Prediction Markets for the Reproducibility of Psychological Science The prediction markets for the reproducibility project will soon be up and running -‐ please participate! There will be around 30 prediction markets, each representing a particular study that is currently being replicated. Each market can be summarized by a key hypothesis that is being tested, which you will get to bet on. In each market that you participate, you will bet on a binary outcome: whether the effect in the replication study is in the same direction as the original study, and is statistically significant with a p-‐value smaller than 0.05. Everybody is eligible to participate in the prediction markets: it is open to all members of the Open Science Collaboration discussion group – you do not need to be part of a replication for the Reproducibility Project. However, you cannot bet on your own replications. Each study/market will have a prospectus with all available information so that you can make informed decisions. The prediction markets are subsidized. All participants will get about $50 on their prediction account to trade with. How much money you make depends on how you bet on different hypotheses (on average participants will earn about $50 on a Mastercard gift card that can be used anywhere Mastercard is used). The prediction markets will open in about 2 weeks and will be open for 2 weeks. If you are willing to participate in the prediction markets, please send an email to
[email protected] by November 1 and we will set up an account for you. Before we open up the prediction markets, we will send you a short survey. The prediction markets are run in collaboration with Consensus Point. If more than 100 individuals would like to participate we will randomly draw a sample of 100 individuals out of those that want to participate. If you have any questions, please do not hesitate to email
