Here are the only two articles I can find mentioning Larry Summers http://www.ams.org/notices/200810/fea-gallian.pdf http://www.ams.org/notices/200810/fea-gallian.pdf http://www.ams.org/notices/201201/rtx120100010p.pdf http://www.ams.org/notices/201201/rtx120100010p.pdf They do not address the question of IQ in any meaningful way.

The question of IQ has more to do with potential candidates rather than success of those candidates.
