Interactive explainers
Pages that teach one idea by letting you play with it. Every page is live — disagree with a claim and you can pin a note right on it.
The truth-seeking series
Seeing reality more clearly: biases, base rates, and the questions that puncture comfortable stories.
Bayes & base rates — you tested positive. How worried should you be?
An interactive Bayes' theorem explainer: 1,000 countable people show why a 90%-accurate test doesn't mean a 90% chance you're sick. Base-rate neglect, made visible.
Open the explainer →Survivorship bias — where would you armor the bomber?
Abraham Wald's WWII bomber problem as an interactive puzzle: place armor on the damage map and learn why the bullet holes you can see are the ones that don't matter.
Open the explainer →Customer interviews — your mom will lie to you. So will your customers.
Five customer-interview questions that invite polite lies, rewritten live. An interactive take on Rob Fitzpatrick's Mom Test: ask about their life, not your idea.
Open the explainer →Startup idea autopsy — a kill-your-idea template to fill in
A fill-in idea autopsy: score each assumption by how bad it'd be if wrong and how little evidence you have, then attack the riskiest first. Kill your idea before the market does.
Open the explainer →Preference falsification — everyone thought everyone else believed it
A threshold-model crowd simulator (Granovetter, Kuran): watch a belief everyone privately rejects survive because everyone waits for someone else to speak first.
Open the explainer →The distribution series
Getting seen without an audience: plays that borrow existing attention flows instead of grinding out followers.
Distribution without an audience — the seven plays, mapped
The seven distribution plays for products with no audience, mapped interactively from Melvin Luu's essay: MCP servers, AEO, free tools, programmatic SEO, shareable artifacts, newsletter acquisition, affiliates.
