Although there exists no universally accepted definitions of causality, it is widely assumed that causal beliefs are essential for human comprehension. The notion of causality is inherent in the very nature of human cognition because knowledge about events implies, among other things, the belief that all events have causes (Noordman & Vonk, 1998). People frequently use rules to assess cause and effect and thus to interpret reality. These rules are applied both in the context of science and in daily life.
