- Thankyou for your useful comments. Here are my best attempts at answers.
-
- Last first - I had an assumed context, if you like, the relation between
- a decision maker setting policy, and their staff. Problem - how to best
- support the decision maker. The staff want to get the best information
- to the decision maker as soon as possible. If the staff are good
- collectors, then this comes down to making sure staff and decision maker
- are singing from the same sheet of music (same Aristotelian Propositions)
- and optimising channel bandwidth - there are some things rather like
- maximum power transfer and impedance matching, but a bit beyond what
- seems to be in the literature. In these circumstances staff will need
- to control for best understanding by decision maker, and to flag any new
- Aristotelian Propositions not yet in the decision maker's reference set,
- and develop Hamming distance like associations with things already known
- to decision maker. Essentially the game of 20 questions (20 bits
- can distinguish between elements of a quite large ensemble).
-
- It's slipped my mind what the other two questions were, and being logged
- in on a dumb terminal I can't open a window to reread yr. mail. Can I
- finish my reply when I come back from out of town. Early next week I
- hope.
-
- I didn't intend to suggest that people ALWAYS control for mutual
- understanding. At times deception is wanted - see for example WWII
- where it was worth many British and American lives to deceive about
- the place of landings on D-day.
-
- But if speech is going on in order to communicate, then I think people
- DO control for understanding, and that was the assumed context of my
- reply to Penni. And Penni's statements from the K-B seem to me first
- cousins of Aristotelian propositions. And the distance between beliefs
- and experience does seem to me to be a Hamming distance, probably with
- weights - if you have just arrived in a strange town, you are probably
- more concerned about finding your hotel than the dairy.
-
- Sorry - there's the 'phone. Have to go. Will continue later.
