A seemingly unfortunate list of techniques.
- “what makes you think”/“why do you believe” often comes off sounding very arrogant
- “so you’re suggesting that…” is very close to the nasty “so you are saying that …” which again always comes off as very arrogant.
- “Use scientific visuals” Really? This backfires far too easily. Either people respond emotionally because they don’t understand what they are seeing, or as @wsmcneil pointed out, they know their facts and the discussion gets derailed
- “Demonstrate that other people agree” AKA appeal to popularity. 9 out of 10 dentists recommend Splorch Toothpaste for a glowing smiles!
- “end your sentences with verbal affirmations” Far too many ways to abuse this one
Every single one of the “how to get agreement” examples come off as very snide.
If this is how to “win” I’d rather not play.
