Another bite of dead rat on raw onion, anyone :-) ?




pahunkboy -> RE: Is the human species getting smarter? (9/10/2007 9:23:53 AM)

..likeminded folks on a cruise ship might be more of the cambridge/sillicon valley crowd.  rat death folks- maybe made road kill stew.

being that alcohol knocks out the frontal portion of the brain, that could explain the expanse.  the study is co-incidental- more needs to be condierred.

todays folks are entirely dependent on the grid for survival- that is not idividual smart- it is collectively smarter tho.  assuming the grid functions 24-7 which it did not on 9-11.

the appearance it that we are smarter- but we also have more nonsense and useless data to process 24-7. such noise tolls the soul.  sorta how they say eye sight- more folks needed glasses in teh city due to not looking far into the horizon.

the grid is smarter.  the humans are pretty much rats in a cage! [politics and tv...and teh dumbing down of the Internet]

There have been people in the historical record who claimed to have found connections between skull measurements and similar to things like intelligence and even morality.......eyes too close together indicating kleptomania for instance. In practice however such ideas have never been proven true and often lead to unacceptable acts of intolerance.

A few random thoughts.

My limited understanding of evolution, is that as our brains evolved, they required a higher number of calories to sustain it.  The human brain consumes about 20 watts (400 calories a day, roughly 1/5th of our dietary intake.)  In beginning to add meat to supplement our diets, our brains were fueled to become larger.. making us more adept at using tools and cooperative social behavior, securing more meat, allowing greater calorie intake... creating an evolutionary cycle.

Technology is a Pandora's box.  Once out, you can't put it back in.  Our world today doesn't have electric ovens and airplanes and cancer treatments because we've just 'gotten smarter'; it's because every single technological advancement is just that; a step forward.  Today's economy is driven and fueled by technology.  In a way that never existed before in time, technological advances have inherent value.  The more specialized an economy is, the more prosperous all the people within it become.  A quick look at the way technology is used in Africa, parts of Asia, or Latin America compared to Europe, Australia, or North America quickly illustrates these differences.

But as suggested, cavemen and bush people aren't necessarily capable of surviving off the land alone any better than a New York City stockbroker; but if the stockbroker and the bushman were both told that six months from now they'll be dumped in the middle of a forest to live for a year, my money is on the stockbroker to survive the ordeal, simply because his life has depended on being able to learn and make use of tools.  He could do consultations, research, and get the best minds availible to tell him where and how to hunt, what to eat, and how to survive.  The bushman may have survived in a primitive fashion his whole life, but always dependent upon his own society; his fellow hunters for example.

The ability to use technology reflects our ability to adapt.  Adaptation is necessary for a society to grow.  The question of 'if a society should grow,' is a far different moral quandry.

I had always been taught that the opposable thumb and development of language were responsible for the development of human intelligence.

Read a study a month or two ago (probably in Discover) which posited that the reason people developed the
sort of abstract reasoning skills was based not in either of these two aspects of our existence, but in our
simian propensity for throwing objects.  Apparently, the brain needed to develop to a certain extent to deal
with projectile trajectories.

So the next time some monkey throws crap at you at the zoo, tell them the secret is to beat the rocks together
to make fire.

Lordandmaster, I just looked up the Flynn Effect. the first two google hits. More of a slacker look-up.

U of India has a course on Human Intelligence which says Flynn studied the rise in IQ scores based on national averages over the last 60 years. No direct links to cranium capacity but it does indeed seem to suggest an intellegence rise , insofar as people hold stock in IQ tests, which arn't exactly the final authority.

In fact, Flynn's hypothesis was that "The hypothesis that best fits the results is that IQ tests do not measure intelligence but rather correlate with a weak causal link to intelligence." (Flynn, 1987). Based on the presence of the effect on nonverbal tests such as the Raven's Matrices, Flynn believes that the increase is actually an increase in abstract problem solving rather than intelligence. Flynn (1994, 1999) favors environmental explanations for the increase in test scores. " (U of Ind).

So why have abstract problem solvers gotten better in testable ways in the last 60 years? Wikki, not that Wikki knows anything, says there are several reasons:

nutrition

education (blacks got better access to schools during this time, for instance, and thus better at testing which affected the national average. Or the fact most people went to more years of better schools) 

smaller families/more parental involvment in knowledge transfer

heterotosis (apparently a fancy word for hybird vigor/the positive effects of interbreeding)

People are more used to and adept at tests in general and multiple chociers like IQ test's in particular

"the general environment is today much more complex and stimulating. One of the most striking 20th-century change in the human intellectual environment has come from the increase in exposure to many types of visual media." (although I've read some studies about Newfoundland country life to the contrary)


SOOOO the Flynn Effect says people are scoring better on IQ tests in the last 60 years not 500, but Flynn himself cautions all over the place against taking this to mean raw intellegence is going up.

