run_deal_activity (whether M&A in a sector is rising or falling, from 8-K
  merger agreements, and who is doing it), run_demand_check (whether search demand for a category
  is rising beyond the market, confirmed against SEC filings) and run_answer_share (which domains
  AI assistants cite across a category's buyer questions, and whether that holds),
  run_share_of_search (who is gaining share of search among named brands), run_premium_check
  (whether a brand's buyers are hunting for a cheaper way in) and run_angle_demand (which reason
  to buy people search for in a category, and which is growing), run_channel_mix (where buyers land
  when they search: retailers, reviews and media, brand sites or forums), run_claim_check (whether
  competitors' home pages already make a claim, and who added it this year) and run_fad_check
  (whether a moment is lasting or past its peak, on search and Wikipedia against controls). Each run's tool says whether it is switched on.

## Core definitions

- **Value created** — the gap between what customers are willing to pay and what
  suppliers and employees are willing to accept, widened. Everyone in the
  transaction is better off.
- **Value captured** — the same gap, redistributed. One party takes more of what
  already exists. It reads as growth in a quarter and compounds to nothing.
- **Willingness to pay (WTP)** — the most a customer would pay before walking
  away. Raising it is the only durable source of margin.
- **Willingness to sell (WTS)** — the least a supplier or employee would accept.
  Lowering it without coercion is the other half of value creation.
- **Narrative design** — the method beneath the outcome: building a reason to
  choose, which is what moves willingness to pay.

## What the practice sells

Six deliverables. An engagement produces one or more, depending on the decision:

- Brand positioning and messaging — A written positioning statement, the reason-to-believe behind it, and a messaging framework your team and agencies can actually use — by audience, by channel, by stage of the buying journey.
- Competitive and category analysis — A structural read of your category: who you actually compete with, where the money is, what holds a premium, and where the opening is. Built from primary sources with the limits of the research stated.
- Audience segmentation and personas — Segments built from behavioral evidence rather than demographics, with the purchase drivers and barriers for each, and what to do differently for the ones that matter.
- Go-to-market strategy — Target customer, channel choices, pricing logic, launch sequence, and the measures that tell you whether it worked.
- Creative and campaign briefs — Briefs that give creative teams something to build on — a real insight, a clear job to be done, and a defined measure of success.
- Pricing and willingness-to-pay analysis — What your customers will pay — measured, not assumed — which half of your premium is copyable and which is not, and what would have to be true to charge more.

## How the work is built

CULT+MATH runs on the ADMADS Engine, the evidence system it built in-house:
- Sourced and dated. Public filings, market and economic data — each figure with its source, its date and a link to the original.
- Your customers, counted. Interviews, surveys and reviews coded and counted by segment, so a pattern is a pattern and not an anecdote.
- Limits stated. Every evidence pack says which conclusions it supports, which are only directional, and which it cannot support.

It gathers and counts; the judgment is the practice's.

## Stated limits

- Willingness-to-pay work is slower than value-capture work. It does not change
  the current quarter's number.
- Go-to-market cannot rescue a product that does not work.
- The practice sells judgment, not execution capacity.

## Published research

Standing studies are indexed at https://cultmath.com/research. Each one registers its
question and its falsifier before any data is pulled, publishes every row rather than a
summary, states its limits on the page, and is re-run on a stated schedule with
corrections published in place and dated.

### Nobody stopped caring. They stopped buying. (October 26, 2026)
https://cultmath.com/research/cpg/halloween-candy

A standing study by Ipalibo Da-Wariboko of Halloween candy demand against Halloween
candy sales. Re-run as soon as October closes. Registered question, bands and falsifiers
written before any data was pulled.

- **The occasion is at a six-year high and the basket is not.** September 2026 searches
  for "when is halloween" ran 35.7% above the term's own 2019-2024 September average and
  "halloween candy" 15.5% above, while NielsenIQ reported candy sales down 6.7% in the
  month to October 17 and down 11.7% in mid-September.
- **What fell is the discretionary spend around the occasion.** Decorations are down
  58.6% against their own six-year September average, costumes 36.4%. The further a
  category sits from the ritual itself, the harder it was cut. Candy is cut last.
- **Nobody is talking about not going.** Across 409 comments about trick-or-treating,
  with five terms registered before the pull, "fewer" and "skipping" each appeared zero
  times. Only small bags grew this season; large and extra-large fell hardest.
- **The price anxiety is specific to this category, and a control measures it.** Five
  price words appear in 17.51% of 531 comments about Halloween candy and 0.65% of 307
  comments about Halloween costumes - same holiday, same week, same five words, a factor
  of 27 apart.
- **The price lever is spent in both directions.** Candy and gum prices rose 44% over
  five years against 22.5% for all food at home, and gross margin still fell: Hershey
  45.4% to 33.5%, Mondelez 40.0% to 28.4%. Meanwhile non-chocolate candy came down about
  3% a pound this season and sales did not rise. The page states the caveat: 3% is a
  small cut against a 44% build and nothing here locates the threshold.
- **Zero of five registered retailer domains hold page one for "halloween candy."** The
  page is specialty sellers, recipe publishers, a drugstore and twix.com - a brand site.
  CVS is a retailer and was not registered; that part of the miss is ours.
- Two of five registered predictions came out wrong. A third held on a band no wider than
  the instrument's own resolution and is reported as a defective prediction rather than a
  clean hit. The raw year-over-year fall in costume search is 75.5% and is not used
  anywhere, because the base year is an outlier against its own history.

