How much do you like classical music?The assumption is that a 3-digit IQ is a prerequisite to enjoying classical, though it need not be sufficient for liking it. Not caring for it does not necessarily indicate a double-digit IQ.
Going in the other direction, I offer this corollary for detecting double-digit IQs:
Do you enjoy scratch-off lottery tickets?The presumption is, similarly, that only a person with a double-digit IQ will enjoy betting for such low stakes paired with such unfavorable odds. This haughty 3-digiter finds it about as attractive a proposition as playing a game of Candy Land in which everyone else draws two cards per turn while I only get to draw one. Give me chess, please, or at least Monopoly.
That's not to say Homer Simpson represents the entire left half of the bell curve, however. Not all people of modest intelligence are going to find scratch-offs fun:
Unfortunately the GSS doesn't query respondents about their attitudes about playing games of chance. Back in the mid-nineties, though, it did ask respondents to express their (dis)agreement with the statement: "The really good things that happen to me are mostly luck". The following table shows the percentages of respondents, by intelligence*, who either "disagreed" or "strongly disagreed":
One might object that those of modest intelligence are indeed assessing things accurately when they report that, relative to their more intelligent neighbors, luck is more often a an explanation for fortune smiling upon them than their own deliberate efforts are.
Perhaps. To the extent this is the case, allow me to offer some friendly advice to scratch-off players: Switch to big game drawings like Powerball or Mega Millions. Yes, the odds are that over the long run you'll come out in the red, but unlike regular purchases of scratch-off tickets, the law of large numbers doesn't quite guarantee it. And if by heaven's graces you turn out to be as lucky as a goof-off, you'll really be able to ride high on the hog for awhile (for awhile, anyway)!
GSS variables used: MOSTLUCK, WORDSUM(0-3)(4-5)(6)(7-8)(9-10), BORN(1)
* Respondents are broken up into five categories that roughly form a normal distribution; Really Smarts (wordsum score of 9-10, comprising 13% of the population), Pretty Smarts (7-8, 26%), Normals (6, 22%), Pretty Dumbs (4-5, 27%), and Real Dumbs (0-3, 12%)
