Surely both of you (and others) realize that a lot of stoners smoke because we're surrounded by people significantly, and often, painfully dumber than ourselves? I mean, that's kind of the point - a little recreational stupidity makes you calmer, relaxed, and more apt to be able to deal with the monkey house into which you're born.

Since you're a lazy jackass:

Scientific achievements

Sagan's contributions were central to the discovery of the high surface temperatures of the planet Venus. In the early 1960s no one knew for certain the basic conditions of that planet's surface, and Sagan listed the possibilities in a report later depicted for popularization in a Time-Life book, Planets. His own view was that Venus was dry and very hot as opposed to the balmy paradise others had imagined. He had investigated radio emissions from Venus and concluded that there was a surface temperature of 500 °C (900 °F). As a visiting scientist to NASA's Jet Propulsion Laboratory, he contributed to the first Mariner missions to Venus, working on the design and management of the project. Mariner 2 confirmed his conclusions on the surface conditions of Venus in 1962.
Sagan was among the first to hypothesize that Saturn's moon Titan might possess oceans of liquid compounds on its surface and that Jupiter's moon Europa might possess subsurface oceans of water. This would make Europa potentially habitable.[15] Europa's subsurface ocean of water was later indirectly confirmed by the spacecraft Galileo. The mystery of Titan's reddish haze was also solved with Sagan's help. The reddish haze was revealed to be due to complex organic molecules constantly raining down onto Titan's surface.[16]
He further contributed insights regarding the atmospheres of Venus and Jupiter as well as seasonal changes on Mars. He also perceived global warming as a growing, man-made danger and likened it to the natural development of Venus into a hot, life-hostile planet through a kind of runaway greenhouse effect. Sagan and his Cornell colleague Edwin Ernest Salpeter speculated about life in Jupiter's clouds, given the planet's dense atmospheric composition rich in organic molecules. He studied the observed color variations on Mars' surface and concluded that they were not seasonal or vegetational changes as most believed but shifts in surface dust caused by windstorms.
Sagan is best known, however, for his research on the possibilities of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation.[17]
He is also the 1994 recipient of the Public Welfare Medal, the highest award of the National Academy of Sciences for "distinguished contributions in the application of science to the public welfare".[18] He was denied membership in the Academy, reportedly because his media activities made him unpopular with many other scientists.[19]

Smoked pot three times in high school, got caught each time, by the cops, my parents, and school, respectively.

Didn't toke up again until second semester sophomore year. Was pothead (smoked and played lots of video games and watched movies) for two years of college, graduated with shiatty GPA.

Stopped smoking again for a few years. Came back to it to help me work out, stretch, and dance. Now its a stimulant. Use much less frequently, get incredibly creative after smoking and stretching. Was totally doing it wrong in college.

There is a reason why Michael Phelps, the Canadian Snowboard Team, Arnold Schwarzenegger, and many other elite level athletes smoke cannabis. Its because it is a ridiculous stimulant when combined with anaerobic exercise to mover the cannabinoids through their metabolic pathways and an acidic catalyser to disengage all the sticky molecules and allow them to seek out the cannabinoid receptors throughout the peripheral nervous system. It awakens an incredible amount of lasting energy, not just kinetic energy, but creativity coupled with rhythm, balance, and extremity-eye coordination.

Its not widely known or appreciated, sadly, but its an incredibly awesome way to use the herb. Try it sometime...

You claim he contributed nothing "original" to science. Multiple examples of his unique contributinos were posted, peer reviewed and confirmed with later research. You claim he was a "pothead," a derogatory term used to describe people who are unproductive and use marijuana to the detriment of their lives. Both of those definitive points are obviously incorrect.

You are pedantic, shallow, and boring. You add nothing of value to the conversation.

kruppz: So that's why I.Q. tests were deemed a myth a few weeks ago.


From further reading, including the release by UWO itself, this seems to be focused on corroborating what is known in research rather than bringing any shattering revelations to light. Will check into the study shortly, but I am imagining the release and articles suffer from basic misconceptions about intelligence testing, and therefore whatever information gleaned from the study are placed through this filter. No one in the research believes IQ is a measure of all intelligence, but IQ is a good measure of some facet of intelligence, receives reliable and valid scoring, and higher IQ is strongly correlated with higher universal aptitudes while higher specific aptitudes are strongly correlated with higher IQ.

The ideas IQ represents nothing of intelligence and IQ represents everything of intelligence are both quite and, for my field, painfully wrong, but the former is further wrong.

