Optical illusion reveals if you're gullible or sharp-minded and can see through lies

At first glance the picture appears to be a penguin stood up facing left against a blue background but a second glance reveals another dimension to the image and which you see first reveals something

What you notice first about this brainteaser could reveal whether you are a gullible person or someone who is hard to trick.

At first glance the picture puzzle appears to be a penguin stood up facing left against a blue background. But a second glance reveals another dimension to the image. Focus on the black dot on the penguin’s belly and the image quickly resolves itself into a picture of a man’s head. The black dot is the man’s eye, while the bird’s black head becomes an Elvis-style quiff. The dip in the penguin’s belly also serves as the man’s nose.

Depending on which image you see first, bird or man, it can reveal information about your character, according to the puzzle’s creators. These illusions take place due to how our brains interpret visual data in various ways, putting our perception to the test. And according to ZenBuisness: "These visual puzzles can give you a good mental workout that can, in turn, help you think more efficiently and solve problems more easily."

As well as being a fun way to pass the time these puzzles can also be a boost to your grey matter. Completing challenging puzzles, brain teasers and optical illusions can help improve your cognitive function, boost productiveness and memory. You are super quick with a sharp intuition and strong levels of emotional intelligence if you spotted the penguin first, say the creators.

Meanwhile if you spotted the man who looks like Elvis first it means you you may be less gullible and easier to please. People in this second group may also be more innovate and better problem solvers, although they rely less on their gut instinct. If you found that one too easy you can try your hand at what has been called the "trickiest" optical illusion puzzle on the internet. In this classic brainteaser viewers are tasked to find the sailor’s wife in the picture of a man looking out to sea. While it sounds simple enough this puzzle had Tiktok users flummoxed with thousands of people left bemused trying to spot her.
