Can you guess how many eggs are left?

Let's be honest: we all love those little riddles that circulate among friends, the ones that seem childish but manage to make us hesitate, smile… or doubt our logic. And sometimes, behind a seemingly simple puzzle, lies a real lesson about how we reason. So, when a reader asked me, “I have six eggs, I crack two, I fry two, I eat two… how many do I have left?”, I immediately wanted to take you along on this delightful little investigation. Because yes, this kind of riddle says a lot about our practical minds and our way of seeing things!

Why do these riddles always trap us?

It quickly becomes apparent: this type of puzzle doesn't rely on mathematical skill, but on our intuition… sometimes too quickly. Our brain loves to get straight to the point, especially when the problem is short. We mentally add up the actions—break, cook, eat—and presto, the answer seems obvious.  Spoiler alert  : it never really is.

This phenomenon even has a name: it's called mental impulsivity bias (a very simplified version, don't worry!). In short, we rush to the calculation instead of paying attention to the meaning of the words. And that's exactly why these famous riddles are so popular: they tickle our little "I'm so sure of myself... oh really, not so sure?" side.
