There is voluminous evidence that exclusive reliance on heuristic processing tendencies of Type I sometimes results in suboptimal responding (Baron, 2008; Evans, 2007a; Gilovich, Griffin, & Kahneman, 2002; Johnson-Laird, 2006; Kahneman & Tversky, 1973, 1996, 2000; Koehler & Harvey, 2004; Nickerson, 2004, 2008; Nisbett & Ross, 1980; Tversky & Kahneman, 1974, 1983, 1986) and that such thinking errors are not limited to the laboratory (Ariely, 2008; Åstebro, Jeffrey, & Adomdza, 2007; Baron, 1998; Baron, Bazerman, & Shonk, 2006; Belsky & Gilovich, 1999; Berner & Graber, 2008; Camerer, 2000; Chapman & Elstein, 2000; Croskerry, 2009a, 2009b; Dawes, 2001; Hilton, 2003; Kahneman & Tversky, 2000; Lichtenstein & Slovic, 2006; Lilienfeld, Ammirati, & Landfield, 2009; Myers, 2002; Prentice, 2003; Reyna et al., 2009; Stewart, 2009; Sunstein, 2002, 2005; Taleb, 2001, 2007; Tavris & Aronson, 2007; Tetlock, 2005; Thaler & Sunstein, 2008; Ubel, 2000).