### A 94% audience score, and they were talking about Batman (October 26, 2026)
https://cultmath.com/research/film/clayface-audience

A standing study by Ipalibo Da-Wariboko of what a film's audience discusses when the film
posts a record audience score. Re-run as soon as October closes.

- **Clayface opened at $24.0M domestic on a ~$40M budget, number one for the weekend,
  with an A- CinemaScore and 94% on Rotten Tomatoes** - the best audience score DC has
  posted, against 76% with critics.
- **The 94% did not attach to the film.** Across 973 comments with ten terms registered
  before the pull: Batman 10.28% - a character not in the film - against the DCU at 2.88%,
  Gunn at 1.34%, all five craft terms combined at 1.03%, and a sequel at 0.41%. The word
  "makeup" appeared zero times on a film whose production story is practical makeup.
- **The $40M did not buy a bigger craft conversation.** Wicker opened the same weekend in
  the same genre for about a seventh of the money and ran 0.92% against Clayface's 1.03%,
  with 95% ranges that overlap almost entirely. Superman, same universe but not horror,
  ran 0.10% - lower, but its range touches Clayface's at the edge.
- **The author brand does not travel down the slate.** James Gunn appears in 14.3% of
  Superman's comments and 1.34% of Clayface's.
- **Critics and audiences are not arguing.** Five words a mixed review is written in
  appear in 0.46% of 653 comments; the highest single term reached 0.306%. The audience
  has not encountered the critics' verdict - though a searcher meets it first, because
  Rotten Tomatoes holds result one and leads with the 76%.
- **Demand peaked six months before release**, at 823,000 searches in April 2026 on the
  first trailer, against 368,000 in September. Over twelve months "clayface" averaged
  204,600 a month against 101,875 for "superman movie".
- **The engine returned four different corpus sizes for one query string in one run** -
  973, 973, 653 and 101. The central finding survives only because the two rows it rests
  on happened to match, which the page records as luck rather than design.
- Two of five registered predictions came out wrong, including the one held at highest
  confidence. A sixth, registered four days earlier - that the film would open between
  $22M and $34M - resolved as a hit at $24.0M.

### Every call we registered, including the ones we got wrong (October 26, 2026)
https://cultmath.com/research/predictions

The standing calibration ledger by Ipalibo Da-Wariboko. Every research prediction
registered before its data was pulled, with the basis it was set from and whether it
held. Updated whenever a study publishes or a dated prediction resolves.

- **Priors set from an earlier measurement with the same instrument hold 19 of 29 times
  (66%). Priors set from a plausible belief or declared as a guess hold 19 of 35 (54%).**
  An eleven-point edge, not an unbroken record — and the figure moves: it stood at nineteen
  points on October 26, 2026 and narrowed when one research pass added five reasoned misses
  in a single day. Measured priors do miss and beliefs land
  about half the time.
- **This page replaces a published figure that was wrong twice.** Until October 26, 2026
  CULT+MATH published a measured-basis record of 17 for 17 against 0 for 6 from belief.
  One prediction is recorded in its own calibration record as "not measurable,
  unresolved" and was tallied as a hit in a summary written the same day, taking 15 for
  15 to 17 for 17 when the correct figure was 16 for 16.
- **The larger error was coverage.** 26 of roughly 33 projects in the same window
  registered predictions with a probability band, a falsifier and a result and no basis
  label at all, so the published figure described about a fifth of the work while reading
  as though it described all of it.
- **One project supplies 54% of the classifiable sample and the edge vanishes inside
  it** — 64% against 62% within it, 86% against 42% outside it. That project registered
  22 predictions in 73 minutes. Recorded on the page as an open question, not explained.
- **Five priors are unresolved and are scored in neither direction.** Counting one of
  them as a hit is the error the page exists to correct.
- All 48 rows are published with their project, probability band, basis and outcome.

