Grammar prescriptivists -- who believe rules should be followed; "descriptivists" believe correct grammar is whatever works -- love to appeal to logic. If "he could care less," then he could care less -- you have to say "he couldn't"! It's the rock we cling to against the rising tide of literally-means-figuratively-now. Well, it may be time to loosen that grip, because the evolutionary forces of language extremely do not care.

There's a lot of bad advice, bad science, and bad logic out there -- and I'm sorry to report that some of it is probably coming from people you trust. Sharpen your pencils and take a seat -- Bullshit Resistance School is in session.

Over the last couple of years there have been some significant public debates where the results have defied belief - at least, the beliefs of some people. We've had the Brexit vote, the election of Donald Trump to the US presidency and we are facing a similar debate in Australia over the same-sex marriage vote.

On both sides of all these, and numerous other debates, are two broad schools of argument. And when that happens, there's little chance of a coherent debate.

You're probably reading this on a phone or computer in an English-speaking country. If that's the case, you're not in the majority of people on Earth. This video highlights this unusual perspective.

Why is it that we often ignore hard data and go with our gut when making a decision? It's especially true when it comes to estimating the probability of something. Are our brains just really mediocre when it comes to numbers or is there a reason for our misguided instincts?

It's a stereotype, but many of us have made the assumption that scientists are a bit rigid and less artistic than others. Artists, on the other hand, are often seen as being less rational than the rest of us. Sometimes described as the left side of the brain versus the right side -- or simply logical thinking versus artistic creativity -- the two are often seen as polar opposites.

If you were on Facebook today, there's a pretty good chance you came across this fruit-based brain teaser. The internet is going crazy for it. What seems like a simple maths equation is actually a bit more complex than it first appears. Can you solve it?

We're supposed to be rational, sensible beings that work hard, reap the rewards and let logic guide the way. That's the way the world goes round, but every now and then a small break from sanity can do us some good.

School quizzes occasionally contain a puzzle so fiendish that it even stumps intelligent adults. (Teachers have to get their kicks somehow, y'know.) The above brain-teaser recently appeared on an elementary school entrance exam in Hong Kong and quickly went viral. How long will it take you to solve it?

When you're in an argument, it's only natural to want to explain your position as fast and as often as possible. However, if you want to argue more effectively, ask your opponent to explain their perspective in detail first.
