The Truth Behind Myths and Misconceptions

The Truth Behind Myths and Misconceptions

There are tons of everyday science myths we allow to dictate our behavior without even knowing it. News flash: Toilets don't flush differently depending on what hemisphere you're in. Nor will you catch a cold just because you left the house in dead winter with a head of wet hair. These common myths, often staunchly defended, are the rules many have been taught to live by. And they've all been debunked.

How much crueler can fate be, you ask? Well, cats don't really have nine lives, and there is no actual stairway to heaven. But in all seriousness, how did these pervasive myths rise in popularity? How did they withstand the test of time, and why can't we stop believing them? Most start as facts that get slightly twisted over time (for example, carrots are great for eye health, but don't actually improve vision). Get ready to have your world shattered as this playlist puts the science behind common misconceptions.
