They're only the same thing if you ignore intent.

Not everyone lies or is cynical when convenient. Skill, rate of success, and personal ethics are all orthogonal concepts.

Above all, intent matters. I do not treat someone who I perceive to be manipulative the same as I would other people.

> all orthogonal concepts

That's my point exactly. I just also assume the % of liars in 30s is the same as in general population by default.
