Assuming two things are causally connected just because they happen together.

Two things move together, so one is declared the driver. Correlation is a clue; causation needs a mechanism and better evidence.

01

What it sounds like

  • People who buy expensive workout gear are fitter, so the clothes make them fit.
  • "High performers drink this coffee, so this coffee creates high performers." Or high performers are tired. Revolutionary.
02

How to tell

  • The argument shows association but skips direction, confounders, and mechanism.
03

Why people use it

  • Patterns feel persuasive, especially when graphed in a serious color.
04

How to combat it

  • Say: "What mechanism connects them, and how did you rule out a third variable?"

Manipulation watch

How this gets used on people.

  • Wellness and productivity marketing often turns lifestyle correlations into product promises.
