it is critical to assess positive, competent functioning and not solely the absence of negative outcomes. Indeed, in their recent review, Belsky and Pluess25 noted only one study31 that explicitly evaluated whether genetically susceptible individuals (adults with allelic variation in 5-HTTLPR) reacted to the environmental contexts (early family risk) in a ‘for better and worse' fashion. Taylor et al.31 found both increased risk for negative outcomes under adverse conditions, as well as enriched outcomes under supportive conditions.