Stephan:

I've read / subscribe to the same evolutionary theory. One salient illustration for me was the statement that while several members of the homo genus coexisted at differant times, most of the others dealt with scarcity by becoming niche eaters, while sapiens/neanderthals were omnivores. They died off over time and we didn't. The gamble was all or nothing-we needed to eat more than the competition in order to be strong enough get more in the long run. Alot like modern first world economies.

I don't know the difference between a calorie and a Calorie and I never did learn how that fed Watts. But thanks to a couple-year old issue of Scientific American I just read a few weeks ago and is still sitting by the computer,
I do know that modern chimps use 10% of their energy to power a 400 cubic centimeter brain, homo habilis used about 15%  to power a 600 cc brain, erectus 18% at 900 cc, and Sapiens a whoping  24% at 1350 cc.
---so the evolutionary progression of bigger brains requiring more food allowing for bigger brains is pretty cut and dried and well backed up by the physical record.

As Darwin famously said, "Everything I have seen, I gained by standing on the shoulders of Giants". I think it would be damaging to jump back down from the giant's tall back too quickly...and while we're up there on his shoulders, we are at his mercy in the same way we're at the mercy of tech others before us created.

-I've gotta disagree with you here, a little bit. This doesnt seem to be an absolute. Hell yeah (almost) everyone in the world is better off than they would have been 300 years ago, but specalization and tech and prosperity arn't distributed along egalitarian lines.
I grew up in a region widely regaurded as a post-industrial economic fallout zone. Since the factory jobs left, universities moved into the major cities and peoples kids became more educated and thus more specialized. But real incomes and buying power is on the decline. I know the region's farming industry is more specialized now, but the farmers who havent lost the farm are making less profit and more farmers are seasonal/farm-hand low-wagers. With China/Phillipeans/India, you might say that increased specalization and tech havent increased prosperity at the same rates they did in the industrialized world two hundred years before. With Africa, you could even argue that technology has forced both specializations which do not inrich and forced migrations to city-style poverty.

That is an awsome thought. Good point.

I don't know if you should do it up as a Robinson Curosoe, Bonfire of the Vanities, or SciFi, but that would make a great novel...

Personally, I think the reason technology continues to cause problems as well as solve them could be tied into that stock-broker. Just because he COULD survive better with the resources at his disposal doesnt mean he always WOULD. For one thing, he's probably allowed himself to become horribly out of shape. Of course he still uses the gym an hour a day in his luxury condo, but will his fabulous pecs catch him the deer? For another, he may not be willing to give up the twelve hour days long enough to prepare for the ordeal. Then again, maybe his power-walking seven blocks to see a prodom 3 times a week during lunch and his ability to schedule inordinatly long vactions could give him back his edge.
Yeah. I'd go with the stockbroker too.




Termyn8or -> RE: Is the human species getting smarter? (9/10/2007 11:28:23 PM)

Wow, you got me just about going with the stockbroker here. Of course there is the case of if he is doing well he should have a healthy lust for life. But which came first. Does he do well because he has a lust for life or does he have a lust for life because he does well ?

Would he figure it out, out in the wild ? I'd say he has a good shot.

Interesting point.

Aswad -> RE: Is the human species getting smarter? (9/11/2007 9:31:10 AM)

Actually, the average has dropped per generation, but the pertubance has increased, leading to an increasingly fat-tailed distribution, a sign that the per-generation drop may even be underestimated. There seems to be a smart group that keeps climbing steadily on its own, and a huge breeding pool of rabbits that are rolling slowly downhill, with a bit of overlap.

Mediocrity is more advantageous when there aren't significant external pressures, as is excessive breeding.

Then, every once in a while, some cataclysmic event comes along, wipes out the parts of the population that are in the "rabbit" group, and the population starts rebuilding from the tail end of the curve (those who survived, thanks to the wits to survive). Add a significant mutation here and there at random intervals, and you have the basic picture of the past few dozens of millenia.

Health,
al-Aswad.

Wow- do I not agree with this one.  Try reading "Guns, Germs and Steel" by Jared Diamond if you think that growing up in a primitive culture implies lack of intelligence.  Diamond's comment was that the natives of New Guinea were on average, some of the smartest people he'd ever met.  Our society doesn't kill off the dumb ones quickly the way a less technologically adept society does.
 
IQ tests have shown an increase in what the psychologists consider intelligence over the past century, but do you really think they're smart enough to figure out what intelligence is?  What those tests measure is a very small part of human intelligence- same with academic skills.  Hence I've met professors who were as dumb as a box of rocks, and some guys without a college degree who were plenty sharp.  Besides, there doesn't seem to be much of a correlation between brains and money earning ability, and money earning ability really gives you more choices in society about who and what you breed with.
