Accepted Answer

A classic experiment showed people walk slower right after reading words about old age. For thirty years it was in every textbook — until repeat studies in 2012 could not find the effect anymore. It became the start of psychology's "replication crisis".

Een klassiek experiment liet zien dat mensen langzamer gaan lopen als ze net woorden over ouderdom hadden gelezen. Dertig jaar lang werd het in elk handboek genoemd — tot herhalingen in 2012 het effect niet meer konden vinden. Het werd de start van de "replicatiecrisis" in de psychologie.
