10 Mind-Blowing Psychological Phenomena You’ve Never Heard of

Mind-boggling paradoxes, phenomena, and effects intrigue us even if there’s a logical explanation for them. When you face them, you might feel that someone is interfering with the laws of nature.

Bright Side found several brain-twisting paradoxes and problems that you can test yourself and decide whether to believe or not.

10. Birthday problem

This paradox suggests that in a group of 23 people there’s a 50% chance that at least 2 of them share the same birthday. In a group of 60 people, the probability reaches almost 99%.

Do you think it’s absurd? That’s the whole paradox. However, the mathematical calculations prove that it is actually possible.

9. The Baader-Meinhof phenomenon (frequency illusion)
