Insight and the selection of ideas.
Neuroscience and biobehavioral reviews October 1, 2023 Ruben E Laukkonen, Margaret Webb, Carola Salvi et al.
Feelings of insight help people select ideas from the stream of consciousness by capturing attention and generating intuitive confidence, enabling fast action under uncertainty. This 'Eureka heuristic' is explained through active inference: implicit restructuring via Bayesian reduction produces a higher-order prediction error (the content of insight), while dopaminergic precision-weighting of that error accounts for the confidence, pleasure, and attentional capture (the feeling of insight). The account aligns with the phenomenology, accuracy, and neural unfolding of insight, as well as its effects on belief and decision-making. Dangers include the formation and entrenchment of false beliefs and vulnerability of insights under psychoactive substances and misinformation.
