Abstract: A considerable proportion of the population in post-industrial societies experiences substantial difficulties in the domain of mating. The current research attempted to estimate the prevalence rate of poor mating performance and to identify some of its predictors. Two independent studies, which employed a total of 1,358 Greek-speaking men and women, found that about 40% of the participants experienced poor performance in either starting or keeping an intimate relationship, or in both areas. Furthermore, emotional intelligence, Dark Triad traits, jealousy, and attachment style were found to be significant predictors of mating performance. In particular, higher emotional intelligence and narcissism were associated with higher performance in mating, while higher psychopathy, jealousy and an avoidant attachment style were associated with lower mating performance.
