Optical illusion personality tests often trick the brain and the eyes into believing what we see first among the many images layered into the photo, based on our perspective, and it is not surprising to notice that our friends standing right beside us spot just the opposite of what we see.

This optical illusion here is a simple black-and-white sketch that seems to show two things at once depending on how your brain chooses to read it, and claims that whichever animal you spot first within 5 seconds reveals something about your personality.

Are you spontaneous and easygoing, or thoughtful and prefer to stick to the plan?

It first appeared anonymously in the German humour magazine Fliegende Blätter in October 1892, captioned “Which animals are most like each other?”

But before you try looking for the answers, take the test yourself first.

Here is the image.

Give it 5 seconds.

So, what did you spot first?Photo: Fliegende Blätter
