Good post by Robin Hanson, well-worth reading.
An excerpt:
…we are in the habit of collecting reasons why things might be bad ideas… With a library of reasons to reject in hand, we can do simple pattern matching to find reasons to reject most anything. We can thus continue to pretend to be big fans of innovation, saying that unfortunately in this case there are serious problems.
The semiotics of rejection neatly explained: The “sign” (the new idea) “calls up” (indexes) a “library” of (preformed) “reasons” to reject it.
FIML practice, of course, greatly alters the status quo of how partners communicate with each other. And that changes how partners understand each other and themselves. And that is a huge benefit, but why believe me?
