Yep, past 140 is where they start to get unreliable... anyways isn't 180 like 99.999999999% of the population? I don't think the Standford-Binet or the WAIS get that specific.
actually, 99.9999999th is about the highest class for a society right now, and that is the giga-society.
check this out (also from that site, you guys really should read it:
"
In 1921, Lewis M. Terman, by means of teacher selection and multiple testing, identified 1,500 of the most intelligent children in the California school system. His aim was to follow this group of gifted people throughout their lives and observe their achievements in the widest possible sense. He was interested not only in their educational and vocational successes, but also their hobbies, interests, reading habits, health, and many other things.
As children, the Terman group was larger and heavier than the average California child; they matured earlier and their health was better. They averaged one full grade ahead of their contemporaries in grade placement, while at the same time more than half of them had mastered the curriculum a full two or more grades beyond their classmates. There was no evidence that the gifted group was cursed with any compensatory weaknesses, but because they did prefer older playmates and more solitary play, they were sometimes reported by others to be "queer" or "different". Nevertheless, they were not thought to be any more unsociable or unpopular than other children.
As adults, most went on to college and many earned academic distinctions. Delinquency and crime were both below average in frequency, and suicide rates, marriage rates, and age of marriage were the same, or nearly the same as those of the general population. The group's war record, occupational success, and income was clearly superior. By age 35, they had published 90 books and 1,500 articles. By age 45, the group had produced 2,000 scientific papers, 230 patents, and 33 novels, as well as many shorter literary works. All in all, the general picture was one of high scholastic achievement and pronounced occupational success.
Terman entitled his longitudinal research project Genetic Studies of Genius, and quite clearly, this was exactly what Terman expected it to be. But soon the evidence began to mount that IQ was not the index of genius that Terman had first thought. There was no John F. Kennedy, no Robert Oppenheimer, no J.B.S. Haldane, and not even a Henry Ford. Clearly, IQ was the single most important variable ever discovered for the prediction of achievement, but it was just as clear that genius was too elusive to be captured by the IQ net alone.
Finally, in the 39th Yearbook of the National Society for the Study of Education Part I, pp. 83-84, Terman made a most astonishing statement. "Our conclusion is that for subjects brought up under present-day educational regimes, excess in IQ above 140 or 150 adds little to one's achievement in the early adult years." A little farther on he says, "The data reviewed indicate that, above the IQ level of 140, adult success is largely determined by such factors as social adjustment, emotional stability, and drive to accomplishment."
In other word, an extremely high IQ conveys no practical advantages at all."
"...for individuals in a profession known to require high intellectual prowess there is, nevertheless, a wide variability around the median IQ of 125.5. The actual range of Full Scale IQ on the WAIS for these young physicians is from a low of 111 (77th percentile) to a high of 149 (99.9th percentile).
Matarazzo goes on to say, "Another point which is well understood among the few currently growing group of specialists in this country who deal primarily with the assessment of individuals applying for entry into medicine, law, graduate nursing, physics, economics, psychology, English literature, graduate business school, and a host of related scientific and humanistic disciplines is that, on the basis of a purely intellectual index, such applicants are so similar as to have come from the same population.
Currently practicing physicians are also similar to these young medical students in Full Scale WAIS IQs. (Matarazzo and Goldstein, Journal of Medical Education, 1972, 47, 102-111)
Holt and Luborsky in Personality Patterns of Psychiatrists, 1958, p. 40, reported that the "Average Wechsler-Bellevue Scale of Adult Intelligence was 128" ... "Scores ranged from 110 to 145. IQ was not decisive in gaining admittance; the average of those accepted was only slightly higher than those who were rejected. The average verbal subscore was 131 with a range of 115-145."
"
basically most of this studies say that typically, and iq over 140 wont help much in business success.... interesting?
