Calling Bullshit — Start Here
Bergstrom and West, two university scientists who developed a popular course on the subject, argue that navigating a world saturated with numbers, statistics, and data visualizations requires a practical, learnable toolkit for spotting claims designed to persuade without regard for whether they are true. Rather than teaching cynicism, the book presents "calling bullshit" as a civic skill: recognizing common statistical sleights, reading charts and graphs skeptically, distinguishing correlation from causation, and asking whether a claim could even in principle be shown false, all in service of a healthier, more honest shared discourse.

Bergstrom and West, two university scientists who developed a popular course on the subject, argue that navigating a world saturated with numbers, statistics, and data visualizations requires a practical, learnable toolkit for spotting claims designed to persuade without regard for whether they are true. Rather than teaching cynicism, the book presents "calling bullshit" as a civic skill: recognizing common statistical sleights, reading charts and graphs skeptically, distinguishing correlation from causation, and asking whether a claim could even in principle be shown false, all in service of a healthier, more honest shared discourse.
How the mechanism works
- Spotting numbers used to mislead rather than inform: recognizing common statistical sleights such as a cherry-picked starting point, a misleading percentage, or a sample that does not represent what it claims to.
- Reading visualizations skeptically: charts and graphs can distort scale, truncate an axis, or otherwise imply a trend the underlying data does not actually support.
- Distinguishing correlation from causation and testing falsifiability: a habit of asking whether an apparent relationship might have another explanation, and whether a claim is specific enough that it could, in principle, be proven wrong.
- Skepticism as a civic skill, not cynicism (single framing paragraph, no break/practice line): this package treats fact-checking and healthy doubt as an act of respect for shared discourse and for the people a claim is aimed at, exercised out of care rather than contrarianism for its own sake.
Who this was written for
A generally educated adult who regularly encounters statistics, charts, and data-based claims in the news, at work, or online, and wants a concrete, non-technical toolkit for evaluating them rather than either accepting every number at face value or dismissing all of them out of blanket distrust.
Moderate tier (ACT; living co-authors whose university course continues under their names). The two credited authors (Carl T. Bergstrom and Jevin D. West) are named together and never separately, extending this factory's standing multi-author-confinement safeguard. No real study, poll, news report, statistic, or data visualization is reproduced; every illustrative example of a misleading chart, cherry-picked statistic, or false-causation claim is invented and clearly generic. Heightened political and ideological evenhandedness applies throughout: no real politician, political party, news outlet, or specific real controversy is named or used as an example of a misleading claim anywhere in any persona file. No fabricated statistics, percentages, or study details beyond what the source qualitatively describes. Framework fidelity expected around 8, since the source's numbers/visualizations/causation structure maps cleanly onto three of the four clusters.
Cross-book note
Fifth and closing title in the Statistical Thinking, Misinformation, and Everyday Media Literacy category. Its own vocabulary centers on statistical sleights, visualization skepticism, and correlation-versus-causation — kept distinct from Factfulness's dramatic-instincts vocabulary, The Signal and the Noise's probabilistic-forecasting vocabulary, Amusing Ourselves to Death's medium-shapes-message vocabulary, and The Filter Bubble's invisible-personalization vocabulary.
