Dogs are like people: Often the prettier you are the dumber you also are

In doing research about the Westminster dog show, I came across an interesting argument that makes perfect sense. For thousands of years as dogs were becoming domesticated, they were bred to be smart, to have strength and good instincts. But as dogs started to become bred for looks instead of brains, they have become dumber and dumber. And it makes sense, these dogs exist outside the natural order of evolution; in the wild the dumb dogs would die before they got a chance to reproduce. These dumb dogs have less personality and are harder to train, which seems a bit counter-productive to the objective of the show.

So heres something to think about: don't humans have the same problem? Intellectuals are less likely to reproduce, passing on their genius genes. The crazy nerdy guy may have gotten a 780 math SAT but he will often have more trouble reproducing, while the ditsy girl who drops out of school may have a half dozen kids before she turns 30. Scientists do believe that with every generation humans are becoming dumber and dumber.

So if you're dumb don't have kids- you'll be saving humanity.
