On the false ontological consensus

The objective of the research was to check whether False Consensus Effect (FCE), shown in much research, is also valid for ontological decisions. Test participants, faced with an ontological dilemma, made a choice three times, which of the 3 item set (Cracow City, Me myself, the Universe) refers to something most real. The research conducted first among psychology students (N=116), then replicated on mathematics students (N=126) and middle-aged people (N=106). Results: 1) All groups chose the Universe most seldom (4%-11% subjects), the remaining two “objects” were chosen with similar frequency, 2) FCE occurred in all groups and in reference to each choice, 3) with people who made inconsequent choices (16% of test participants), FCE was notably higher (p <.001) in comparison to people making consequent choices, 4) FCE with inconsequent people turned out to be higher (p <.01) even in comparison with “the smallest minority”, people who (consequently) chose the Universe.
