What it is
Rock Paper Scissors is a way to resolve a conflict or by two people making the shape of a rock, paper or scissors to decide who wins. Rock smashes scissors. Paper smothers rock. Scissors cut paper
Why it matters
Likely you were introduced to it as a kid like I was, and then grew out of it. Eventually you opted to rely on more 'adult' ways to make decisions. Perhaps tough as you read this now you might re-consider introducing one of our oldest traditions back into your tool box to resolve conflict. Imagine how lovely it would be to have an answer to whose turn it is to do the dishes tonight in seconds? Why rehash the past? And, it is my belief, Karma plays an important part here, and it all evens out in the end.
The origins of Rock Paper Scissors has been traced back to the Han Dynasty in China to around 200 BC. It then spread through Japan, Korea, Indonesia finally making its way to Europe and then North America. There does not appear to be a tradition in Africa or South America of resolving conflict this way.
