With over 1500 responses, more than 60% of respondents reported some diagnosis for mental illness, with almost one in four respondents mentioning depression in particular. There is substantial co-morbidity between depression and the various anxiety disorders, as there are among the anxiety disorders, so, e.g., the 24% that report depression may also include some of the 5% that checked social anxiety disorder or the 4% that chose OCD. I assume in a poll like this, people are not so perverse as to vote "strategically" or otherwise try to muck up the results. So I think we can conclude from this that the majority of faculty and students in philosophy have confronted some kind of mental illness in their lives. I've opened comments if readers have other thoughts about these sobering results.
