Oh, that's nothing. A couple of years back, we had a FReeper who claimed to have an IQ of 170. This same FReeper lost a $40,000 civil case, countersued the State of Washington for $15 million for being in collusion with the winning side based solely on a "knowing look", and predictably lost every appeal. He then tried to make a citizens' arrest against state Supreme Court Justice CJ Alexander, on RICO charges for not hearing his final appeal.
Let's just say that IQ numbers aren't all they're cracked up to be.
True, but this was on the UK scale, different from the US scale.
My experience is the higher the IQ the less stable, but that’s for very high IQ’s.
