Kahneman uses this chapter to illustrate how intuition works in professionals. While experts are capable of deriving logical explanations in complicated situations, there is a measure of intuitions, or guts as he calls it, that also go a long way to enabling them to make decisions. Such professionals include (but are not limited to) artists and technical personnel. Artists, for instance, can easily tell that an artifact is not genuine without necessarily telling how they came into that conclusion. Human instincts, to a great extent, play a significant role in making sound decisions. Such intuitions collaborate with one’s skills and knowledge to enable a person to derive a relationship or even sense danger. Intuitions, as we find in this chapter, grow with time and experience, and become more validated and reliable as one asserts them to be true especially after an occurrence.
