Today's lessons is Stocastic Reasonance. This painful concept/theory postulates the idea that more noise does not disguise patterns, but rather makes them more identifiable.
In effect, if you sit at the poker table with little or no regard to how much you are moving, gesturing, talking, etc. the added noise makes it EASIER to pick up tells from you. This seems counterintuitive, as does the opposite postulate that no noise has the same effect.
In order to best disguise our tells, we should keep "noise" to a minimum, but not eliminate it altogether.
Now, go wash your brain out.
