This study explores the origins of individual differences in impulsive buying from a behavioral genetics perspective. It also assesses whether phenotypic associations between personality and impulsive buying tendency can be attributed to overlapping genetic factors. Data were collected via mail for 339 twin pairs. Personality traits according to a five-factor model and impulsive buying were measured. The results indicate that additive genetic, shared environmental, and nonshared environmental influences may be important for individual differences in impulsive buying. Phenotypic correlations with Impulsivity (r = .32), Neuroticism (r = .23), and Extraversion (r = .20) are largely driven by the overlapping genetic influences. Together with age and sex personality traits explain 25% of individual differences in impulsive buying tendency. These results add to our understanding of individual differences in impulsive buying and the nature of its relationship with personality.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

AbstractUsing a genetically informative design (about 2000 twin pairs), we investigated the phenotypic and genetic and environmental architecture of a broad construct of conscientiousness (including conscientiousness per se, effortful control, self-control, and grit). These four different measures were substantially correlated; the coefficients ranged from 0.74 (0.72–0.76) to 0.79 (0.76–0.80). Univariate genetic analyses revealed that individual differences in conscientiousness measures were moderately attributable to additive genetic factors, to an extent ranging from 62 (58–65) to 64% (61–67%); we obtained no evidence that shared environmental influences were observed. Multivariate genetic analyses showed that for the four measures used to assess conscientiousness, genetic correlations were stronger than the corresponding non-shared environmental correlations, and that a latent common factor accounted for over 84% of the genetic variance. Our findings suggest that individual differences in the four measures of conscientiousness are not distinguishable at both the phenotypic and behavioural genetic levels, and that the overlap was substantially attributable to genetic factors.
