If this is true, then I guess all us slaves to our conditioning had better hope that the conditioning is good conditioning! Now that the vast majority of readers are feeling suitably outraged, it is time to present the ‘Levitt Equation’. I stress that this equation is subject to a number of reservations and should not be taken too seriously.
The Levitt Equation
Elo ~ (10 x IQ) + 1000
The meaning of the ‘~’ symbol can be taken as ‘given many years of intense effort, will tend to equal approximately’. That is to say that a player with an IQ of Y, after many years of tournament play and study will tend to have a chess Elo rating of about 10Y + 1000.
It is easy enough to translate this into
British Chess Federation (BCF) grades, should anybody prefer to use the English system rather than the international one. Using the standard conversion:
Elo = 8 x BCF + 600
and combining this with the ‘Levitt Equation’, one gets (after some basic algebra):
BCF ~ (1.25 x IQ) + 50
