I watched a demonstration of that principle on the local news in San Diego. They used a big, strapping San Diego cop. He was given a large weight to lift. He did it with a big smile and total ease. Next, they made him look at a large card with the test shade of pink. He couldn't lift the weight. Some autonomic nervous system response caused an involuntary loss of physical strength.

Absolutely right. Some jails paint the cell walls pink to attempt to influence violent offenders. My guess is that the good Professor has a few bets down on the opposing teams...
Nifty! They need to start using this at Gitmo.
There was also a study done that demonstrated that listening to rock music makes you weaker. Weight lifters lost about 1/3 of their ability to lift weights while listening to the Rolling Stones.
