Good points. I have some of the same concerns. It's one of the more thorough screeners I've seen on the internet, but there is a lot of interpretation of even the best tests that a computer just can't do. My MMPI says that I'm probably a psychotic drug addict with mood and personality disorders. I'm not psychotic and haven't ever used drugs. The compouter doesn't know that though. You have to look at information like this in context, and even when it says it isn't for diagnostic purposes, why else are most people going to take a test like this?

I also thought if it's a test of Sanity, a higher score ought to indicate healthier, and catchy titles definitely can be misleading.
