N1 - Funding Information:
The reported data were collected as part of the second author's Master's thesis who had received a small internal CASA grant to help defray the costs. Gil Greengross worked on this project while serving as a postdoc at Concordia University under the tutelage of the first author (funded via the CURC chaired professorship held by the first author). This work was presented at the Sixth Annual Graduate Research Exposition (John Molson School of Business), the 2014 Association for Consumer Research Conference, and the 10th Biennial Behavioral Decision Research in Management Conference.

N2 - Using a twin study paradigm, the genetic basis of decision making styles was explored using psychometric scales as well as actual choices. Study 1 compared monozygotic (MZ) and dizygotic (DZ) twins along the General Decision Making Scale (GDMS) and the Maximizing-Satisficing Inventory (MAX). MZ twins exhibited greater similarity than their DZ counterparts in terms of their overall GDMS scores, three of the GDMS subscales, and the MAX inventory. Study 2 measured key information processing metrics of actual choices that individuals made via a computerized informational display board. MZ twins are more similar to one another than DZ twins when it comes to the extent of information search prior to making a choice. There were no differences between the two groups of twins in terms of the selectivity and pattern of searches. The results of the two studies suggest that individuals' decision making styles are in part shaped by their genes.
