These are great! Now I have to get the book. These are all very true (and, speaking from an unfortunate wealth of meeting experience, too familiar), but one curious thing is that #2, 3, 5, 6, and 8 — at least — will bring some actual value into the meeting even if the user’s purpose was only to appear smarter. Re-stating 25% as one in four, for example, does bring a different perspective because it’s more humanizing. It feels more like we’re talking about real people where “25% of users” is a blurry, abstract statistic, and the distinction may help steer the discussion in a new direction.
And sometimes, breaking into an hour-long drone with almost anything can re-energize a meeting and get people engaged again. So all ten of these get credit for spicing up a meeting.
