Bad faith
In philosophy, after Jean-Paul Sartre's analysis of the concepts of self-deception and bad faith, bad faith has been examined in specialized fields as it pertains to self-deception as two semi-independently acting minds within one mind, with one deceiving the other. Bad faith may be viewed in some cases to not involve deception, as in some kinds of hypochondria with actual physical manifestations. There is a question about the truth or falsity of statements made in bad faith self-deception; for example, if a hypochondriac makes a complaint about their psychosomatic condition, is it true or false?
