Have you ever tossed a coin to settle a bet and wondered which side to choose?

Diaconis proposed model predicting ~1% bias in favor of the starting side up. However, no one has collected a large enough data set to test this hypothesis YET.

Watch us do it https://www.twitch.tv/cointossingteam

We are a bunch of researchers coin tossing from 9am to 9pm CET today. Yes, this is a ridiculous project but what is life about when you don't do something stupid from time to time?

We collected almost 60,000 coin tosses in a single day! Next year we will organize a few more data collection events in Amsterdam.

We are still open to people interested in contributing to the study (osf.io/hkv8p/)!
