LCIL Friday Lecture: 'The Behavioural Turn of the United Nations and its Implications for International Law' - Prof Anne van Aaken, University of Hamburg

45 minutes

Lecture summary: United Nations (UN) and several UN Agencies have started to use behavioural sciences in order to achieve their policy goals, including for achieving the Sustainable Development Goals (SDG). While it is to be appreciated that insights on actual behavior inform policy making of international actors, they raise scientific and normative considerations warranting caution. First, for those considerations it matters, who the acting and the targeted actors are, that is, where and for what behavioral sciences are used (inter-state or targeting citizens). Behavioural interventions come in many facets and warrant a differentiated view – a finely built roadmap is thus desirable. Second, there are concerns about the internal and external validity of experimental research on which behavioural sciences largely, but not solely, draws. Third, taking a differentiated view on behavioral sciences also allows for a more finely grained view on normative concerns underlying the operations of the United Nations. This contribution spells out those considerations while still advocating for the approach as such.