Ayn Rand's Social Worker: I always wondered about what the best ways to test other forms of intelligence than IQ.


Let me break from this notion of there being "other forms of intelligence" because what you follow with seems taken from Gardner MI theory. Not to say intelligence is a singular construct, but rather than being distinct forms of intelligence, there are subsets which are related and interact. Will assume you are an educator since this seems to be where MI theory and learning styles take root, and allow me to say abandon the idea those are distinct forms of intelligence or learning; rather, there are several basic means to convey information in education (kinesthetic, tactile, reading, visual, auditory, verbal) and some people have pronounced domains which are favored by the environment and physiology. Gardner is intelligent and thought-provoking, but as a theory of intelligence his ideas fail due to g-theory which has broad acceptance and is compatible with theories of intelligence such as Triarchic by Sternberg. You do not have a bad musical intelligence, you have little development of the components for music such as rhythm and fine motor skills, and you do not have a good kinesthetic intelligence, you have advanced psychomotor development which could be said to cover gross motor skills and athleticism (notice, "psychomotor" is not a form of intelligence isolated in neurology but a general domain which helps us discuss subsets of aptitudes).

As to the actual question, intelligence testing of any type relates to development. We expect people of this age to consistently grapple with abstractions, motor function, sensory processing, etc., of this complexity, and this provides us a measure of intelligence. Several instruments do quite well identifying people who are extremely talented musicians or athletes but who do not perform in academic or memory tasks because those are taken into account. We could develop objective measures easily for a majority of aptitudes such as music (similarity and consistency of rhythm and tone on an instrument) or athletics (hand-eye coordination tasks and general athleticism), but the issue is those are extremely targeted and would require generations to resolve with the current matrices. I find my musically talented students perform well on the WISC, and when not, I sign off all the same; intelligence identifiers only matter as long as the world, such as education system, reacts.

Vangor: The All-Powerful Atheismo: If you're that smart you should know that such a specific IQ number is meaningless

Not meaningless, but not a precise descriptor of all cognitive ability either. I would say, of the qualms you posed, the nature of "intelligence" is the major concern surrounding intelligence testing today. Instruments have become far less biased, do provide reliable results, and measure a variety of facets of intelligence as standard. What still emerges as bias is historical levels of affluence which afford greater or lesser amounts of mental stimulation, essential as intelligence is developmental. Singular assessments are not to be trusted as precise but are useful diagnostically, and proper training with any instrument will allow you to note issues which would question any results (especially relevant for my assessment of children). Plus, I know of a dozen instruments, and none of them measure a single facet; KBIT is the simplest for estimation and covers two scores with two subcategories each.


I always wondered about what the best ways to test other forms of intelligence than IQ. For example, my musical intelligence is shiat, I have what my piano teacher kindly described as a "natural syncopation", meaning I can't hold a beat for shiat. So classical piano was almost impossible for me to do, but jazz fit me nicely. But then years later, I started doing break dancing and martial arts, and turns out my kinesthetic intelligence is phenomenal and my inability to incorporate steady classical rhythms is actually a huge positive in improvisational dance...

I also like thinking that we overly focus on the intelligence inside our brains, and not enough in our entire neural net. The kind of brilliance it takes to make the millisecond adjustments to juke a 250 lb lineman, or the muscle memory it takes to throw a bowling ball into the sweet spot or hit a golf ball into the wind within 15 feet of the pin or shoot a sniper rifle a thousand feet are all types of intelligence.

I guess sports and games are how we measure them...

It's not called DOPE because it makes you SMARTER.

Smoking ANYTHING is bad for you.

Marijuana users often (not always) become lethargic and apathetic. Like every generalization, there will be exceptions. Your mileage may vary, as they say. But generally, long term continuous use of anything consumed by smoking it cannot be good for the lungs.

And, because of the restriction of bloodflow caused by the smoke, some damage to the brain is predictable.

I am ambivalent about legalization, concerned about the billions pi$$ed away on police and prisons, and more interested in educating the public about the risks of smoking ANYTHING.

Yeah, it sure is. Because, according to the stoners, pot doesn't do anything to you at all and if you say otherwise they start to huff and puff and have another doobie and then huff and puff some more and have another joint and then huff and puff some more and then invoke the name of Carl Sagan.

Which, to a stoner, is all they need to prove their case. Unfortunately, the rest of us need a bit more proof.
