“…Several studies have investigated the relationship between belief in psychic ability and various measures of academic achievement, including participants' course grades, Scholastic Aptitude Test (SAT) scores, exam performance and highest level of educational attainment. Although many of these studies have reported that believers show significantly lower levels of academic performance than disbelievers (Gray, 1987; Messer & Griggs, 1989; Musch & Ehrenberg, 2002; Otis & Alcock, 1982; Pasachoff, Cohen, & Pasachoff, 1970), the overall pattern of results is inconsistent, with some researchers failing to replicate this finding (Thalbourne & Nofi, 1997) and others reporting believers outperforming disbelievers (Emmons & Sobal, 1981; Haraldsson, 1985; Tobacyk, Miller, & Jones, 1984). Studies examining the relationship between belief in psychic ability and scores on intelligence tests have also yielded mixed findings, with some researchers reporting negative correlations (Smith, Foster, & Stovin, 1998), others failing to find this relationship (Thalbourne & Nofi, 1997; Wiseman & Watt, 2002) and, in at least one study, believers obtaining significantly higher scores than disbelievers (Jones, Russell, & Nickel, 1977).…”
