What are some of the most mind-blowing facts? by Hien Lam

Answer by Hien Lam:

I think it’s mind-blowing that these two lines are the same length.

Go ahead and measure for yourself but they are the same length.

Why does the vertical line look so much longer?

This mind trick is known as the Vertical-Horizontal Illusion.

It is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length.

This illusion actually plays an important role in your drinking habits.

When you pour a drink, you usually base your decision on when to stop pouring based on the height of the liquid in the glass. You stop pouring a drink when you think the glass is full.

The problem is, you end up ignoring the width of the glass completely.

Short, wide glasses give the illusion of containing less liquid. Because of this, you end up pouring more liquid – on average, 30% more than you would with a tall, skinny glass.

So use tall skinny glasses instead of short wide ones, and you can change your drinking behavior without really changing anything at all.

It’s known as the Delboeuf Illusion.

Delboeuf was a 19th-century Belgian philosopher, and he discovered if you surround two identical circles with different amounts of “white space,” people think they’re looking at two different circles.

The more “white space” around the circle, the smaller the circle appears.

How can you use the Delboeuf Illusion to eat less?

If you put food on a small plate, your mind will tell you that you are eating a large portion and you’ll stop adding. That visual cue will trick your brain into thinking it’s had enough to eat.

However, when you use a large plate, you have to add a lot of food on it to make it look full. If your brain thinks you’re eating less, the more likely it’ll be to want a second serving.

Using the illusion, you can see that the plate on the left looks fuller than the one on the right.

And it’s why the bowl of cereal on the left below looks less full than the one on the right. And that’s why the small plate feels fuller and more filling.

A study shows that eating from a 10-inch plate instead of a 12–inch one cuts your calories by 22%! That means this small change could result in an estimated 10 pounds in weight loss over the course of one year!

It is easier to change your food environment than to change your mind.
