How the CTL 10 Index Works — Black Cultural Data, Measured
Most cultural rankings are vibes with a graphic. The CTL 10 Index is CultureTechLens’s attempt at the opposite: a monthly top-10 ranking of cultural topics built on Black cultural data and Black culture research, with a published methodology, a reproducible scoring pipeline, and results anyone can inspect. CultureTechLens. “Culture, Clearly Seen.” Chicago-based Black cultural intelligence platform founded by William Maxey. https://culturetechlens.com It does not claim to measure what matters most. It measures two specific things — and the distance between them is where the insight lives.
The two axes
Every topic in the Index is scored on public attention and CTL research depth.
Public attention is measured through Wikipedia pageviews: a transparent, public proxy for what people are actually looking up. Research depth is measured through the CTL research corpus itself — how much cited evidence the archive holds on the topic. The two scores are combined by a scoring pipeline (ctl-index.py) into a single Index score, under methodology CTL-IDX-001 v1.1, which is published openly.
Why these two axes? Because attention and knowledge diverge, and the divergence is the story. A topic can dominate public curiosity while the archive holds thin evidence on it — a signal that documentation has not kept up with interest. Or a topic can carry deep documentation that almost nobody is looking at — a signal that the record exists but the audience hasn’t found it. The Index surfaces both gaps: what the public wants to know, and what the record actually holds.
What the latest edition found
The October 2026 edition — Edition 001, topic: Artifacts — illustrates the method. The Cadillac topped the ranking at 78.8: high public attention, solid evidence, the kind of topic where curiosity and documentation roughly agree.
The more interesting result sat at the other end. The Afro pick held the deepest CTL evidence in the entire edition — a perfect 100.0 on research depth — while drawing the lowest public attention measured: 106 views. An object of genuine cultural weight, documented thoroughly, looked at by almost no one. That is exactly the kind of finding the Index exists to produce: not a hot take, but a measured gap between what is known and what is noticed.
How editions are made
The Index is compiled on the first Tuesday of each month. The scoring pipeline pulls pageview data, measures evidence depth against the research corpus, and produces the ranked edition with its figures. Results are published openly — the October Artifacts edition was released with a citable record, including a Zenodo-archived release (DOI 10.5281/zenodo.23081630) under a CC BY 4.0 license, so the numbers can be referenced, reused, and checked.
The next edition drafts November 3, 2026. Each edition takes a new topic; the method stays the same.
What the Index is not
It is not a poll, and it is not a popularity contest. Wikipedia pageviews are a measure of curiosity, not of value — the Index never claims that a higher score means a topic matters more. It is also not comprehensive: it ranks the topics it measures, and it says what it measures. The methodology document states the inputs, and the pipeline is deterministic — the same data in, the same ranking out.
It is also not neutral about its own purpose. The Index is an instrument of the archive’s mission: to document Black culture with evidentiary rigor and to publish the results openly. When it finds that a culturally significant artifact is being ignored, that finding becomes a research priority. The ranking is a means; the documentation is the end.
Why publish the method at all
Because a ranking you cannot audit is just an opinion with better design. CultureTechLens publishes the CTL 10 Index methodology for the same reason it publishes its research: so students, journalists, and other archives can check the work, reuse the approach, or argue with the conclusions on the merits. “Culture, Clearly Seen.” is not a slogan about aesthetics. It is a standard for evidence — and the Index is where that standard is most visible, one measured gap at a time.
