Czech forecasting tournament OPTIONS


About project OPTIONS

České priority, z.ú.

Project OPTIONS is a series of forecasting tournaments in the Czech Republic with the aim of finding the best forecasters in the country to create an expert forecasting team. This team will be at the government’s disposal to aid its efforts to make well-informed decisions especially during situations of crisis and high uncertainty.

Our tournaments are running from March to May 2021. In these, our forecasters will give their predictions for no fewer than 24 questions within four rounds. These questions will concern a myriad of subjects, ranging from the impact of Covid-19, unemployment figures, mental health issues to concerns about cyber attacks.

We are proud to be partnered with Cultivate Labs who have built the online platform where the tournaments are held and have provided us guidance on how to set up and run the tournament, and on forecast question best practices.

Related project run on Cutlivate Labs' platform is Cosmic Bazaar featured in The Economist.

We are working in tandem with several Czech governmental institutions to provide the questions that will be posed to our forecasters. Among our partners are the National Cyber and Information Security Agency, the National Institute of Mental Health, the National Monitoring Centre for Drugs and Addiction of the Office of the Government.

Project OPTIONS is an endeavour organised by Czech Priorities, an NGO based in the Czech Republic that aims at promoting evidence-based policy making in the country. The project has received grant support from the Technology Agency of the Czech Republic.

If you have any questions or would like to get in touch with our team, please contact us at options@ceskepriority.cz.

Are you studying at UK? We are teaching a new elective course "Innovations in Policy-Making (JTM381)" at FSV from October. It will include an autumn forecasting tournament, so you can motivate each other and get some credits for it. In addition, we will discuss public decision-making and methods to improve it. The course is partly experimental and draws heavily on resources from the international community of rationalists and effective altruists. The class will be taught in AJ and the course is primarily aimed at M.A. students, but you can also apply if you are studying for a BA or are studying at another institute or faculty. We are looking forward to it!
