> In fact, in public discourse often the opposite is true.
This isn't just true in public discourse by the way. It's true in proposal/grant writing, legal argumentation, or even just arguing with your parents. You should always lead with your strongest arguments, and think very carefully before including any weak ones. Humans are just bad at doing weighted analysis of persuasive arguments. Say you have an argument, with three points, with weights: 0.9, 0.05, and 0.05. Your opponent destroying your two weak arguments is going to convince the reader or decision maker far more than the 0.1 combined weight of the arguments.
My exposure to the subject has been in the legal context. This is a popular textbook on legal argumentation: Gardner, Legal Argument: The Structure and Language of Effective Advocacy. Someone has an older edition for cheap on EBay: http://www.ebay.com/itm/LEGAL-ARGUMENT-THE-STRUCTURE-AN-/310.... The text is quite general, not all that specific to the legal context.
