> Economic models, however, are themselves part of the economy. The ideas they are built on and their predictions become part of wider knowledge and influence the very thing the model is trying to predict or explain, possibly reinforcing or weakening certain behaviours.

> The only time avoiding the certificate entirely is when the signal it provides is negative.

It is possible for the same action send a positive signal when done by some people and a negative signal when done by others. Specifically there can be 'contersignaling' [0], which is basically signaling that you don't need to signal.
