What kinds of actionable plans ever result from blaming people (as a category)? Where will it get you? Expecting some people to behave differently... just "because"? What kinds of plans flow downstream from blaming human nature? What's the plan? Does it help you somehow, practically? Or is it mostly about feeling better somehow?

If the plan is persuasion, putting blame aside goes a long way.

If you want to make change based in the real world, you could do worse that reading and absorbing "Thinking in Systems: A Primer" by Donella Meadows.
