I think Spica is making a common mistake, which I expect the author might also fall into—the need to rationalize everything. Our bodies are not rational.
take a million PCs, use their calculators and you will get consistent equivalent response, our bodies are full of randomness. Sometimes, you eat a favorite fruit and dislike it, while others find it tastes the same as usual. People can love or hate something without knowing why, and they often invent reasons TO FEEL IN CONTROL. But the truth is, we are not always in control.
Also there are various studies on the matter of wether criminal profiler are actually useful...they are not.
