 The social process of peer review is thought to mitigate the effect of individual scientists' biases, even though the peer review process itself may be susceptible to such biases  Confirmation bias may thus be especially harmful to objective evaluations regarding nonconforming results since biased individuals may regard opposing evidence to be weak in principle and give little serious thought to revising their beliefs.Scientific innovators often meet with resistance from the scientific community, and research presenting controversial results frequently receives harsh peer review.Confirmation bias can lead investors to be overconfident, ignoring evidence that their strategies will lose money.
