An Active discussion is more than emphatic words

For many years in my early career, I believed that words make the most emphatic point, especially in a business, project or even negotiation discussions. I would strongly guard my point of view, while trying to come across as open to others perspective. The more emphatically I wanted to make the point, the more saw my self repeat it during the discussions. Mid way through listening to someone's perspective I would start nodding in agreement or getting ready to launch a counter view.

Over time, I have had a few learnings to enable a more meaningful discussion. I believe repeating something doesn't make it more powerful. Three things that can help elevate the discussion, in addition to making your point.

1. Listening with curosity rather than with an attempt to respond; when we are keen to respond, we end up missing the other's point or putting them off in the process.
2. Asking open ended questions rather than closed ended questions, for they facilitate and broaden the discussion vs. constraining it.
3. Using silence and pauses after making a point or before responding, as means to have people reflect on things. The less dense the conversation, the more productive it may well be.

Anything you would add to the list for having a productive conversation.
