The Science of Twerking

It seems that the twerking trend simply won't die. But why?

What about this bizarre dance craze is so fascinating? First, let's get clear on what twerking is:

Twerking: v When a dancer shakes her hips in an up-and-down bouncing motion, causing the dancers buttocks to shake, wobble, and jiggle (Thank you, Wikipedia.)

The question is why do people go so crazy over twerking?

We can use science to understand why this trend has caught on. In fact, there are scientific reasons why our brain can't stop watching those twerking Youtube videos. Let me show you the 3 scientific principles behind the twerk.

The 3 Scientific Principles of Twerking

1. Shape Shifting

Men love the roundness of a woman's body. The only thing they love more than the roundness of a woman's rump is the jiggling of a woman's rump -- and twerking showcases both.

2. Babies Anyone?

Twerking puts a woman in the prime mating position. (Yes, you know the one I mean.) So instinctively men and women know that canine style stance is great for making babies.

3. What the What!?

Our brains love seeing unusual and bizarre things. Twerking is definitely not... something we normally see. So watching someone twerk is like eating a new delicacy or trying a new adventure -- our brains love the novelty.

Science is a fun way to try to understand the psychology behind the latest trends... now you have a scientific excuse to keep hitting the replay button on those twerking demos.
