Definitions at the centre of behavioural science

📐 The behavioural sciences use a scientific approach that relies on experimentation.

The idea is to understand human functioning, the actions of individuals in general (from a theoretical point of view) in order to be able to identify levers for action (from a more applied point of view).

📐 Thanks to numerous studies on human cognitive functioning, we now know that our rationality is limited (thanks D. Kahneman and A. Tversky!).

Indeed, our decisions are influenced by our cognitive biases and the behavioural sciences take these into account to understand our behaviour.

📐 When we act, we choose to perform one behaviour rather than another. Thus, taking action is always a matter of decision.

What determines this decision? What parameters influence our choice? This is what the behavioural sciences are interested in.

📐 A practical application of the behavioural sciences, the Nudge method reduces what is known as the "intention-action gap" .

It must obey the 3 golden rules defined by R. Thaler (Nobel Prize in Economics 2017): voluntary, transparent, and win-win.
