What will it be like to study at Leiden University in 2075? Ten surprising, artistic uni-visions could be brought to life. It’s up to you to vote for your favourite.

Jurist Gineke Wiggers wants to predict the expected impact of legal articles. Carel Stolker, Rector of the University and, like Wiggers, a legal specialist, is enthusiastic about the research. ‘A big data project like this will help us establish the effect of our work on society.’

A series of workshops at Leiden University and the University of Hamburg will act as a forum in which international legal scholars whose research adopts a behavioural approach can present their works-in-progress and gain feedback from a broad range of peers, including scholars in economics and cognitive…
