 People formulate conspiracy theories to explain, for example, power relations in social groups and the perceived existence of evil forces.Proposed psychological origins of conspiracy theorising include projection; the personal need to explain "a significant event [with] a significant cause;" and the product of various kinds and stages of thought disorder, such as paranoid disposition, ranging in severity to diagnosable mental illnesses.Some people prefer socio-political explanations over the insecurity of encountering random, unpredictable, or otherwise inexplicable events.
