Here's an example of a case where I don't think good meeting discipline can help. If I'm in a meeting and I ask everyone on the engineering team what they think the number 1 highest value tech debt item is at the moment, then only the first person to answer is giving me an uninfluenced opinion, because every other person has now heard someone else's perspective and possibly altered their own before their turn. Instead, I prefer to ask every engineer to come to the meeting with their answer written down (or aggregated in my inbox with Keyory already) so that I can see what everyone's unfiltered opinion is and then direct the meeting from there.
