I am reading: Think Again by Adam Grant. In the first chapter, he mentions the three different mindsets as told by his friend: preacher, prosecutor, and politicians.

We get into preachers mode when our sacred beliefs are in jeopardy: we deliver sermons to protect and promote our ideals. We enter prosecutor mode when we recognize flaws in other person’s reasoning: we marshal arguments to prove them wrong and win our cases. We shift into politician mode when we are seeking to win over an audience: we campaign and lobby for the approval of our constituents.

If you are on Twitter, you can witness thought leaders, propagandists, sellers: all in your timeline. Why don’t you start categorizing them and their sermons? 🙂
