Thomas Ames (pictured above) is a graduate student in philosophy at the University of Missouri-St. Louis and has interests in epistemology, agency, and disorders of selfhood. In this post, he summarizes some of his current research into what role irrational emotions may play when making rational decisions, and what that may mean for the future of artificial intelligence.
Quite a bit has been written on the role of emotion on the decision-making process. Using cases of traumatic brain injuries that have led to defects in both emotion and rational decision-making, several theories with a neurological framework have been proposed about why that may be. One such prominent theory, somatic marker hypothesis (1, 2), introduced by Antonio Damasio (University of Southern California), posits that emotions play an integral neurological role in decision-making. This is because it was found that in cases of specific brain lesions which affect patients’ emotions, their abilities to make decisions were also adversely affected. It follows, then, that the two are connected: there must be some relationship between emotions, decisions, and acting upon them.
