Interracial Dating Paper FAQ

sebjenseb • 196 implied HN points • 10 Feb 24
🔬 Science Research Genetics Data Analysis Psychology Relationships
  1. Assortative mating occurs between races, with individuals who date outside their race being more similar to each other in terms of intelligence, height, and risk-taking behaviors.
  2. Current literature suggests that interracial relationships may have a higher likelihood of ending or experiencing domestic violence issues, and mixed-race children might be more prone to mental/behavioral problems, possibly due to self-selection rather than social factors.
  3. Attractiveness was a weak predictor of interracial dating across all races, indicating that mate value or race exchanges based on mate value were not significant factors in interracial dating.
