Belief perseverance, which is the tendency to cling to one's initial beliefs even when presented with contradictory evidence, could lead researchers to stick to their original methods and conclusions despite failed replications. Self-serving bias, which is the tendency to interpret information in a way that is favorable to oneself, could also play a role as researchers may have a vested interest in their work being successful. However, the tendency to stick to one's initial beliefs in the face of contradictory evidence is a more direct explanation for why replication may fail across different laboratories.
