“I don’t know what you think about this point, but I think <lots of opinion here>…” to me isn’t an effective way to request contribution from others. To me, it can be considered a violent act, especially if others are one’s subordinates.
“What do you think about this point?” at least opens up space for a contribution.
“Would you be willing to share your views on this point?” might be even more effective.
Four and a half years later, I’m a little surprised I reacted so strongly to this. Looking back, I can only assume that this situation involved significant asymmetry of power and that I perceived it the way I described it. This seems to re-inforce the point I was trying to make.
