Wijsneus Festival


Come and have a look around! On this festival we will show you how we as people make choices and why we feel, think and do certain things.



On Friday afternoon, September 16, 2022, the Knowledge Center for Psychology and Economic Behaviour and Leiden University are organizing the small-scale Wijsneus Festival in Park de Leidse Hout.

For example, we will answer the following questions by means of experiments and short talks: Can we properly assess whether a suspect on camera is guilty or innocent? How useful is it to punish people when they go the wrong way? Have you ever seen your heartbeat on a heart film? And how do we deal with our waste in nature?


  • Test yourself in various experiments. You can even make your own heart movie! (Experiments are in both English and Dutch).
  • Listen to short talks by behavioral scientists Welmer Molenmaker, Henk Staats and Anouk van der Weiden of Leiden University. (Talks are all Dutch).
  • Be surprised by Rich Magic the illusionist.
  • Enjoy live music from the band Moon About and guitarists Jens, Mees and Stefan
  • Tasty snacks and drinks from the Theehuis.  

It will be an exciting afternoon. Full of surprising insights for both young and old, nice music, snacks and drinks.
