feingold

• Attractiveness correlated with longevity
• Romantic couples who stayed together were often matched in atttractiveness
• This was also seen in friends but stronger in male pairs than female pairs

  May be more important for social balance or avoiding competition
• Socially sensitive– may cause outrage – may result in a lack of funding- as the modern day would also include homosexual couples which this study did not – ingnoring big part of the population

  Protection from harm
• Culturally bias – doesn’t take into account strongly religious cultures and arranged marriage

  principles of science, replicable and falsifiable - not all
• fatalistic as application in the real-world as longevity would only occur due to the same attraction level.

  correlational so cant establish cause and effect therefore low internal validity

  helps us understand both platonic and romantic relationships
