"Environmental Influence on Emotional and Cognitive Abilities Trumps Genetic Factors"

A study involving twins suggests that environmental factors may have a greater impact on certain cognitive abilities, such as metacognition and mentalizing, than genetics. Twins raised in similar educational and socio-economic environments displayed similar cognitive traits, challenging previous beliefs about the heritability of these skills. The findings highlight the crucial role of family environment in shaping cognitive abilities and suggest that metacognition and mentalizing are more influenced by environmental factors than genetics.