### Chinese AI demand is not falling. It is leaving DeepSeek. (October 28, 2026)
https://cultmath.com/research/ai/chinese-ai-rotation

A registered study by Ipalibo Da-Wariboko of whether a buyer holding an unsigned
multi-year AI contract gains anything by waiting for the China AI selloff to deliver
cheaper pricing. Twenty vendor terms, ten Chinese and ten Western, across the United
States, United Kingdom, Germany and Japan, read as monthly search volume from 2019 and
compared same-month year over year.

The answer is no. Western AI demand grew in all four markets with no break at the
July 1, 2026 boundary, so there is no demand-side cooling to wait for. Inside the
Chinese arm, Kimi grew 309-831%, GLM 177-529% and Qwen 22-173%, while DeepSeek fell
from a peak in January 2025 - eighteen months older than the index peak. DeepSeek is
78-90% of that arm in every market, so the arm total was reporting one name's decline
while three vendors inside it grew. The same rotation runs in the Western arm, where
OpenAI and Perplexity brand terms fell while Claude, Gemini and Anthropic multiplied.

Sixteen priors were registered before retrieval, ten were scoreable and five held. All
four registered explanations were rejected; the surviving explanation, rotation between
vendors, was never a candidate.

This study rests on one instrument. A second instrument sharing no operator, collection
method or population was registered before any data moved and was not run, because its
endpoint would not answer. It is therefore a finding about Google Ads search volume and
not yet a finding about Chinese AI, and the page says so in its opening.

### The best-reviewed animated film of the year had the least demand (October 27, 2026)
https://cultmath.com/research/film/animation-release-route

A registered study by Ipalibo Da-Wariboko of whether pre-release search demand can tell a
distribution chief which release route a finished original animated film should get. Eight
2026 original animated features and five franchise controls, three runs, every question
registered before retrieval.

- **The release routes already match the demand and do not overlap.** Wide theatrical runs
  12,100 to 135,000, streaming-first 2,900 to 6,600, and event cinema sits at 720. No film
  crosses a band, which says the distribution calls were right rather than that the
  instrument predicts them.
- **Wildwood holds a 100% critical score and the lowest demand of all eight.** 720 against
  Hoppers' 135,000, a factor of 188. LAIKA routed it to event cinema and it beat its own
  projection. Critical score orders none of these films by outcome.
- **Forgotten Island is where the decision failed.** Routed correctly and released wide on
  14,800 — 9.1x below the other wide-theatrical original that worked — to a bottom-five
  DreamWorks opening against an $80 million budget.
- **A single search term is not a measurement of a film.** Seven of eight titles read more
  than 3x differently across plausible constructions; Hexed spreads 450x and Wildwood 104x.
  Every figure on the page is the median of three constructions.
- **Pixar's Gatto carries demand sixteen months before release.** 19,600 against a
  pre-announcement baseline of 50, with no trailer campaign and no date in market.
- Twelve predictions registered before retrieval and scored after. Five of five held on the
  rebuilt instrument; the earlier single-term gate held one of seven and is reported
  separately.

### Netflix's 2026 slate opens at twice the demand of its 2023 slate (October 27, 2026)
https://cultmath.com/research/streaming/netflix-engagement

A registered study by Ipalibo Da-Wariboko of whether Netflix's falling engagement is a
thinning catalogue. Four runs, every question registered before retrieval. Cohorts are
the top ten series by hours in Netflix's own What We Watched reports for H1 2023 and H1 2026,
with a ten-title non-Netflix control.

- **The registered prediction missed by a factor of two.** We registered that the 2026 slate
  would open below the 2023 slate. It opens at a median of 748,000 searches against 368,000
  — 2.03x, and 2.24x once three broken search terms are removed. The catalogue is not the
  reason engagement is falling.
- **Platform search is falling across most of the category.** 2023 average to the twelve
  months ending September 2026: YouTube +35.3%, Disney+ +11.1%, Prime Video +9.6%,
  HBO Max -7.5%, Netflix -18.9%, Hulu -34.8%. Netflix's share of the six fell from 6.9%
  to 4.4%, mostly because the denominator grew.
- **The 2023 decay baseline is a category number, not a Netflix number.** Median retention
  of opening demand at three months in H1 2023: Netflix 12.2% across ten titles, a ten-title
  non-Netflix control 13.4%.
- **No retention comparison is published, because the measure does not support one.**
  Retention divides a later month by the opening peak, so a bigger opening scores worse as
  arithmetic rather than as behavior (r = -0.53 across 28 titles). The 2026 cohort spikes
  89x above its baseline against 11x in 2023, and a measure that nets the baseline out
  shows no difference at all. The 2023 figure is a like-for-like comparison against the
  control and stands on its own.
- Four of six registered predictions held. By basis: measured 1 of 1, reasoned 3 of 3,
  belief and declared guess 0 of 2.
- Search demand measures whether people look a title up, not whether they watch it. United
  States and English only. Google bands these figures, so directions are reliable and
  decimal places are not.

