Are humans getting dumber?

That's because a series of mutations affecting the estimated 5,000 genes controlling human intellect have crept into our DNA, says Gerald Crabtree, a geneticist at Stanford University, whose findings were published in the journal Trends in Genetics. And modern society allows people to focus on becoming an expert in one thing — we no longer need a wide breadth of knowledge or even cognitive ability in order to thrive.

"I would wager that if an average citizen from Athens of 1000 BC were to suddenly appear among us, he or she would be among the brightest and most intellectually alive of our colleagues and companies, with a good memory, a broad range of ideas, and a clear-sighted view of important issues," Crabtree writes.

"Intelligence doesn't play as significant a selection in our present, supportive wonderful society," he says. Humans no longer (or rarely) die because they were unable to outwit a predator. Humans were much more likely to die due to "lack of judgment" thousands of years ago, he says.

1000 BC hell, I’d wager that if a person born 150 years ago were to miraculously appear among us he’d make most of the public school educated in this country seem more fit for a primate exhibit in a zoo than voters in a self governing representative republic.

Remove nature and you get complacency. The culture of today is accelerating this with their hand out mentality.

In the 1950s Nobel Prize winner Shockley showed that birthrate is inversely related to IQ. The higher the IQ, the lower the birthrate.

I think the dims are happy with this trend.

Any Freeper women who would like to help me breed a new generation of highly intelligent conservatives should be aware that I am single....and at least part of darth is biological!

Pure tripe. If our predecessors were so intelligent, why didn’t they figure out that the Earth orbits the sun? What about something as simple as E=MC2? Where are the airplanes? The automobiles? Heck, even a freakin’ steamboat?!? How about a microchip, or even a simple diode?

Lasers?!!—Eight O’clock, day one!

Mrs. Lurkin has letters written by one of her ancestors during the Civil War. Mind you, this was a young man who had been raised on a farm, but his diction, grammer and pensmanship is superior to that of most of today’s college students.

He obviously has never seen any of the ancient graffiti written on the walls of places like Pompeii. Here are some of the nastier bits. NSFW unless you are an archeologist.

Otherwise, when Saddam ruled Iraq, the place was still littered with a vast number of Babylonian mud tablets used as correspondence between cities, which the Iraqis picked up and sold off for cash during the embargo.

Among other messages:

A teenage girl complaining that men are no damn good, and that they only want one thing.

A bill collector’s third warning message along with a note to the authorities in a nearby town that the guy was a deadbeat.

A student complaining to his parents that he needed more money, as all his peers had better clothes and stuff.

The trend in developed and developing nations is UP. This is largely a function of better nutrition and less childhood disease.

http://en.wikipedia.org/wiki/Flynn_effect

The Flynn effect is the substantial and long-sustained increase in intelligence test scores measured in many parts of the world from roughly 1930 to the present day. When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100 and their standard deviation is set to 15 or 16 IQ points. When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first. Again, the average result is set to 100. However, when the new test subjects take the older tests, in almost every case their average scores are significantly above 100.

Improved nutrition is another possible explanation. Today’s average adult from an industrialized nation is taller than a comparable adult of a century ago. That increase of stature, likely the result of general improvements of nutrition and health, has been at a rate of more than a centimeter per decade. Available data suggest that these gains have been accompanied by analogous increases of head size, and by an increase in the average size of the brain.

I have two long letters written by one of my great-grandfathers during the war in 1861 and '62. He was a farmer turned Confederate soldier. His writing is the same as you describe in your wife's ancestor's letters. It is a real eye opener.

"allows people to focus on becoming an expert in one thing — we no longer need a wide breadth of knowledge"

That answers the question. The knowledge is just deeper, not wider.

Hell,we've probably absorbed more by the time we are five years old than any Athenians did in a generation.

Impeach the kenyan or secession.

Yep. A lot of dumb people out there with smart phones.

Yeah, but what about those smart phones, eh? Who the heck makes these things? We make a big deal about Newton and Einstein, but what about "Moore's Law", which essentially predicted and predicts the exponential growth in the power of Silicon technology. How can this be? How can you predict such a rule which has lasted now for decades? I mean, WHO ARE THESE GUYS?

I have been wondering for a while if some of the stupidness of people isn't because of the degeneration of the gene pool. I have also wondered if so many people losing it and killing or maiming other people isn't in part because people have lost some of the information in genes that regulates behavior in their brains. People, on the whole, seem to be getting worse all the time as far as not being able to think clearly or also cope.

Of course, the ancient Greeks did figure out that the earth orbits the sun, and well before that Homer described intricate mechanical contrivances depicting entire scenes of human activity ( Iliad 18. ) This chapter also introduces the word “automaton” to the modern age in reference to “tripod” lampstands which move by themselves in response to the wishes of the god.

In a way, it’s more astounding that they thought of these things when they were still so far from actually producing them.

True in some ways. The advent of books meant that we no longer had to keep a large amount of facts in memory.

In modern society, where class and social status is determined by profession and income, not by birthright and caste (as in medieval times for example) smart marries smart and not-smart marries not-smart. But the not-smart couples tend to birth more babies. So ...
