How many times a week do you see someone posting a headline to Facebook with a ridiculous scientific claim about your health? '9 out of 10 Doctors Say You Should Stop Exercising,' 'New Report Shows Milk Prevents Cancer,' 'New Study Shows Milk Is Pure Poison, Stop Drinking Milk Or Else Everyone You Know Will Die!' If you're like us, you probably don't even pay attention to them anymore because the results are so fluid and often contradictory. Tell us now– are eggs good for you? You have no idea. Yes, but not the yolks? Who the hell knows anymore?There's a reason why so many studies about human health and behavior are so unpredictable, and you may not be happy with the answer. It's because studying humans is freaking impossible, and that's never going to change. When you're studying people, there's an endless amount of incalculable variables that make reaching a conclusion a futile undertaking. And even if you control for as many factors as you can think of, you still might not be able to account for your subjects' genetics or the very likely chance that they're just lying to you. "Oh, my diet? Yeah, I eat 2 salads a day, no dressing, and a plain cut of grilled chicken for dinner. I definitely didn't drive through McDonalds on the way here and order a #3 with a Dr. Pepper, no pickles."In conclusion, don't trust anything you read or hear ever, or do, because science doesn't really know what it's doing. On this week's episode Cracked editor-in-chief Jack O'Brien is joined by executive editor Jason Pargin (aka David Wong) to talk about how and why science fails us in this regard and why you should probably still be flossing.Also, you can see us on Saturday, October 29th at the Now Hear This podcast festival in Anaheim, California.
