The findings in the article Where Do Cultural Tastes Come From? Genes, Environments, or Experiences in the journal Sociological Science are:
“family background explains more than half of the total variance in cultural tastes and participation and in omnivorousness. Moreover, family background operates mainly via shared genes, with shared environments shaping cultural tastes to some extent, but not cultural participation.”
“MZ (monozygotic) twins are more similar than DZ (dizygotic) twins are with regard to cultural tastes, participation, and omnivorousness in music and reading.”
