If you put 57 random people in a room it turns out, you can predict with 99% certainty that 2 of them will have the same exact birthday.
To most, this seems counterintuitive...and wrong.
But mathematically, it's absolutely right. This is why statistics is so important. It turns out human beings make cognitive errors all the time when looking at the world, especially when trying to see patterns, are trying to determine causality. In a world where we're required to make important decisions based on massive amounts of data, we can't just "eyeball" it.
You don't have to be a master in statistics, but you at least have to understand that it exists. And then you need to find someone (or a machine) who does understand it to help...or suffer the painful (but often silent) consequences.
