They choose this group under the assumption that these founders would welcome being reached out to for the survey because they had signed up proactively to this email list. There's certainly some room for sampling bias, but not nearly as much as you claim. I also strongly disagree that this is shocking: it's difficult to make good estimates, but various surveys are often in excess of 60% for women: http://www.statisticsviews.com/details/feature/10906109/Sexual-Harassment-Statistics-Is-the-Truth-in-the-Numbers.html http://www.statisticsviews.com/details/feature/10906109/Sexu... 20% is below a reasonable minimum estimate: https://fairygodboss.com/articles/sexual-harassment-statistics https://fairygodboss.com/articles/sexual-harassment-statisti... Now, this is a more specific survey, not just any sexual harassment, but these numbers should not be shocking. One of the core messages of the me-too movement is that these numbers should not be shocking, this is the reality, and ignorance of this can contribute to the problem.
