You’d think we would know better.
The old adage, “the worst beginning to a sentence is, ‘Why can’t you just…’” is something we understand viscerally. Seemingly doesn’t stop us from doing it to others.
A former boss had a little sign on his desk that said "All you gotta do is..." as a reminder that seemingly simple solutions are often devoid of the necessary nuance and understanding of the problem.
I now actively try to avoid using that turn of phrase, and when I catch myself about to say/saying it, I check myself and remind myself that I'm also susceptible to this blind spot.
