A first counterintuitive aspect: the choice after the event (post factum)

They are several strategies according to our environment:

• Planning: in a predictable situation of rare ressources, there is a need to optimize and not spoil them;
• Negotiation: when ressources are rare and events unpredictable, negotiation allows to make a choice in the present for lack of being able to make it in advance. This is the case for example of pricing in the market economy;
• The choice after the event (post factum) : when you enjoy an abundance of resources (a large group, loads of information), but when the situation is not predictable, then you'd better create an abundance of choices and choose post factum among all opportunities. This approach is the basis for cooperation as we will discover.

Often we do not choose our strategy but use the one we master, whatever the context. It is important to adapt to the environment and to select the best strategy. Sometimes the situation can be predictable for some events and unpredictable for others, some resources may be abundant and others rare. In this case, we need to adapt and even juggle with strategies. The one concerning cooperation is rather counterintuitive , because it compels us not to choose as early as possible while we bathe in a culture of anticipation, and they push us to work with plenty when we are used to focus on what is rare.
