Gamblers fallacy...

The gambler's fallacy, also known as the Monte Carlo
fallacy or the fallacy of the maturity of chances, is
the mistaken belief that, if something happens more
frequently than normal during some period, it will
happen less frequently in the future, or that, if
something happens less frequently than normal
during some period, it will happen more frequently in
the future (presumably as a means of balancing nature).
In situations where what is being observed is truly
random This belief, though appealing to the human mind, is false.
