That's really surprising, I thought a high min_dev would have the opposite 
effect -- that scores would be more likely to be close to 0.0 or 1.0.  

I had intuited that a low min_dev would mean that there was more neautral-ish 
tokens that would push the score towards 0.5.  

Am I just confusing myself?
