I've always thought it also gives a number of other impressions too and isn't at all reliable. It can make people look nervous and uncomfortable as they're essentially fidgeting. It can also make people look like they've got a hyperactivity disorder too because they can't stand still for 10 seconds.

Ok, so... Staying on the line of PUA myths, thoughts on tests for these things? Ideally tests need to offer as little room for argument as possible. Obviously testing in the field is good but what's available to us to avoid counter argument? What arguments are most likely so I can build around them to try and avoid them occurring.. Obviously "British girls are easy" isn't going to be an easy one to avoid without a bit of flying.
