I had not previously though of it as a "collapse of wave function",
but in my younger years I had thought that the discovery of life on another planet
would immediately bring the entire world into a unified front
to create a "defense" against our common enemy.
So, I imagined that we could create this "world peace" if our government
secretly made some non-earth alloys of metals and a created a news story
that "aliens had crash landed in some distant place"... al la Roswell, NM
But more to Z's point, given that the US has 2 political parties and strongly resists
attempts to create a political world of 3 or more, the way of change
involves replacement of parties (a la today's Republicans vs Tea Party-ers).
This may be embedded in our nature due to our legal system.
We have attorneys that "represent their client" and prosecutors that
represent the State, each doing their best (or worst) to prove their point.
Any sort of acknowledgment that the opposition may be correct is unspoken.
This is based on the assumption that "right" and "justice" will come out
of each side doing their best a battle-to-the-death.
