Over ancestral time, men had more paternity uncertainty than women. If the father and his offspring have similar facial features, the former is more confident of his paternity and he, therefore, tends to invest more resources in the child. In 158 dyads of adolescents (i.e., teenagers) and their fathers, we tested—using actor-partner interdependence modeling (APIM)—the relationship between facial resemblance and personality similarity on the one hand and paternal investment (i.e., emotional and financial) on the other hand. We also examined how important personality (i.e., emotionality, psychopathy, narcissism, and Machiavellianism) similarity is in predicting paternal investment controlling for facial resemblance. Both facial and personality resemblance were associated with paternal investment. We also found that personality similarity accounts for incrementally more variance in paternal investment over facial resemblance. Additionally, we found that psychopathy moderated the relationship between facial resemblance and paternal investment.

Fathers high in psychopathy invest more in offspring who resemble them

Abstract

Over ancestral time, men had more paternity uncertainty than women. If the father and his offspring have similar facial features, the former is more confident of his paternity and he, therefore, tends to invest more resources in the child. In 158 dyads of adolescents (i.e., teenagers) and their fathers, we tested—using actor-partner interdependence modeling (APIM)—the relationship between facial resemblance and personality similarity on the one hand and paternal investment (i.e., emotional and financial) on the other hand. We also examined how important personality (i.e., emotionality, psychopathy, narcissism, and Machiavellianism) similarity is in predicting paternal investment controlling for facial resemblance. Both facial and personality resemblance were associated with paternal investment. We also found that personality similarity accounts for incrementally more variance in paternal investment over facial resemblance. Additionally, we found that psychopathy moderated the relationship between facial resemblance and paternal investment.
