In recent decades, there has been a marked increase in the number of people disclosing their LGBTQ identity. We propose a model of a game on a network with social learning to investigate the role of peer effects in coming out with decisions. We use newly collected data from two waves of a spontaneous Twitter coming out campaign to empirically test the prediction that observing peers coming out increases the probability of an individual disclosing their LGBTQ identity. We estimate strong and statistically significant peer effects. We find that spreading information about the campaign through networks does not explain the results. Instead, we argue that these effects are due to changes in beliefs about the costs of disclosure.
