Something for Everyone's Desk
Anderson Layman's Blog has Rotary's 4-Way Test for ethical decision making.
I teach workshops on that topic and am a major fan of the Josephson Institute of Ethics decision making framework. Various ethical decision making models have their benefits, but a big advantage of the Rotary 4-Way Test is its simplicity.
A person does not need to recall helpful rules from Kant, Mill or Bentham to able to get "in the ballpark" for most issues with the Rotary Test.
