Today while visiting the tiger exhibit at my local zoo, I read that in areas where tiger attacks on humans are common, people will often wear a mask on the back of their head to ward of tiger attacks, as tigers only ever attack from behind.
Wikipedia makes the unreferenced claim that this strategy used to work, but no longer does because tigers are too clever.
Is there any evidence to show that wearing a mask on the back of one's head is, or ever has been, effective in warding off tiger attacks?
This worked for a short time, but the tigers quickly realized it was a hoaxWell, we need more tigers on Skeptics! – Yannis May 3 '12 at 6:49
