Replicated effects were half the magnitude of original effects. 97% of original studies had significant results; only 36% of replications did.
Le Texier, 'Debunking the Stanford Prison Experiment,' American Psychologist (2019)DOI registry: valid
Guards were coached by experimenters, data was cherry-picked, and conclusions were not supported by the evidence.
Burger, 'Replicating Milgram,' American Psychologist (2009)DOI registry: valid
Partial replication found similar obedience rates at 150V, but full replications are ethically impossible. Perry (2012) revealed significant methodological problems in the original.
Bond & Smith, 'Culture and Conformity: A Meta-Analysis,' Psychological Bulletin (1996)DOI registry: valid
Asch conformity rates have declined over time and vary hugely by culture. The effect exists but is much smaller and more context-dependent than the original ~75% figure.
