As traditional instruments reach their limits, it is no wonder that the question arises of whether behaviourally-inspired strategies might be (at least theoretically) an elegant tool for public actors to make people do what governments want. Keeping this in mind, this chapter will question how behaviourally-inspired policies can be understood generally as a tool of government that is used to make people do what governments want. It will argue that the available government tool typologies do not cover the ways in which behavioural insights change traditional instruments in specific ways. This ‘enzymatic effect’ of behaviourally-inspired policies will be explained as a specific concept. It will be adapted in order to devise a new model of governmental instruments.
