Well, from my personal experience:
We have done a whole battery of psychometric tests at work recently, and we also did them when I was still in school. To cut a long story short, I am in a very analytical type of job, and scored near the top of my colleagues in the psychometric testing. This increases management's expectations of me, and I don't cope.

So, I probably have very good analytical skills and above average IQ - yet I am bipolar, and left on my own with my thoughts, I become my own worst enemy. I don't see my analytical skills as beneficial when it comes to dealing with my emotions - it makes it worse.
