| Abstract: | Studied the development of overconfidence with regard to answering a general knowledge questionnaire when questions were given with no clues and repeated with 1 to 3 clues. Human subjects: 25 male and female Canadian adults (mean age 30 yrs 2 mo). Ss were given a notebook with 50 questions: all questions appeared 4 times—once with no clues, and 3 times with 1 to 3 clues. Ss were asked to answer the questions and to indicate on a scale of 0.5 to 1 how sure they were of their answers. The results were analyzed statistically according to sex, confidence level, and number of clues, using an analysis of variance (ANOVA).
