I just found the following entry while reading my RSS feed of my favorite blogs; this is from Paul Kedrosky's personal business blog:
Crazy-fun new study in press at the journal Intelligence. It attempts to puzzle out the connection between IQ and wealth, only to come up with the entertaining -- if unsurprising -- result: There isn't one. Bad news for brainy geeks everywhere.
While it doesn't stand up to statistical scrutiny, an eyeball check of the above figure does make it look like there is a soft inverse relationship. In other words, maybe we should be accusing random foolish sorts among us of being smarter than they're acting: Hey, if you're so dumb, how come you're not rich?!
These type of studies get us all thinking, or not...
