Not every change is an improvement, but every improvement is a change. “True Scotsman Fallacy” is about changing the question under discussion in an unhelpful manner, often in order to avoid the evaluation of the original question. If we agree that different questions have different degrees of usefulness (given some state of understanding), different ability to elicit further understanding, and are motivated by various purposes (as opposed to somehow being important in themselves), then serving the purpose of a question naturally employs developing different, more useful questions, and shifting the focus of investigation to them.
