It's certainly a counterexample to "human optimism, ingenuity, and
technology inevitably solve our worst problems". When I visited
the ruins of the old city outside Jerusalem, it became obvious
that people have been living there for over 4,000 years, yet still
haven't figured out how to get along.
I doubt we have any more optimism or ingenuity, and technology hasn't
done much beyond widen the scope of the battlefields. Could there be
such a thing as having too much history -- "they forget nothing, and
learn nothing"? But let's be optimistic; maybe biotech can help, and
we can follow Galton...

Galton was heavily into eugenics -- if formal breeding programs have
been so successful with other mammals, why not apply them to humans?
Domesticated animals are generally more docile than the wild types, so
perhaps we could breed in a /heerdenmoral/ to replace the /herrenmoral/
that leads to conflict.
Why would he have been creating composite faces? It's pretty standard
in the breeding world to attempt to shortcut genotype evaluation by
evaluating phenotypes instead. It's only been in recent years, for
instance, that it's been discovered that many of the visible traits in
traditional prize bulls had zero (or even negative!) effects on the
efficiency of milk production in their daughters (in a factory dairy
environment, at least).

So Galton discovered that composing hybrids of phenotypes produced
superior (better looking) phenotypes. Is there any relation between
"better looking", and fitness? According to the journalists, yes:

In cereals the superior fitness of averages is clearly shown;
hybrid vigor results in higher yields, and purebred lines
which consistently reproduce themselves experience inbreeding
Can one outcross forever? Apparently not; yields decline in
successive generations from the original cross. (entropy/drift?)
Therefore, we need to maintain the low-yielding purebred lines
as sources which we can cross to consistently produce desired
This is where the stupid idea comes in: if we wish to breed for
high fitness humans, and choose to do so by making sure our
"working population" is composed of vigorous F1 hybrids, how
do we maintain a supply of the "show population" despite their
fitness disadvantage? As usual, FoRK answers:

Now, technology may insulate, but since everything is supposed
to be reducible to financial terms, a suitable pile of the ready
is probably an appropriate handicap. For any of our progeny who
we feel are unable to compete fairly on the basis of genotypically
depressed fitness, we can award a handicap in the form of a large
If all this eugenical activity not only ensures lasting peace in
the mideast but also a population of supermodels, there will be
an easy answer to the question posed by:

"Silver spoon", being the finbiotech tool of choice, as applied
according to this modest proposal, would be the nonderogative.
Yours for transhumance (sic),
 the only city I have been where architects take "fire fight"
as a design consideration.
 yes, many of the good ideas we have about getting along are
from that area, and they're even simple, but to expand on
the domain of Clausewitz' observation:
"everything in peace is simple, but
the simplest thing is difficult"
 Orwell in _Animal Farm_ tells a story in which the pigs
pursue their interest in maintaining their bretheren in
domestication. Application to human society was left as
an exercise for the readers.
 but what if we've already domesticated man through selection
for succesful living in village and city?
 Of course, generally one evaluates the entire conformation, not
just the head, and hotornot scores reflect avoidance of pinning
exhibitors who cannot be fully judged:

 Another possible explanation is simply scarcity -- we judge
as beautiful that which is not common. Langlois takes one
tack against that,

but extremes need not be extremes of expression. In a 1d
space, there will be many samples at the mean of a normal
distribution (the famed bell curve), and very few at the
edges. But move to multiple dimensions (and the space of
facial features and their relationships has at least a few
thousand dimensions), and most samples are at a distance
from the mean point. So being "average" in all ways
will be very rare, and taking the mean of several poorly
correlated commonly found samples of the population will
give a result rarer than its precursors.
 if this is not obvious, consider either chi-square tests,
or the surface/volume ratios of n-spheres as n increases,
or the virtue of portofolio diversification.
 Application of this stupid idea to the historic roots
of high culture, university endowments, etc. is left
as an exercise for the reader.
