(THE COLLEGE FIX) — A recent research paper suggests that preschool teachers are the reason most people identify as heterosexual.

“Reproducing (and Disrupting) Heteronormativity: Gendered Sexual Socialization in Preschool Classrooms,” published last month in the journal Sociology of Education, is based a sociology researcher’s observations of nine different preschool classrooms over the course of 10 months.

Heidi Gansen, a University of Michigan doctoral student whose research interests include gender and sexuality and childhood, concludes that preschool teachers are both constructing and disrupting gendered sexuality in multiple ways.
