Efficiency, at least the way I’m using the term, is relative to our values. If we don’t want to use the most efficient method possible to achieve something, then something about that method causes it to have a negative term in our utility function which is just large enough to make another alternative look better. So then it really isn’t the most efficient alternative we have.
The only thing we want is to get the things that we want in the most efficient way possible. In other words, to be instrumentally rational.
If what we want is to reach our wants without using the most efficient way possible, what method should we use?
