It's quite easily right at the top of the list. In fact, the scientific method is designed precisely to answer it. Rigorously following a procedure involving observation, hypothesis and tightly-controlled experimentation is what separates science from all other disciplines. OK, you ask, so what's the question?

Surely, somebody can stop the most egregious offenders from spreading health misinformation that hurts or kills people, right? Actually, no, not in a free society. The only solution to fake news is better news.
Facebook, a site from which a substantial number of people acquire their daily news, has decided that pages that post fake stories will be banned from advertising. That's a perfectly fine decision, but it raises a bigger and more profound question: Who decides which news is fake? Mark Zuckerberg?
"Fake news" has become a meme — and it's all over the Internet. For example, take a look at a site that claims to provide real evidence that aspartame is carcinogenic in humans.

Yet, many people in a democracy believe the latter. And it leads to a very bad outcome.
Our resident pediatrician always advises us not to be fooled by the cuteness. New research analyzed science reporting in newspapers, the results aren't pretty. Beware of shiny-object syndrome!
No matter the evidence, some people always will refuse to accept it. Some of those people are university professors, like Joel Moskowitz, who is on a crusade to prove that California is secretly hiding data that shows cell phones are giving people cancer.
Politics makes utter fools out of otherwise rational people. The vitriol aimed at President George W.

Pundits subsequently seized upon the terms "Obama Derangement Syndrome" and "Trump Derangement Syndrome."
Since “fake news” seems to be the current buzz-worthy expression, let's point out that we don't have to look very far to find common medical falsehoods that originate in the Land of Celebrity. Like bubble-headed actresses who get attention for no good reason, here are some phony claims that lead the way.