### One opened at twice the other. Three months later it was nine times smaller. (October 25, 2026)
https://cultmath.com/research/streaming/demand-decay

A standing study by Ipalibo Da-Wariboko of what happens to streaming demand after release.
Twenty 2026 titles screened against monthly search volume back to 2019; thirteen had a full
three-month post-release window. Re-run
quarterly, with the three-month ordering scored again at six months.

- **Median retention three months after release is 7.3% of the release-month peak, and the
  range runs 2.2% to 44.9%.** A twentyfold spread, so the median describes almost nobody in
  the panel and an industry-average decay rate is wrong in both directions at once.
- **Opening rank predicts rank and not retention.** Rank correlation from the release month
  to three months later is 0.841 across thirteen titles — but that is carried by the
  tail, where small titles stay small.
- **At the head of the chart it inverts inside a quarter.** Euphoria season 3 opened at
  3,350,000 searches a month against The Pitt season 2 at 1,500,000 — 2.2 times larger.
  Three months after each title's own release, The Pitt was at 673,000 and Euphoria at
  74,000 — 9.1 times larger the other way.
- **Two of four registered predictions are dead**, and the two that hold were registered as
  alternatives, which is a defect in the registration rather than a result. Both are published.
- **The contamination screen registered before the pull rejected twelve titles of nineteen
  and was too blunt**; a pre-release baseline cannot tell a different referent from legitimate
  anticipation. The refined screen, keyed to 2019 volume, rejects four. Both figures are
  published and the registered one is not quietly replaced.
- **The qualitative half is reported as context, not evidence.** Two of five comment terms
  discriminate against a negative control, against none in the study's first pass, and no
  term maps onto the retention figures.

Limits stated on the page: search volume is interest and not viewing; Google bands and rounds
these figures; the panel is declared rather than drawn from a register; eleven of thirteen
titles are returning seasons.

### An entire industry vacated twelve days (October 25, 2026)
https://cultmath.com/research/games/release-corridor

A standing study by Ipalibo Da-Wariboko of the game release calendar around the
November 19, 2026 launch of Grand Theft Auto VI. Three published calendars, every dated
title October to December, measured within each source and never across them.
Re-checked after November 19.

- **The twelve days from November 13 to 24, 2026 contain exactly one dated title in each
  of the two fullest calendars — and it is Grand Theft Auto VI itself.** No game at all
  is dated to November 19.
- **The twelve days immediately before are the busiest stretch of the autumn.** In
  GameSpot's calendar November 1–12 runs 2.33 dated titles a day against October's 2.10;
  November 13–24 runs 0.08. A ratio of 28 to 1 inside one month.
- **Video Games Chronicle's much sparser calendar shows the same shape** — 7 titles in
  the first twelve days, 1 in the next twelve, and eleven clear days after the launch
  before anything else is dated.
- **"Number of games released in November" is not a quantity.** Three published calendars
  give 4, 8 and 31 dated titles for the same month — an eight-fold disagreement, because
  each admits different indie releases, platform ports and remasters. Any year-on-year
  release comparison needs the same source on both ends, and most published ones do not
  have it.
- **The registered study could not be run, and the page says so first.** It registered a
  demand-displacement measurement needing a panel of same-genre titles in the window. The
  panel has one title in it, and that title is the launch. The four registered candidates
  are recorded as unscorable rather than quietly replaced.
- **The decision this was built for is already settled.** A publisher weighing whether to
  ship into the window can see that an entire industry independently vacated the same
  twelve days. The absence of competitors is an opportunity signal only if the
  competitors failed to notice it.
- **The strongest argument against the finding is on the page.** US Thanksgiving falls
  November 26, 2026, inside the thin stretch. The first half of November controls for a
  holiday effect partly and not wholly, and it is testable in a year where a generational
  launch and the holiday do not coincide.
- **GTA VI's date was confirmed at Rockstar's own newswire** before anything was
  measured, because it has moved twice before.

### The chip supply chain did not broaden. It changed address. (October 25, 2026)
https://cultmath.com/research/semiconductors/sourcing-concentration

A standing study by Ipalibo Da-Wariboko of partner concentration in US semiconductor
imports, 2019 to 2024, across three trade lines, against the gross margins of 41
semiconductor and 23 hardware SEC filers. Every partner share, every
filer and every exclusion published.

