Peer deeply into my eyes...
Apparently, when someone goes all slack jaw and blank while staring and thinking at the flop, this is an indication that they are an expert. Not because of what it accomplishes, but because why it happens. "Change Blindness" and other psychological indicators are physically apparent. This also give credence to tells "when there are no tells".
It also seems to that by emulating that behavior, you are more likely to pick up the "affect of the effect". i.e. Some of the reason this is done should rub off. Although the more you know, the smaller the gap.
