The conjunction fallacy describes how people are more likely to think two events occur together than that either individual event occurs separately. Conjunction fallacy is a theory that assumes people are more willing to take risks so as to avoid losses than to achieve gains. It occurs when we assume specific conditions are more probable than a single one.
