The replication crisis

What changed and why.

What happened

Systematic attempts to repeat published studies found a large share did not hold. Small samples, flexible analysis and publication bias explain most of it.

  • Power posing, ego depletion and many priming results failed to replicate.
  • The response, pre-registration and larger samples, has measurably improved quality.

Reading psychology now

Prefer replicated findings and meta-analyses over single striking studies. A result that made a good headline is a reason for more scepticism, not less.
