Now we read that Meg Whitman spent at least $85 million to win the Republican nomination for Governor in California. She presumably will spend even more in the general election campaign.
Now Whitman is a billionaire supposedly, so I suppose that this is not much to her. But the question I want to ask is can she not find a better use for this money? What about charity? She could give this to the Gates Foundation, for example, and improve health around the world. Or if she is only concerned with California, then to some California charities.
To choose spending this on her campaign, she has to believe that she is better for California than the next best candidate by more than the value of the charitable contributions. Now most politicians hardly ever make a difference. So she must have a really, really, big ego.
The question then is whether you really want as a Governor someone who is so sure they are great. It seems to me that politicians who self-finance their campaigns are super egotists. The fact that they spend their own money demonstrates their confidence, but it also demonstrates something about them.
Or it could be that they do it just to show off. They want to be powerful in and of itself.
Now some researchers have looked at this by studying students who took College Admissions tests while in the seventh grade -- obviously high achievers.
So it is possible for men and women to achieve the same mean scores on math tests yet persistent differences to appear when one looks at the variance. But Harvard presumably only hires scientists from the upper tail, not the lower one.
The Duke researchers — Jonathan Wai, Megan Cacchio, Martha Putallaz and Matthew C. Makel — focused on the extreme right tail of the distribution curve: people ranking in the top 0.01 percent of the general population, which for a seventh grader means scoring above 700 on the SAT math test. In the early 1980s, there were 13 boys for every girl in that group, but by 1991 the gender gap had narrowed to four to one, presumably because of sociocultural factors like encouragement and instruction in math offered to girls.
Since then, however, the math gender gap hasn’t narrowed, despite the continuing programs to encourage girls. The Duke researchers report that there are still four boys for every girl at the extreme right tail of the scores for the SAT math test. The boy-girl ratio has also remained fairly constant, at about three to one, at the right tail of the ACT tests of both math and science reasoning. Among the 19 students who got a perfect score on the ACT science test in the past two decades, 18 were boys.
Meanwhile, the seventh-grade girls outnumbered the boys at the right tail of tests measuring verbal reasoning and writing ability. The Duke researchers report in Intelligence, “Our data clearly show that there are sex differences in cognitive abilities in the extreme right tail, with some favoring males and some favoring females.”
Wonder if any of Summers' critics will apologize?
