Oops! U.S. News reports that women are about twice as likely as men to carry credit-card debt:

A 2015 National Debt Relief survey of 1,107 adults with credit card debt revealed some interesting differences between the sexes. In the survey, the main difference between men and women was the amount of credit card debt they carried.

For instance, 63 percent of women ages 18 to 24 carried some credit card debt, but only 36 percent of men in that age category had any debt. Similarly, 66 percent of women ages 55 to 64 carried credit card debt, but only 33 percent of men in that age bracket had credit card debt.

And since the average interest rate on credit cards these days hovers at just under 19 percent, you might conclude that women are twice as dumb as men. Or that they're maybe  twice as likely to be shopaholics, as evolutionary psychologist Daniel Kruger of the University of Minnesota found in a 2009 study:

The idea for Kruger's new study arose from a personal experience. He and his now-wife were traveling with friends through the Czech Republic. When they arrived in Prague, the women immediately wanted to go shopping, an impulse that the men did not understand.

"We thought, 'Why do you want to go shopping? You can go shopping anywhere. There's a thousand years of culture here,'" he said. "They were adamant. They put their foots down. They took the credit cards and left."

That wasn't the end of it. When the women returned, Kruger said, they were full of joy and pride as they showed off their loot, even though many of their purchases came from a chain store that had outlets in other countries.

A "chain store that had outlets in other countries"? Maybe women are dumb and shopaholics!

But of course feminists and the men who love them aren't buying that. They've cooked up a more acceptable reason for the credit-debt gender gap: Sex discrimination.

Although these results could be twisted to affirm harmful gender stereotypes about emotionality versus rationality between the sexes, the survey authors came up with a more sound explanation for debt disparity: sexism

Yep, the fact that women are still making less money than men across the board is more likely the reason women are forced to turn to credit to make ends meet. Although there are a variety of factors, including lack of financial education for women in schools, Adam Tijerina, Consumer Advocate for National Debt Relief, told U.S. News & World Report that the pay gap is probably the driving force behind these debt discrepancies.

Um, even if you believe that women earn 77 cents for every man's dollar, a canard that even liberal women admit isn't true, once you correct for women's preferences in selecting jobs, the idea that women earn only three-fourths as much as men still doesn't account for the fact that they carry twice as much debt.

So, let's see: Women are not only shopaholics but they can't do math. More "harmful gender stereotypes."
