Social Comparison Orientation in Monozygotic and Dizygotic Twins [PDF]
Twin Research and Human Genetics, 2017 Twin research has offered evidence that monozygotic (MZ) twins are more socially close than dizygotic (DZ) twins, but has not paid much attention to the way twins compare themselves with their co-twin. The few studies in this area suggest that ‘horizontal comparisons’ (social comparison motivated by solidarity or communion with others) matter more for ...
