Aristotle defined humans as the rational animal. But he was wrong! The human mind is riddled with cognitive biases. At last count, there are something like 150 named cognitive biases – confirmation bias, in group bias, loss aversion, the Ikea effect, the halo effect, endowment effects.
What is it
Aristotle thought that rationality was the faculty that distinguished humans from other animals. However, psychological research shows that our judgments are plagued by systematic, irrational, unconscious errors known as ‘cognitive biases.’ In light of this research, can we really be confident in the superiority of human rationality? How much should we trust our own judgments when we are aware of our susceptibility to bias and error? And does our awareness of these biases obligate us to counter them?
