When stereotypes backfire: Trying to suppress stereotypes produces false recollections of a crime

Purpose . This study examined whether participants' memories of a racially neutral crime story are influenced by stereotypes and the instruction to suppress stereotypes while reading the crime story. We expected that participants who saw a photograph of a foreign group (negative stereotype prime) and were given the instruction to suppress stereotypes before reading a crime story would make significantly more stereotype‐consistent errors on a recognition test than participants who received a neutral prime and a suppression instruction. Methods . Participants were 88 undergraduate students (59 women) who were randomly allocated to the cells of a 2 (negative stereotype versus neutral prime)×2 (thought suppression versus control) between‐subjects design. The dependent variables were recognition of accurate items, stereotype‐consistent items and confabulation items. Results . The critical stereotype × suppression interaction was statistically significant for false recognition of non‐presented stereotype‐consistent items. Simple effect analyses of the suppression condition showed that participants who were primed with a negative stereotype made more stereotype‐consistent recognition errors than those who had been exposed to a neutral prime. Conclusions . Stereotypes not only make cognitive processing easier, but might also contribute to recognition errors when people do what they often are told to do in the legal arena: suppress stereotypical thinking.
