So it’s important to consider the big ideas because they become internalised and act as ‘meta-norms’ that govern our thinking without our really being reflectively aware of this fact.
On the other hand, the point of introducing into the debate new knowledge in decision-making theory is twofold: it can be used to put to bed the defunct paradigm in the face of stalwarts who won’t give it up; and it can be used to help construct a successor paradigm that is better at predicting behaviour and facilitating the kind of socio-economic world we want.
And of course it is important to bring in practical application. For there is little point in connecting the big ideas with new knowledge in order to construct a new paradigm if this does not gain traction on social reality. Moreover, there should be bottom-up feedback that informs and fine-tunes the policies that the paradigm yields, lest groupthink set in again.
