Can Superstitions Benefit Your Mental Health?

You Should Know: Maybe you’ve learned over the years that going outside with wet hair doesn’t actually give you a cold (viruses do that), but you might still blow-dry before leaving the house, just in case. That tension between science and superstition is completely normal. Our brains don’t replace outdated beliefs with new ones — we file them alongside each other. Basically, science stays in one corner, grandma’s wisdom in another — and when we need to explain something quickly, we grab whatever pieces are nearby.

Going Deeper: The good news is that holding onto superstitions isn’t necessarily a sign of irrationality. Research suggests that good luck rituals (think crossing your fingers or carrying a lucky charm) can actually boost performance by soothing anxiety. But a superstition becomes problematic when it takes over. So don’t let it prevent you from doing things, like panicking when there’s no wood nearby to knock on.  

Takeaway: Superstitions stick around because they serve a real psychological function, even when we know better intellectually.

Bottom Line: Go ahead and knock on wood. Just don’t let it take control.
