When a learner asks a question, I often hear their peers and teachers respond in a way that suggests “don’t ask that question; learn something different”. I see the same thing occurring on Q&A support boards all the time:
Questioner: “I was wondering how to cook an egg in the microwave.”
Supposed answerer: “Don’t use a microwave, use a pressure cooker.”
Supposed answerer: “Why would you want eggs? Go vegan.”
As an educator myself, I find it’s better not to say NO to someone interested in learning and instead say, “yes… and…….” to find out what interests them and connect the topic to their interests.
It’s a lesson I draw from the improv and acting communities: “no, but…” (or even “yes, but…”) stops conversations. “yes, and…” encourages them.
