Hi Jim. What about the intransitivity of ranking priorities in groups,
(ie., Kenneth Arrow's so called "impossibility theorem",) where
insincere voting is used by group members to pursue their own
interests?

Frequently, the outcome in such situations is that everyone in the
group gets their least favorable ranking of priorities-a situation
that has been empirically verified.

In such cases, it is not so clear that pursuing self interest
contributes to promoting general good.

BTW, the 1956 House vote on a bill calling for federal aid for school
construction is an often cited case where insincere voting occurred
[Riker]. The battle between R. Nixon and the Supreme Court over the
White House tapes is another [Brams]. Steven J. Brams elaborates on
many more in "Paradoxes in Politics", The Free Press, 1976. (The
problem concerns what is meant by the term "self interest". If I
really want the group to do something, but doubt that I can muster
enough votes to get it through, and I really don't want something else
to be passed, I will cast my vote to preclude that something else
being passed, instead of for what I want-since voting for what I want
would be an inconsequential gesture. Note that I did not vote my
preference, but voted against my least preferential choice-which is
rational behavior under the circumstances. Lying maybe-but rational
nonetheless.)
