A NOTE FOR CURIOUS MINDS

Behind the joke.

One company's growth story, told confidently from a stage, is an anecdote rather than evidence. Tripling top-of-funnel spend will usually lift top-of-funnel numbers; the real question is whether the extra spend paid back in profitable customers, compared with what would have happened anyway. Applause measures how persuasive the speaker was, not whether the strategy works.

Dr. Bayes: And the evidence?

Dr. Bayes: False prophets usually do.
