I do the same, but I slightly modify this. Sometimes I respond fast, but a lot of times I like to say “I have an idea that is not thought out but what if…” and go on. That gives me time to process it and I can bounce a terrible idea out of others and I can say “ok yeah like I said I didn’t think it through but it was a bad idea” or it can be refined and clarified. I use the group to think it through with me. It helps.