- **US integrated-circuit imports: the largest partner fell from 47.1% to 28.1%, but the
  top three still hold 62.3% against 64.8% in 2019.** Concentration moved address rather
  than falling.
- **Malaysia lost 23.3 points of share and two countries took nearly all of it** — Taiwan
  +16.9 and Israel +10.0. Next largest gains: Costa Rica +3.0, Ireland +2.2, Germany +1.1.
- **2024 shares of a $40.39bn total:** Taiwan 28.1%, Malaysia 23.8%, Israel 10.4%, South
  Korea 6.0%, Ireland 4.7%, Mexico 3.7%, China 3.6%, Vietnam 3.5%.
- **UN Comtrade reports Taiwan as "Other Asia, nes."** Anyone filtering for "Taiwan" by
  name records the largest single share movement in the data as missing.
- **A second trap in the same data:** requesting partner detail returns the individual
  countries AND a World aggregate in one list, summing to $80.77bn against a $40.39bn
  world total. Of 310 entries in Comtrade's partner reference, exactly one is flagged as
  a group.
- **The answer differs by trade line.** Integrated circuits relabeled. Discrete devices
  dispersed into Vietnam +9.6, Thailand +9.3, India +6.0 and Cambodia +5.9 at once, yet
  the top three ended MORE concentrated. Semiconductor manufacturing machines genuinely
  diversified — top three fell from 77.9% to 54.2% with no single winner above 6.3.
- **All four registered candidates are true of at least one line and none is true of all
  three.** The question was asked at category level and the category has no single answer.
- **Supplier margins rose.** Median gross margin across 41 semiconductor filers went from
  38.67% to 40.62%, up 2.22 points, with 28 of 41 expanding. Removing the four largest
  AI-exposed names moves it only to +1.83, so it is not an Nvidia artifact. A hardware
  panel of 23 filers rose 1.41 points.
- **Intel has the worst gross-margin collapse in the panel at −23.79 points**, from 58.6%
  to 34.8%, and is the filer that pursued domestic capacity hardest. Nothing in the study
  establishes causation; the narrower claim that survives is that it did not get paid for
  it in gross margin over this window.
- **What it cannot say:** trade data records a border crossing, not a fab. A chip packaged
  in one country from a wafer made in another is attributed entirely to the packager.

### Costs did not fall. They split. (October 25, 2026)
https://cultmath.com/research/cpg/margin-recovery

A standing study by Ipalibo Da-Wariboko of gross margin across every US food and
household SEC filer above $1bn in revenue, against a seeded control outside the category
and against what the inputs actually cost. 1,631 filers screened. Re-run
each filing season. Every filer published, including the twelve excluded and the reason
for each.

- **Median gross margin across 42 US food and household filers FELL 0.92 points**, from
  38.93% in FY2019 to 35.94% in the latest filed year. Only 14 of the 42 expanded.
- **A seeded control of 15 filers outside the category moved the opposite way, up 1.99
  points**, from 38.19% to 39.84%. The category and the control diverging is what makes
  this a category result rather than an economy-wide one.
- **Input costs did not fall as a block — they split.** US import unit values 2022 to
  2024: cocoa beans +109%, chocolate preparations +26%, bananas +7%, rice +4%, coffee
  +1% — against soybean oil −27%, palm oil −25% and aluminium plate −16%. The oils and
  the packaging metal came down; the tree crops went up.
- **The two worst-hit filers in the set are the two largest chocolate companies.**
  Hershey −11.81 points (45.4% to 33.5%), Mondelez −11.59 (40.0% to 28.4%), over a
  period when cocoa bean import values more than doubled.
- **The best movers have no tree-crop exposure:** Celsius +8.73, Coca-Cola Consolidated
  +5.13, Ingredion +4.19, Kellanova +3.38, Pilgrim's Pride +3.37, Coty +2.63.
- **By industry group, sugar and confectionery was worst at −5.96 points** while bottled
  and canned soft drinks gained 2.13 over a period when aluminium fell 16%.
- **There is no useful category average.** Latest gross margin runs 13.8% at the tenth
  percentile to 61.2% at the ninetieth — a 47 point spread against a median six-year
  movement of under one point. The gap between companies is roughly fifty times the
  movement over time.
- **Two of four registered predictions came out wrong and both are published**, including
  the leading one: we expected margins widened on falling commodities, and they compressed.
- **A measurement finding that stands on its own: you cannot compute gross margin from
  SEC XBRL by picking a revenue tag by name.** Archer-Daniels-Midland tags both $27.6bn
  and $101.6bn for FY2022 against cost of revenue of $94.0bn; precedence yields −240%.
  Testing each candidate against cost of goods changed the figure in **196 of 264
  multi-candidate filer-years, across 50 of 57 filers**. General Mills tags gross profit
  only quarterly — 128 facts, every one a quarter.
- **What it cannot say:** no filing prose was read, so there is no price-versus-volume
  split and no management explanation. Causation between commodity exposure and margin is
  inference, not evidence. The consumer side and the customer-voice half are not in this
  pass, and the page says the read is unfinished without them.

