A rooster is on a roof of a barn

facing east

The wind is blowing

to the west at 10 mph

The rooster lays an egg.

Which direction does the egg roll?

If you want, you can pause the video and think it over.

The answer?

There is no egg.

The rooster didn't lay one because roosters are male.

Did you get it right?

Let's pick this apart and see why people have difficulty with this brainteaser

and so many others.

First, it's easy to overlook details

or accept them without questioning.

In this brainteaser, the answer could be found in the second word.

Rooster. In hindsight, we realize

it's impossible for roosters to lay eggs

but it's easy to overlook when

it's mentioned casually in the brainteaser.

Another process at work in this brainteaser is misdirection.

There were several details included

that we may have paid too much attention to.

The fact that the rooster was facing east

and that the wind was blowing west at 10 mph.

In the end, these details had nothing to do with

the actual answer.

But because they seemed important in the context of the brainteaser,

they directed us away from the relevant information.

The same techniques used to solve brainteasers

can also be applied to real-world situations.

When you're trying to figure something out,

it's important to analyze the information that's available to you.

Are there any key details I may be missing?

Am I being misled by something?

Could I be thinking about this in another way?

Brainteasers not only help to keep your mind sharp,

but they can help to improve your critical thinking skills as well.

Let's finish things off with another brainteaser.

You have a single match and are in a dark room

with a candle, an oil lamp, and a gas stove.

Which do you light first?

The answer? The match.
