When we have to make a decision, we consider all the pros and cons, try to gather a lot of information and estimate what consequences this decision might have. And then we make an (at least somewhat) rational decision. Or do we?
Petter Johansson, a cognitive scientist at Lund University, presents results from experiments he conducted and suggests: More often than not, it is only after we have made our choices, that we come up with reasons for it.
Comment from our editors:
Very relevant evidence for the absence of rationality in decision making.
