OK,
In all seriousness, let's not be irresponsible to people that may think that this thread is completely serious and are starting out on their trading careers.
While I do not believe that intelligence is necessarily a correlator to trading prowess, I do believe that
technique and attention to detail is.
Also, we should distinguish between trading intelligence, and intelligence to be able to come up with models that work.
I have found without exception that, most winning traders have parents or mentors that are successful traders. The ones that have figured out on their own have gone through a great deal of trial and error, blown a few accounts, and hit upon a technique that works only through herculean perseverance and/or luck.
Jose Raul Capablanca,

the great Cuban World Chess Champion and perhaps the most natural chess player in the history of the world, was once asked if it took any great intelligence to play chess at high levels (believed to be a measure of great intellect). His answer was a resounding NO.
That is my .02 on the subject.
