-
- Agree.
-
- In rubber-banding, control works best when the controlee doesn't pay
- attention to the actions you want to see.
-
- Yes.
-
- >Manipulation can be aided by the manipulee having a high gain for,
- and >paying close attention to, the actions you want to see.
-
- Disagree. Control is never done by paying attention to actions, unless
- it's specifically the perception of the action that you're controlling
- (as in dancing). And then, of course, the means of creating that
- perceived action are varied automatically (muscle tensions).
-
- Here's what I think you are talking about:
-
- Ref Sig
- |
- p = f(v1,v2) ---->(C)--->
- | |
- | |
- (I) (O)
- MARK / | |
- / | Mark's action
- / | |
- v2 v1 <---------
- manipulator's report| |
- ---- manipulator<---
- |
- ref lev for other's action
-
- v1 is a controlled perception, and v2 an uncontrolled one (but not a
- don't-care perception). v1 is called controlled because the Mark's
- action really consists of setting a reference level for v1 which lower
- systems successfully meet.
-
- This diagram shows what happens when the Mark is controlling a
- perception that depends on several lower-order or external variables,
- only one of which (v1) is reliably affected by the action. If the
- manipulator can get the Mark to accept the manipulator's description
- of v2, instead of the Mark perceiving v2 directly, the manipulator can
- misrepresent the state of the environment and thus gain control of the
- Mark's action.
-
- Hey, Olson, don't take this personally.
-
- In the con game this happens when the wallet (v1) containing the valid
- bond or Treasury note or whatever (v2) is switched for the similarly-
- wrapped one containing newspaper. The Mark has control only of the
- wallet (v1), but is shown by the con man that the wallet contains
- something valuable (v2). The Mark doesn't want to perceive the wallet
- alone (v1) but the wallet with something valuable in it, which is the
- perception p = f(v1,v2).
-
- The action that gets the wallet and v2 into possession of the Mark is
- to hand over cash to the con man. This does get the wallet into the
- possession of the Mark. The Mark perceives this, however, as getting a
- wallet with something valuable in it. The con man sees to it that the
- Mark gets the wallet, but without the something valuable in it.
-
- This is the same con game played by advertisers; when you hand over
- your money, you get the flashy car, but the nice pretty girl isn't in
- it any more and never will be. What you get is a dumb promiscuous
- broad who can be conned into thinking that a flashy car contains a
- terrific guy, and when she hands over the price she will give you a
- baby you didn't particularly want, or AIDS. And when she looks in her
- package all she will find in it is plain old you. Great design for a
- relationship.
-
- I agree with you that lots of this kind of deception goes on. What's
- good about it?
-
- The only way for the Mark to stop being conned is to make sure it's
- his own perception of v2 that's in the package. This goes whether he
- is buying wallets from strangers, cars from television advertisers,
- religions from books, or educations from experts. Or theories from
- anybody.
