The view that cognitive processes divide into two main kinds. One type is fast, automatic, associative, impulsive, effortless, and emotional. The other is slow, controlled, reflective, conscious, effortful and cool-headed. The first gives us snap judgements, or instant emotional reactions, whereas the second permits conscious thought, inferences, rival hypotheses, and the weighing of conclusions. The first buys speed at the expense of gullibility; the second potentially corrects it. The distinction became widely known with the publication of psychologist Daniel Kahneman’s book Thinking Fast and Slow in 2011. It has been argued that the distinction corresponds better to that between Plato’s charioteer (the slow process, or user of logismos) and the unruly horses which need his control (the fast process, which is alogistikos) than the traditional model of emotions under the authority of rationality.
