I would de-emphasise pop psychology, and more emphasise:

- clarity: while not everything has a right or wrong answer, but lots of things do

- robustness: it's okay for people to disagree with you, and also for you to be wrong and learn from it

- reason: avoiding the standard fallacies

- agreeing to disagree: individuals you know/interact with and your relationships with them are more important than abstract tribes you may or may not belong to
