Putting a Finger on the Problem

Researchers at the University of Alberta came out with a study that says the relative length of your index finger compared with your ring finger might predict how physically aggressive you are (is this a result of pressure to come up with a research output for tewnure track faculty? :) ). That is, the shorter the index finger is compared to your ring finger the more physically aggressive you are. I suppose I can wave my hand at a mugger and say "see that? do you know what you're dealing with here?"
