Abstract
We are conducting a large scale field experiment where we randomly assign desk mates in Hungarian schools. Our main outcome variables are confidence, prejudice, and preferences for mixed gender teams. In this plan we pre-register some key decisions to follow once we receive the data.

Interventions
Intervention(s)
We are conducting a large scale field experiment where we randomly assign desk mates in Hungarian schools. Male students are thereby randomly assigned to female students and vice versa.
