Survey + classic experiments: what this kind of study can — and can't — tell parents

This episode pairs a modern parent survey with classic laboratory experiments — two designs that answer the same question from opposite directions.

What it can show

The experiments can show cause (praise type changed behaviour); the survey shows how the pattern looks in everyday family life.

What it can't

The survey half is observational, so its balance finding is phrased as linked to — the causal claims belong to the experiments alone.

Too Much ‘Good Effort’ Praise Backfires Too

Try tonight: Praise the process a little more than the person: mostly specific effort-and-strategy praise, a light touch of person praise, and never a flood of either.
