How appealing an explanation is, is only in part down to how well it actually *explains*, research by klopfenstein.bsky.social & @hugoreasoning.bsky.social suggests.

Usefulness and surprisingness matter too, the latter especially explaining why poor explanations become popular:

Woah.

Argentina's 1990s preschool expansion program appears to have been a smashing success.

The program increased high school completion by a whole 11.9 percentage points.

The authors estimate that for every $1 spent, the preschool expansion generated about $11 in benefits.
