Back in December I shared that we really don’t understand exponential growth. Well I’m about to share a question with an answer that will boggle your mind. All I ask is that you make a guess at the answer before looking at it.

Imagine we get every single human being on earth to play a ‘winner play on’ game of rock-paper-scissor. First, let’s round up the population to 8 billion. And let’s assume every one of them can play.

A game of Rock-Paper-Scissors with 8,000,000,000 people.

So the first round will be 4 billion pairs of people, with 4 billion losing, and 4 billion winning and moving on to the next round. The question is:

How many rounds of rock-paper-scissors will the winning person have to win consecutively in order to be the world champion?

Guess.

I’ll give you a hint: it’s less than 100.

What do you think?

Here is the answer.

Well, what if we added another 1/2 billion people? That would be 500 million more players, or 8.5 billion total. The answer would still be the same!

Hard to believe. It’s so difficult to wrap your mind around needing this many games to whittle 8 billion people down to one winner. It just doesn’t seem right… but it is.
