Are jokesters screwing up data on gay teenagers?

Teens are mischievous, not to be trusted. You’ve probably heard the trope before – maybe you even believe it yourself. But is the stereotype now warping our trust of scientific results?
Surveys can help researchers better understand the lives of teens, but skeptics argue that youth are often dishonest and that the results cannot be trusted.
This idea led into a study published a few years ago, which called into question over a decade of research on the health and well-being of lesbian, gay and bisexual (LGB) youth.
In a new study, we challenged this idea with our own search for jokesters in this data. We discovered that more than 98 percent of youth told the truth on self-report surveys. We also found that LGB youth were not any more likely than heterosexual youth to provide mischievous responses.
