I posted something like this a little over a year ago in a rather contentious thread. Interest in this sort of thing came up again more recently in another thread, and a suggestion was made to organize such a table by ability score modifier. Here's the result:
[TABLE="width: 790, align: left"]
[TR]
[TD]Score (frequency using 'averaging' dice +1)[/TD]
[TD="align: center"]Bonus[/TD]
[TD="align: center"]Range of Deviation IQ[/TD]
[TD="align: center"]Fantasy Rating[/TD]
[/TR]
[TR]
[TD]1 (0.00%)[/TD]
[TD="align: center"]-5[/TD]
[TD="align: center"]1-10[/TD]
[TD="align: center"]'Non'-intelligent or not ratable[/TD]
[/TR]

[TD="align: center"]10-28[/TD]
[TD="align: center"]'Animal' intelligence[/TD]
[/TR]
[TR]
[TD]4-5 (0.00%)[/TD]
[TD="align: center"]-3[/TD]
[TD="align: center"]28-46[/TD]
[TD="align: center"]Semi-intelligent[/TD]
[/TR]
[TR]

[TR]

[/TR]
[TR]
[TD]14-15 (11.11%)[/TD]
[TD="align: center"]+2[/TD]
[TD="align: center"]118-136[/TD]

[TD="align: center"]+3[/TD]
[TD="align: center"]136-154[/TD]
[TD="align: center"]Genius intelligence[/TD]
[/TR]
[TR]
[TD]18-19 (0.00%)[/TD]
[TD="align: center"]+4[/TD]
[TD="align: center"]154-172[/TD]
[TD="align: center"]Supra-genius intelligence[/TD]
[/TR]
[TR]
[TD]20+ (0.00%)[/TD]
[TD="align: center"]+5 or more[/TD]
[TD="align: center"]172+[/TD]
[TD="align: center"]Godlike intelligence[/TD]
[/TR]
[TR]
[TD="align: center"][/TD]
[TD="align: center"][/TD]
[TD="align: center"][/TD]
[TD="align: center"][/TD]
[/TR]
[/TABLE]
The table is designed for a population with scores generated using the 'averaging' method rather than 3d6, which I believe was always a method for generating exceptional rather than general characters. The ratings come from or are inspired by those which appear in the original Monster Manual (1977) and the Stanford-Binet (1916) classification, which I believe was in part the inspiration for Gygax's ratings, being the only IQ classification ever to use the term 'genius'.
My posting this here in no way implies that I believe that PC ability scores should be used to limit the action declarations of players, but it is my hope that such a table can be helpful, especially to DMs when deciding the actions of monsters as is the apparent intent of the original table in the MM (1977).
