Systematic distortions that arise from the way rationality is defined, valued, and deployed in different contexts. Rational Biases include: assuming that rationality is universal rather than culturally specific; treating emotional responses as inherently irrational; privileging instrumental reason (means-end calculation) over other forms of reason; assuming that rational actors exist in economic theory; using "rational" as a term of approval rather than a description. Rational Biases shape not just how we think but how we judge thinking—in ourselves and others.
Rational Biases "She called his response 'emotional' and therefore irrational. That's Rational Bias—assuming emotion and reason are opposites. But emotions can be rational responses to situations; reason without emotion is calculation without wisdom. Rational biases make us miss the rationality in feeling and the feeling in rationality."
