Bit of a tangent, but I don't think it's trivial to go from 'measurable biological data' to 'radical conclusions about politics and society'.
As for your example, I'm suspicious of the assumptions that
a) human beings can recognize 'stability' (pretty abstract) on a biological basis, and likewise react to it. How on earth would this mechanism work?
b) human beings haven't benefited from social stability for reproductive purposes
c) stability leads to extinction. Organisms only adapt because they aren't currently well-suited to their environment - 'adapting' doesn't provide 'strength' in its own right.
d) wars are about genetic strength rather than diplomatic, material and geographical advantages
Not to be rude, but if I were you, I wouldn't take my opinions from sci-fi writers. They write for entertainment, not for serious discussion. I'd also remember that practically every ideology has made a claim on 'measurable biological data' - even aristocratic societies looking at social animals like ants.
