almost everyone who is really interested in chess and can devote a lot of time into chess can achieve the FM title. This naturally excludes people with a very low (or even average) IQ.
50% of the population has an iq of 100 or below, so I don't see how this could be "almost everyone". I would think "almost everyone" would be more like 95-99% no?
as previously posted, I don't think someone who has an average iq will be able to obtain anything higher than ~2000-2100 with 5-10 years of uninterrupted serious chess study and training.

I am not living in US so I don't know anything about that test. I have an IQ of 137 (as previously posted). I have concluded in my post on page 12 that a high IQ is definitely helping to be a good chess player, but hard study is also necessary. If you are not really smart, then you have to study more.
Though, to be a Grandmaster needs a lot of talent and proper education. But I'd still say that almost everyone who is really interested in chess and can devote a lot of time into chess can achieve the FM title. This naturally excludes people with a very low (or even average) IQ.
