Mentalism is a branch of psychology that studies the mind and how it works. Mentalists look at things like how people think, how they behave, why they make certain decisions, and more. They also help people better understand their own minds and emotions. Mentalists use a variety of techniques, including talking with people, doing tests, and looking at brain scans, to help people understand themselves better. Mentalism is about understanding people and helping them to become healthier and more successful in life.
