Just How Logical Are You? Try This Test

Humans are notorious for overestimating themselves. We think of ourselves as more beautiful, more popular, and better at estimating risk than we really are. Oh, and we probably overestimate our capacity for logic, too.

Brian Gallagher at Nautilus takes on the research of the late psychologist Peter Watson in a new article, exploring the “Watson selection task,” a famous and oft-repeated experimental method that tests subjects’ logical reasoning processes.

In the test, Watson showed a volunteer four cards, two showing numbers, and two colored cards without numbers. He then asked them how they would go about, in the least number of steps, proving whether or not even numbered cards always have a blue face on the back. Though he thought the test “deceptively easy,” as he wrote in a paper on it, 90 percent of his subjects got it wrong. Subjects even admitted that if they had to do it over, they’d probably still choose wrong—highlighting the irrationality of humans.

Years later, psychologist Daniel Kahneman hypothesized that the difficulty of the task has to do with a battle between two cognitive systems triggered by the word choices of the question. One system tends to take mental shortcuts, because it’s faster and easier, while abstract reasoning, the second system, is harder.

We won't spoil just how those mental shortcuts function in this case. Play the game through the YouTube video below, then head over to Nautilus for a deeper explanation of why you probably got it wrong.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

These “Wonder Women” Bingo Cards Feature Amelia Earhart, Greta Thunberg, and 46 Other Inspiring Icons

You could even shout "Wonder Women!" instead of "Bingo!" if you want.

The original numbered version of bingo dates back to 16th-century Italy, but gamemakers have recently begun to realize that there’s no reason the classic game has to be quite so classic. Now, instead of numbers, you can find cards with pretty much any set of images or words you can think of (or you can simply make your own online).

This edition from Laurence King Publishing features illustrations of 48 incredible women who all, in some way, embody the name of the set: Wonder Women. There are sports champions like gymnast Simone Biles and tennis player Serena Williams alongside young living legends like climate change activist Greta Thunberg and education activist Malala Yousafzai. While you might recognize many of the names from history classes—Amelia Earhart and Rosa Parks, for example—or your own iTunes library (yes, Beyoncé is part of this game), others may be unfamiliar. Did you know about Russian cosmonaut Valentina Tereshkova, the first woman in space?

In other words, Wonder Women Bingo is a great way to celebrate your favorite trailblazers and get introduced to some new ones, too. And since the rules are simple—just pick a chip and see if your card has an image to match—it can also double as a learning opportunity for kids.

The illustrations were created by artist Laura Bernard.Laurence King Publishing/Amazon

The game is available for $35 on Amazon and $20 on Laurence King Publishing's website (though it's currently unavailable on Laurence King's site). And if bingo isn’t really your thing (or even if it is), there’s a Fantastic Women card game available for $13 on Amazon, where players try to top each other’s highest-scored cards using ones from their own hand.

While you’re waiting for your games to arrive, learn about 100 women who changed the world.
