But I suppose I was making the error of the Greek philosophers about the natural sciences -- actually, we can change our own minds, too, but that doesn't obliterate the science of economics. At any given moment, there does exist some concrete distribution for which there is a margin, even though supply and demand schedules are changing all the time.<br /><br />You're right, it does seem to apply more broadly than just to evolution.Scotthttps://www.blogger.com/profile/12915297057336831151noreply@blogger.comtag:blogger.com,1999:blog-7225373.post-40901140272674971492013-04-19T05:57:42.447-04:002013-04-19T05:57:42.447-04:00Well, I didn't call it economics, but *much* o...Well, I didn't call it economics, but *much* of economics can be applied to non-human critters in a very straightforward fashion.

I'm serious. <br /><br />I understand your thinking here, and it is interesting (as is the correlation), but it isn't economics. Maybe an "economics ... of such and something or other", but not economics in terms of human thought (which is the realm of economics). <br /><br />If you want to get even more involved, take a look at specific birds, such as pigeons. Or, for 4-legged land creatures, raccoons are a good study. But I wouldn't call that economics.

I specifically told my class I was making no behavioral assumptions about the birds. The behavior could be completely freely chosen: nonetheless it is the birds at the edge of the range of choices who will push that range out further as human behavior changes. Marginalism seems to apply to life, whatever cognitive assumptions we make about various forms of it.gcallahhttps://www.blogger.com/profile/10065877215969589482noreply@blogger.comtag:blogger.com,1999:blog-7225373.post-81460756948285095202013-04-18T17:28:08.816-04:002013-04-18T17:28:08.816-04:00That's a pretty neat illustration.

But it treats the birds purely as objects, rather than also as subjects (i.e., it makes their behavior a purely a function of genetics and dismisses the possibility of free-will).<br /><br />I suspect there is a subjective element to it as well -- the birds can, to a degree, choose to adjust their own behavior, depending on the circumstance. Maybe a worm couldn't choose, but I'll bet a bird can.<br /><br />(To take it further, there might also be epigenetic phenomena -- maybe the experience of living in city vs. country alters gene expression. If you grew up way up in the Andes, you'd probably be a stocky little guy with enormous lungs and a lot of iron in your blood -- independent of natural selection or your own freely chosen attempts to acquire such traits. Maybe the lower stress environment of the city causes changes in gene expression that let the birds relax and experiment with risky behaviors they otherwise wouldn't try.)<br /><br />I'm probably taking this analogy way too far...Scotthttps://www.blogger.com/profile/12915297057336831151noreply@blogger.com
