After problem-solving validity resolving differences opinion rules has been discussed, their conventional real-life arguers is demonstrated. Startin...

The present research investigated the effects of culture-specific theories of change in two related gambling fallacies: the gambler's fallacy (GF; the belief that one is due for a win after a run of losses) and the hot-han...

Furthermore,...
