“…Researchers have made substantial improvements in understanding the relationship between various measures of cognitive ability and economic behavior in different domains. In this respect, measures of cognitive ability have been shown to determine the degree of strategic sophistication (e.g., Rydval et al, 2009 ; Brañas-Garza et al, 2012 ; Carpenter et al, 2013 ) and appear to correlate with risk and time preferences (Frederick, 2005 ; Brañas-Garza et al, 2008 ; Burks et al, 2009 ; Dohmen et al, 2010 ; Andersson et al, 2013 ; Benjamin et al, 2013 ), as well as with heuristics and well-known behavioral biases in financial decisions, such as overconfidence, anchoring or the so-called conjunction fallacy (Oechssler et al, 2009 ; Bergman et al, 2010 ; Hoppe and Kusterer, 2011 ; Toplak et al, 2011 ).…”
