The European Summer Program on Rationality (ESPR)

About the Program

The European Summer Program on Rationality (ESPR) is an immersive 10-day workshop for mathematically talented students aged 16-19 with a desire to understand themselves and the world. Organized by FABRIC, a Prague-based nonprofit funded by Carina Initiatives, ESPR is held at a residential venue in Somerset, United Kingdom. The curriculum covers topics from game theory, cryptography, and mathematical logic, to AI evaluation, argumentation, communication styles, and cognitive science. The goal is to help students develop rigorous, quantitative skills and a toolbox of useful concepts and techniques applicable in all walks of life. A sister program, PAIR (Program on AI and Reasoning), is available for students aged 16-21 who are interested in AI-focused content.

The application page confirms the extended January 12 deadline at the end of the day Anywhere on Earth. These are historical 2026 dates. No 2027 application deadline or program dates were found on those pages.

Eligibility

Mathematically talented students with a desire to understand themselves and the world. Curious about decision-making and modeling the world. Passionate about cognitive science, mathematics, philosophy, economics, logic or history. Applicants must be between 16-19 years old. Individuals younger than 16 cannot be accepted due to venue restrictions. Those aged 20 may consider applying for the PAIR program.

How to Apply

The application process involves three stages: Stage 1 requires submitting an application form, which includes a task and open-ended questions. The application form is shared with the PAIR (Program on AI and Reasoning) camp, allowing applicants to apply to either or both programs. Stage 2 consists of approximately two hours of tasks, with invitations sent within two weeks of the deadline. Successful applicants are then invited for an online interview in Stage 3, with final decisions expected by mid-April. Applicants are allowed to use large language models but must disclose which model was used and how.
