Predicting belief in paranormal phenomena: a comparison of conditional and probabilistic reasoning

Previous studies, using student participants, have investigated conditional reasoning (Wierzbicki, 1985) and probabilistic reasoning (Blackmore and Troscianko, 1985) separately as predictors of belief in paranormal phenomena. Findings show that the fewer reasoning errors made, the less likely people are to believe. The current study investigated both types of reasoning within the same analysis in order to find the extent to which each would predict paranormal belief by itself. Sixty‐five non‐undergraduate participants completed two self‐report questionnaires to ascertain their degree of belief in the paranormal, and a reasoning test. The expected negative correlation between reasoning ability and paranormal belief was found. However, while conditional reasoning scores predicted paranormal belief (r=−0.27), probabilistic reasoning scores did not (r=0.01). It was noted that the sample used was possibly biased, due to a lack of sufficiently sceptical participants, and that future studies may need to target people with different degrees of belief.

Social roles and the moral judgement of acts and omissions

Three experiments investigated how moral judgements of harmful acts and omissions are affected by information about social roles. Subjects were given vignettes in which the relationship between an actor and victim was varied along the dimensions of solidarity (e.g. friends versus strangers) and hierachy (e.g. superior versus equal; the terms are from Hamilton & Sanders, 1981). Subjects were asked to judge the morality of the actor in each case, both for a harmful omission (e.g. intentionally withholding the truth) and for an equivalent act (e.g. actively lying). Subjects judged the behaviour worse in the act than the omission. Judgements were also affected by role relationships. The act–omission difference was also greater in the low-responsibility roles. Responses to the high-responsibility roles seem to reflect in a consequentialist perspective, focusing on outcomes rather than prohibitions.