### Two AI engines, two different security vendors, 72.7% of the time (October 19, 2026)
https://cultmath.com/research/cybersecurity/vendor-recommendation-disagreement

A standing study by Ipalibo Da-Wariboko of twenty buyer-intent cybersecurity questions put
three times each to ChatGPT and Perplexity. 99 of 100 rows. Re-run quarterly. All twenty
questions are published, including the nine excluded from the headline rate.

- **On the eleven questions where both platforms were consistent with themselves, the two
  named a different leading vendor on eight — a 72.7% disagreement rate.** The three they
  agreed on were identity and access management (Okta), container security (Trivy) and threat
  intelligence (Recorded Future), the three categories with one obvious canonical answer.
- **Cross-platform citation overlap ran at a median of 3.8%.** A parallel entertainment
  measurement ran at 12.5 to 16.7%, so the denser commercial corpus of a B2B category pushed
  the platforms further apart rather than pulling them together. This fired a registered
  falsifier written specifically to kill the hypothesis.
- **ChatGPT citation stability: 17.2% median. Perplexity: 100.0% on all twenty questions.**
  ChatGPT named a different leader across three identical calls on 8 of 20 questions;
  Perplexity on 2 of 20, so its answer layer is less reliable than its citation layer.
- **Eleven rows cited zero domains and every one of them was ChatGPT** — all three calls on
  SIEM, cloud security posture and penetration testing, and two of three on security
  orchestration. The vendors were still named. Perplexity cited between seven and ten domains
  on all forty of its rows and was never empty.
- **One top recommendation was sourced to the vendor's own press release on a paid newswire.**
  Asked for the best EDR platform for a mid-size company, ChatGPT led with Seceon, cited to a
  syndicated company growth announcement, alongside a Japanese SaaS listing and an Italian
  software-licensing reseller. A US buyer asking that question is being answered in part from
  foreign reseller listings.
- **The engines read review and comparison databases, not security trade press.** Of six
  source types registered before retrieval, G2 appeared in 14 rows, Gartner in 9, CSO Online
  in 2 and TrustRadius in 1 — while Dark Reading and BleepingComputer appeared in none.
- **Two of four registered predictions came out wrong and both are published.** The
  disagreement rate was predicted at 30–60% and came in at 72.7%; citation overlap was
  predicted higher than entertainment's and came in three to four times lower.
- **The commercial consequence: these are two channels, not one.** A vendor optimizing for
  "AI visibility" as a single thing is optimizing for an average of two populations that
  share 3.8% of their sources.
- **What it does not establish: which platform is right.** Nothing in the study measures
  accuracy. Both engines were read at platform-default budget tiers — gpt-4.1-mini and sonar.

### Disney built its own premium format because it could not get a screen (October 24, 2026)
https://cultmath.com/research/film/premium-format-exclusivity

A standing study by Ipalibo Da-Wariboko of the December 18, 2026 collision between
Avengers: Doomsday and Dune: Part Three. Re-run weekly until December 18. The registered
prediction resolves Monday, December 21, 2026 and is scored on the page either way.

