Thanks for the link.

For me, the most interesting thing is that Lantz doesn't appear to be retarded [1], and yet it was a huge shock for him to find out as an adult that it was possible to think about the odds of a decision being right rather than assuming that decisions were absolutely right or wrong.

I have no doubt that my description of needing years to assimilate the idea that people are really different from each other without this necessarily indicating something the matter with any of them is equally shocking to people who've been vividly aware of psychological differences as long as they can remember. Or I could be wrong-- the variation in clue distribution might be one of the things such people are apt to be clear about.

[1] He actually seems pretty smart-- but "doesn't appear to be retarded" is the only way I can think of to adequately express my surprise that it took him so long to acquire that particular clue.
