You should check out starting strength by marc rippetoe.
He actually teaches the Low bar squat with with the head looking down about 6-10ft(approx.) in front of you. He explains the reason for this.
So, it isn't necessarily popular teaching to look up and your intuition serves you well.
P.S. If you haven't read starting strength you would probably enjoy it. The exercise instruction is top notch.
"The fastest way to get strong muscles is also the fastest way to make them bigger. We know what works best to make them strong in the shortest time possible. If you want to get big, do the thing that makes them strong." - Marc Rippetoe

I am not a powerlifter nor am I a bodybuilder. I just want to be big and strong.
