How do we respond when our ideas are challenged?
We might pose this question:
How do you respond when ideas you have some investment in are challenged by a different viewpoint?
Typically people push back when their ideas are challenged.
Rather than reflexively defending your views, another possibility is to pause and consider what merit, if any, there might be in the challenge.
A challenge could be spot on. At the other extreme, it could be mere fantasy on the part of the challenger. In between, it could have some elements worth considering.