- **Dune: Part Three holds the US IMAX screens for the opening of December 18, 2026**, which
  IMAX confirmed in an investor presentation reported in February 2026. Avengers: Doomsday
  cannot play IMAX that weekend.
- **Every demand instrument measured puts Avengers: Doomsday ahead**, four of five by more
  than 70%: head search term 95.3%, trailer searches 96.8%, official-trailer comments 86.1%,
  trailer views 64.9%. Ticket searches, the measure closest to purchase intent, is the
  narrowest at 73.2% — Dune closes the gap as the question moves from awareness to buying.
- **Every answer engine that will recommend at all recommends the other film.** Perplexity
  named Dune: Part Three in all three identical calls and gave the premium-format reason each
  time. ChatGPT declined to choose in two of three.
- **The duration both engines gave appears in none of the sources they cited.** Perplexity
  said the exclusivity runs "at least its first three weeks" and cited a GamesRadar article
  that states no duration at all. The three-week figure traces to a post on X, reported by a
  film blog that hedged it. The claim that traces to IMAX's own investor presentation
  describes the opening weekend. The engines gave the longer, unsourced version with a real
  citation attached.
- **The studio that lost the screens built a competing format.** Disney announced Infinity
  Vision, its own premium large-format certification program, at CinemaCon on April 16, 2026 —
  seven weeks after the IMAX investor presentation — and reported more than 7,500 screen
  applications by late June. IMAX's own chief financial officer called it a marketing play.
- **Neither engine cited Variety, Deadline or The Hollywood Reporter once across twelve
  calls.** ChatGPT's first-position citation on two of three open calls was a Peruvian news
  site, on a question about a US December release.
- **Sixth consecutive replication of the citation-stability finding.** ChatGPT returned six
  domains across three identical open-question calls with zero stable across all three.
- **A second prediction, P4, registered October 25, 2026 at 75%.** Dune: Part Three's IMAX
  domestic per-screen average beats Avengers: Doomsday's Infinity Vision per-screen average on
  opening weekend. Its basis is a structural argument about screen counts rather than a
  measurement, and it is labeled as such on the page. It is recorded unresolvable rather than
  wrong if per-screen averages for both formats are not reported by January 9, 2027. The three
  earlier predictions on the page — P1 Avengers takes the larger three-day domestic gross at
  65%, P2 Dune takes it at 30%, P3 the two land within 5% at 5% — resolve from three-day
  domestic grosses reported December 21, 2026.
- **The calibration figures on this page were corrected on October 26, 2026.** The page had
  stated that priors set from an earlier measurement stood at 17 for 17 and priors set from
  belief at 0 for 6. An audit of the underlying records found a prior recorded as unresolved
  and tallied as a hit, and found that most projects registered priors with no basis label at
  all. Rebuilt from the priors carrying an explicit basis: 19 for 29 measured against 19 for
  35 from belief — an eleven-point edge rather than an unbroken record, as of October 28, 2026.
  The edge is computed on the live ledger and moves as passes are scored.
  Perplexity returned a fully identical nine-domain set on both question shapes.
- **movies.disney.com was cited at position 1 on two of three head-to-head calls**, against
  zero owned citations for the publisher in the games study. The difference is that this
  question named both titles.
- **The study's own brief had the release date wrong and the page says so first.** The brief
  said December 19; all six model answers said December 18, and they were right.

### Your category's advertising benchmark is noise (October 25, 2026)
https://cultmath.com/research/marketing/advertising-intensity

A standing study by Ipalibo Da-Wariboko of disclosed advertising spend as a share of
revenue, read from the SEC XBRL frames API across 1,633 filers. Re-run each filing
season.

- **Advertising intensity does not cluster inside an industry.** Three unrelated SIC
  groups returned medians of 2.01%, 3.22% and 3.30% — close to each other — while the
  spread inside each one was far wider than the gap between them.
- **The coefficient of variation inside every category exceeded 1.0**, the
  pre-registered threshold for "category tells you almost nothing": 2.21 for
  prepackaged software (n=137), 6.10 for pharmaceutical preparations (n=61) and 1.51
  for business services (n=40). One of four registered candidates survived.
- **A peer benchmark quoted as a category median is therefore not a constraint.** Two
  companies in the same SIC code routinely sit an order of magnitude apart, so a budget
  defended as "in line with our category" is defended against a number that does not
  hold.
- **Pharmaceutical preparations was the widest, and one filer caused it.** Dropping a
  single outlier moved the category's CV from 6.10 to 1.49 on n=60. The figure is
  published both ways rather than cleaned.
- **Take-Two Interactive disclosed 19.34% for the fiscal year to March 2026**, roughly
  six times its software category's median. Maplebear (Instacart) 13.53% and DoorDash
  12.12% for CY2024; Electronic Arts 4.70%, Uber 4.32%, Lyft 2.55%.
- **Twelve of 250 candidate rows were rejected by validation and all twelve are
  published**, with the reason for each. They include an order-of-magnitude tagging
  error that had been sitting fifth in the raw ranking, and Eli Lilly, rejected over a
  2.9% disagreement between two tags of the same period.
- **One of the twelve rejections was a false positive and the page says so.** Reshape
  Lifesciences was rejected by a name check over a legitimate corporate rename.
- **The data is free, public and dated.** Everything here comes from the SEC's XBRL
  frames API, which anyone can call; the study's contribution is the validation and
  the spread, not access.

### GTA 6: who answers, what it costs, and what people say (October 24, 2026)
https://cultmath.com/research/games/gta

A standing study by Ipalibo Da-Wariboko of Grand Theft Auto VI as a measurement subject.
Re-run weekly.

