This too is not the key point in question. Your reaction here can be expected to correlate with other reactions you would make in situations not necessarily related to PR. In particular it says something about potential responses to ego damaging information. I am sure you can see how that would be relevant to estimates of possible value (positive or negative) that you will contribute. I again disclaim that 'influences' does not mean 'drastically influences'.

Note that the reply in the parent does relate to other contexts somewhat more than this one.
