Novel Association Results for Behavioral Phenotypes: Genome-Wide Association Study; Harvard University, Cambridge, MA, and Union College, Schenectady, NY; July 2007–June 2009

Trait	Reported SNP	Minor Allele	Sample MAF	HapMap MAF	Effect Size	P
Liberal vs conservative	rs10952668	T	.458	.392	.552 (.478)	2 × 10−8 (1 × 10−6)
Gambling frequency	rs1402494	G	.206	.241	.278 (.276)	3 × 10−8 (6 × 10−8)

Note. MAF = minor allele frequency; SNP = single-nucleotide polymorphism. Liberal versus conservative was reported on a 7-point scale. Gambling frequency was reported on a 5-point scale. Effect sizes and P values after adjustment for general cognitive ability, Openness, Neuroticism, and Agreeableness are given parenthetically. Note that effect estimates may be inflated as a result of the winner’s curse.