- **Grand Theft Auto VI releases Thursday, November 19, 2026**, on PlayStation 5 and
  Xbox Series X|S. Confirmed by Rockstar on November 6, 2025 after two delays.
  Pre-orders opened June 25, 2026; digital pre-loads begin November 12, 2026. No PC
  date announced. All six AI calls in the study returned this date.
- **The identical query string put to ChatGPT, Perplexity and Google returned zero
  domains in common.** Not one domain appeared in any two of the three source lists.
- **ChatGPT cited seven domains across three identical calls and only one appeared in
  all three.** On the third call all four citations were purpose-built GTA wiki sites
  and Rockstar's own domain was never cited at all.
- **Perplexity returned the same ten domains in the same order on all three calls.**
- **Six of the 17 domains the two answer engines cited are sites that exist to answer
  questions about this one game**, including both of Perplexity's top two positions.
- **Google was less consistent with itself than Perplexity was.** Two phrasings of the
  same question, same engine, same city, same minute, shared one domain of six.
- **Take-Two advertising intensity was 19.34% for the fiscal year to March 2026**
  ($1,287,100,000 on $6,656,400,000), after a 4.08x step up in FY2023 that coincides
  with the Zynga acquisition. The Zynga explanation is labeled a hypothesis because
  the filing has not been read.
- **Thirteen of the top thirteen keywords are release-date variants** at 823,000 to
  1,500,000 searches a month. There is no analysis-intent query in the top fifty.
- **A YouTube search run three times in one hour returned three different corpora.**
  One corpus replaced nine of ten members between consecutive runs.
- **Pre-release comment sections carried no commercial vocabulary.** The same channel
  covering a shipped game returned "campaign" in 20% of comments and unprompted price
  talk; covering an unreleased one it returned character names and the host's name.
- **People self-report taking time off work for the launch.** On a TV report framing
  the launch as a billion-dollar productivity loss, "day" appeared in 25% of the top
  200 comments, "week" 14.5%, "work" 12.5%, "vacation" 6.5% and "my job" 5%. All three
  economically-framed corpora showed this and none of the three gameplay-analysis
  corpora did. Self-reports in public comments, not a survey.
- **A registered test returned no verdict and the page says so.** A commercial-vocabulary
  coder fixed before the pull found a mean of 1.4 terms in the finance corpora against
  0.33 in the analysis ones, which fell between the pre-registered thresholds. The
  labour-vocabulary result above is published as an unregistered observation.
- **A claim was retracted in the same pass that measured it**, on the page, dated.

### The IP Association Map (October 18, 2026)
https://cultmath.com/ip-association

A registered study by Ipalibo Da-Wariboko of who gets cited when a language model
is asked about a brand's commercial associations. 89 measurements across 10 passes,
30 questions, 12 brands, three runs each, every prediction registered with a
probability band before the data was pulled.

- **When the question names the brand**, the brand's own domain was cited in 82% of
  rows (32 of 39, origin questions excluded).
- **When the question leaves the brand unnamed**, 42% (14 of 33).
- **Founding and origin questions returned zero owned citations across 17 rows.** In 9
  rows the model ran no search at all, answering from memory at roughly 320 input
  tokens instead of 8,174.
- **Rewording one question flipped the result.** "Which watch brand is Jon Rahm an
  ambassador for?" cited rolex.com zero times in three runs. "Is Jon Rahm a Rolex
  testimonee?" cited rolex.com first, three times out of three. Same fact, same brand,
  same page, eleven minutes apart.
- **Two conditions have to hold together:** the brand must have content about that
  specific association on a domain it controls, and the question has to reach it.
  Neither is sufficient alone. Rolex had the page and lost until the question changed;
  TAG Heuer was not cited for Jacob Elordi in either phrasing, because rewording
  cannot surface a page that does not exist.
- **Brands are often answered by their press hubs, corporate parents and regional
  storefronts rather than their main site** — mediahub.puma.com, about.puma.com,
  newsroom-content.rolex.com, press.omegawatches.com, magazine.tagheuer.com,
  diageo.com and swatchgroup.com. In five rows a non-production host was cited,
  including staging.fossilgroup.com at position 1 on a question about Fossil's products.

**Citation is not demand.** The study measured citation only. None of the 89 rows
measured willingness to pay, traffic, search volume or revenue, and a citation share
should not be reported as a demand figure.

**Calibration.** Of 11 registered predictions, 4 held, 6 failed and 1 split. Five
published conclusions were retracted the same day, each with a timestamp, and the
full ledger including the misses is on the page.

Method: ADMADS Engine, DataForSEO AI Optimization live endpoint, gpt-4.1-mini-2025-04-14,
web search enabled, United States and English, three runs per question.
