The results of a controversial new study by researcher Satoshi Kanazawa of the London School of Economics state that intelligent women do not feel the maternal urge, according to The Guardian.

Kanazawa found that women's maternal urge declines by 25 percent for every 15 additional IQ points. This led the researchers to the controversial conclusion that smart women do not have babies. It should come as no surprise to learn that such a bold claim has not been met with cheers.

Whether or not Kanazawa's findings are true, evidence certainly exists to support his claims. According to 2008 data from the Pew Research Center, childlessness was most common among women with advanced degrees. For example, 24 percent of women between the ages of 40 and 44 who held a bachelor's degree also had yet to have a child.

Not every woman - or man - may pay much attention to this study. However, if women with or without children are curious to see how intelligent they actually are, they can always take an IQ test.
