“Why would they do that?” asked with curiosity makes you smarter. Asked with judgment, it makes you smaller.

The same words can be an opening or a verdict, depending on whether you actually want the answer. Asked with curiosity, the question assumes there is a reason you have not seen yet, and you usually find one. Asked as judgment, it closes the matter before any information arrives, and you leave with nothing but a lower opinion.

Catch yourself mid-question and check which one you are doing. If the honest answer is judgment, try finishing the sentence with what you would have to believe for their choice to make sense.
