The Flynn effect is the substantial increase in average scores on intelligence tests all over the world. When intelligence quotient (IQ) tests are initially standardized using a standardization sample by convention the average result is set to 100 and the standard deviation of the results is set to 15 points. When IQ tests are revised they are again standardized using a new standardization sample and the average result set to 100. However, if the new sample is tested using older tests in almost every case they score substantially above 100. The effect has been observed in most parts of the world at different rates. Similar improvements have been reported for other cognitions such as semantic and episodic memory.

haha and you ask me for the source of where i get this info from...
its called online research... maybe you should try it?
Must be where you live.

Calling BS lol, I'd say its Stockholm syndrome, You love your captor and feel for them, because they dont kill you & allow you to live.
As for IQ's, its quite obvious that kids today arent as sharp or quick thinking as there adult counterparts !
Fluoride is the anion F−, the reduced form of fluorine when as an ion and when bonded to another element. Both organofluorine compounds and inorganic fluorine containing compounds are called fluorides. Fluoride, like other halides, is a monovalent ion (−1 charge). Its compounds often have properties that are distinct relative to other halides. Structurally, and to some extent chemically, the fluoride ion resembles the hydroxide ion. Fluorine-containing compounds range from potent toxins such as sarin to life-saving pharmaceuticals such as efavirenz
Psychiatric symptoms, including insomnia, confusion, memory loss, and depression, are common, and more serious symptoms such as psychosis may occur in patients with compromised liver or kidney function. Rash, nausea, dizziness and headache may occur Efavirenz can cause birth defects and should not be used in women who might become pregnant Safety in children has not been established Use of efavirenz can produce a false positive result in some urine tests for marijuana
In the United States, a black box warning (also sometimes called a black label warning or boxed warning) is a type of warning that appears on the package insert for prescription drugs that may cause serious adverse effects. It is so named for the black border that usually surrounds the text of the warning. A black box warning means that medical studies indicate that the drug carries a significant risk of serious or even life-threatening adverse effects. The U.S. Food and Drug Administration (FDA) can require a pharmaceutical company to place a black box warning on the labeling of a prescription drug, or in literature describing it. It is the strongest warning that the FDA requires
Contradictions to the Flynn Effect This was an example of what the Flynn effect tried to suggest. However, there have been certain contradictory studies emerging, which undermine the Flynn effect to a certain extent. For example, researchers Herrnstein and Murray had a theory which states that the Flynn effect is not observed for all levels of ability, and in fact it's more predominantly observed in people with low abilities. In other words, people with low IQ levels have demonstrated a noticeable rise in their abilities as compared to higher IQ people. Thus, for instance, people with learning disabilities might show a steep rise in IQ in accordance with the Flynn effect, but the same change might not be observed for people with a higher IQ. It is a characteristic of the lower segment of IQ and not clearly demonstrated in people with better cognitive abilities. There have been studies like the one conducted by Teasdale and Owen in Denmark, which suggest the end or stagnation of the Flynn effect. In their assessment of Danish youth for the period from 1959 to 2004, the progression seemed to have reached a plateau and receded. The latest performance pattern was pretty similar to that observed before 1990. The Flynn effect explains the rise in general IQ level over a period of time. But in order to successfully establish the credibility of this effect, more research and a generalized study by different researchers needs to be done.
A Commentary on the Flynn Effect and Other Points: From what I have read in the scholarly literature, nobody denies that the Flynn Effect exists. Throughout the world, data has shown that it is almost invariable that modern generations do better on old IQ tests than earlier generations did. Although the Flynn Effect continues to be surrounded by, and is central to several controversies (for example, about the meaning of IQ, or g, or the validity of IQ tests, or how the Flynn Effect can be explained) the Flynn Effect itself has survived all scepticism. James R. Flynn himself was perplexed by his findings (and he questioned the validity of IQ tests). He was the one who brought up the rhetorical ploy of suggesting something to the effect of that if IQs have been increasing by 3 points per decade, the ancient Greeks must have been retarded to an absurd degree. One point that Flynn and others gloss over is that there is no evidence, and no one is claiming that these IQ gains have existed forever. Indeed, one of the theories that probably explains much of the IQ gains is Richard Lynn's Nutrition Hypothesis (The Role of Nutrition in Secular Increases in Intelligence, Personality & Individual Differences Vol. 11, No. 3, pp. 273-285, 1990). Lynn claims that nutrition improvements would explain both the increases in height and in intelligence. In the above paper Lynn wrote: For the last 2000 yr data on heights of adult males in Britain have been collected... The broad trend is that height has been constant at a mean of approx. 172 cm up to the cohort born around 1930. From this date onwards height has increased. It seems reasonable to infer that brain size and intelligence were approximately stable for about 2000 yr up to around 1930 and it is only in the last half century that the increases have occurred.

It would at least be nice to have a source for your claim about fluoride. Not that I don't believe you, but I could just be like BIG MACS MAKE YOU IMPOTENT!!! and without a source, it's just some dude making crap up.
