The problem is that it's much easier to apply knowledge about biases to dismiss people who disagree with you as biased then to apply knowledge about math to...I'm not even sure what the analogous thing you're thinking about is.
What's the evidence that knowing about cognitive biases is more dangerous than knowing math? My claim is that it is just as easy to apply math in an unbalanced way that favors one's already-held beliefs as it is to apply cognitive biases in a similarly unbalanced way.
In other words, why did EY speak specifically to cognitive biases as opposed to the general problem of using your knowledge more vigilantly to attack others arguments than to attack your own arguments?
