"I introduced my AP Physics students to power posing last spring. One student in particular was always so nervous during assessments and therefore her test scores did not represent her abilities at all. We all know that old saying about correlation and causation — and this was no scientific study — but from that day forward that student power posed before every physics test and her grades went from high 'C's and low 'B's to where she belonged — in the mid to lower 'A's. I'm convinced that power posing helped her even if it is difficult to prove."
