Query: by what objective criteria do we determine whether a political decision is rational?
I propose that the key elements -- necessary but not sufficient -- are (where "you" refers collectively to everyone involved in the decisionmaking process):
you must use only documented reasoning processes:
use the best known process(es) for a given class of problem
state clearly which particular process(es) you use
document any new processes you use
you must make every reasonable effort to verify that:
your inputs are reasonably accurate, and
there are no other reasoning processes which might be better suited to this class of problem, and
there are no significant flaws in in your application of the reasoning processes you are using, and
there are no significant inputs you are ignoring
If an argument satisfies all of these requirements, it is at least provisionally rational. If it fails any one of them, then it's not rational and needs to be corrected or discarded.
This is not a circular definition (defining "rationality" by referring to "reasonable" things, where "reasonable" depends on people being "rational"); it is more like a recursive algorithm, where large ambiguous problems are split up into smaller and smaller sub-problems until we get to a size where the ambiguity is negligible.
This is not one great moral principle; it is more like a self-modifying working process (subject to rational criticism and therefore improvable over time -- optimization by successive approximation). It is an attempt to apply the processes of science (or at least the same reasoning which arrived at those processes) to political discourse.
So... can we agree on this?
This is a hugely, vastly, mindbogglingly trimmed-down version of what I originally posted. All comments prior to 2010-08-26 20:52 (EDT) refer to that version, which I have reposted here for comparison purposes and for the morbidly curious. (It got voted down to negative 6. Twice.)
For what it's worth, here are the references. I'll add a link here from the main post.
"Spot the Loonie!" was a Monty Python satire of a game show. I'm using it here to refer to the idea of being able to tell when someone's argument doesn't make sense.
"How to Identify the Essential Elements of Rationality from Quite a Long Way Away" refers to the title of a Monty Python episode whose title was, I think, "How to Identify Different Types of Trees from Quite a Long Way Away".
"Seven and a Half Million Years Later" refers to the length of time it took the computer Deep Thought, The Second-Greatest Computer in All Time and Space, to calculate The Answer to The Ultimate Question of Life, The Universe, And Everything (in The Hitch-Hiker's Guide to the Galaxy, aka H2G2).
"I really have no idea if you're going to like it" refers to Deep Thought's reluctance, seven and a half million years later, to divulge The Answer: "You're really not going to like it." "is... is..." refers to this same dialogue, where Deep Thought holds off actually giving The Answer as long as possible.
"The Question to the Ultimate Answer" refers to the fact that, having divulged The Answer, it pretty quickly became clear that it was necessary to know what the Ultimate Question of Life, The Universe, And Everything actually was, in order for the answer to make any sense.
"So, have we worked out any kind of coherent picture... Well no..." refers to a scene in H2G2 where usage of The Infinite Improbability Drive gives rise (quite improbably) to the existence of "a bowl of petunias and a rather surprised-looking sperm whale", the latter of which immediately begins trying to make cognitive sense of his surroundings. After assigning names (amazingly, they are the correct English words) to several collections of perceptions in his immediate environment, he pauses to ask "So, have we built up any coherent picture of things? Well... no, not really"... or something like that.
"A Theory About the Brontosaurus" refers to a Monty Python sketch in which a talk show interviewee has a theory (about the brontosaurus) which she introduces many times ("This is my theory. (cough cough) It goes like this. (cough) Here is the theory that I have (cough cough cough) My Theory About the Brontosaurus, and what it is too. Here it goes.") before finally revealing her utterly trivial and non-enlightening conclusion.
"ahem ahem" refers to the interviewee's repeated coughing-delays in the above sketch.
