Subject: [mega] Application For Mega Membership From Brian Schwartz (*not
humor*)
Dear Sirs:
I believe that my test scores make me eligible for consideration for membership in your society.
In 1967, at the age of fourteen, I took the S.A.T. My score was 1593 -- 793 in English (Verbal) and 800 in Math. According to Ron Hoeflin's Fifth Norming of the Mega Test, see also the Prometheus Society's 1998/99 Membership Committee Report,section 8.5.6, in an average year only six people achieved a score of 1590 or higher. And, according to Ron Hoeflin's Sixth Norming, see also the Prometheus report, section 8.5.4, virtually all high school seniors in the 99th IQ percentile or higher took the S.A.T. Since there were three million seniors (aged 17) in 1967, a seventeen-year-old with a score of 1593 would have scored in the 99.9998th percentile.
But since I was 14, and a junior, my percentile rank would be higher. A 14 year old who does as well as a normal. average 17 year old has a ratio IQ of slightly over 120. At that level ratio IQs are more or less equivalent to deviation IQs. See:
http://www.geocities.com/ultrahiiq/Deviation_IQs.html
And a deviation IQ of 120 is about the 90th percentile (for both 15 and 16 SD) See:
http://members.shaw.ca/delajara/Qtable.html
This would put my score far above the 99.9999 level, eligible for Mega. But is the SAT an acceptable test for admission purposes? I believe it is.
The SAT has been given every year since 1926. Over a million people take the test every year. It is possibly the most carefully studied, normed, and scrutinized test in history.
The SAT correlates highly with g. (See A. Jensen, "The g-factor", N. Lemann, "The Great Sorting"(Atlantic Monthly,Sep.95), Prometheus Society Membership Committee Report, section 8.5) The hundreds of questions on the SAT all test mental ability (fluid g) and do not rely on learned knowledge (crystallized g)
Because of this high g-loading, Ron Hoeflin relied on SAT scores to norm his Mega test. Indeed, he believed that the SAT was valid at the 99.9999 level, but could not use it because he didnt have enough data: "I had hoped that with data on over 5 million SAT test subjects I would be enabled to refine my norms for the upper end of the Mega Test scale, in particular permitting me to pinpoint the one-in-a-million level more accurately. Unfortunately, this goal could not be achieved by means of this extra data since the number of SAT scores reported to me by Mega Test participants, 222, remains inadequate." (Sixth Norming)
I hope the above helps you with my application. I am honored to be considered for membership in your society.

The constitution of the Mega Society states that anyone will be admitted who
has "scored at the one-in-a-million level on a test of general
intelligence which is credibly claimed by its authors to be able to
discriminate at this level." I don't believe the authors of the SAT (the
Educational Testing Service) make this claim.
Although it would not be relevant for admissions to the Mega Society, Ron Hoeflin in his fifth and sixth normings of the Mega Test does not claim that the SAT discriminates at this level. He uses the SAT scores to estimate the sample bias of the Mega Test, and then extrapolates this bias to find the raw scores corresponding to true population rarity.
This is a controversial argument, but it is not the same as stating that the SAT can discriminate at the one-in-a-million level.
Here is a reductio argument explaining why the test authors must credibly claim that the test discriminate at the one-in-a-million level.
Suppose ten million people flip fair coins 100 times. Ten of these people will flip heads more often than anyone else. Is the intelligence of these ten people therefore at the one-in-a-million level? Obviously not; it was random chance that selected them.
Admittedly coin flipping has no g-loading. But the point is that the amount of g-loading matters. And that leads to the idea of the range of a test. Ron Hoeflin estimated the Mega range using some statistical bootstrapping, which is how the SAT was involved. That the SAT has some g-loading and that it was taken by millions of people is not enough to prove that it discriminates at the one-in-a-million level.
At the moment the members
have voted that the Titan Test is the only test accepted for admissions to the
Mega Society.

Subject: [mega] More From Brian Schwartz Regarding SAT
The [following] was written [by Brian Schwartz] before I was made aware of Chris Cole's reply...but I think it's relevant:
In case anyone raises this point... the SAT people put a lot of effort each year into re-evaluating and revising their test. They could have saved themselves a good deal of work each year by "dumbing the test down" to have a 99.9 ceiling...which they finally did in 1994. By putting in all that extra work (every year for over 50 years) to keep the ceiling at one in half a million, they were implicitly claiming that their test did discriminate at (or near) the 99.9999 level. And colleges knew this. When I applied to go to Oxford at age 16, their attitude was one of condescending if politely incredulous humor. But as soon as they learned my SAT scores, I was suddenly a serious candidate! (And was admitted...)
Chris Cole writes: "Ron Hoeflin in his fifth and sixth normings of the Mega Test does not claim that the SAT discriminates at this level. He uses the SAT scores to estimate the sample bias of the Mega Test, and then extrapolates this bias "
The reason Ron Hoeflin did not use SAT scores to discriminate at the Mega level was simply that he had too few of them. Of 222 people reporting SAT scores to him, only 4 had scores of 1570 or higher (the 1 in 150,000 level). Incidentally, of the 222 people who reported SAT scores to Ron, 4 had scores at the one in 150,000 level (1570) ...and 4 had Mega scores of 40...exactly what you'd expect if the SAT worked at that level. But the sample was too small.

Subject: RE: [mega] More From Brian Schwartz Regarding SAT
For admission to the Mega Society the constitution states that it is necessary
to show that the ETS (the author of the SAT) claims that the SAT discriminates
at the one-in-a-million level. We presume that the members would agree that any
such claim by the ETS is credible. So in order to be admitted Mr. Schwartz
simply has to document that the ETS claims that his score is at the
one-in-a-million level.We've already thoroughly discussed in Noesis why it is
unlikely ETS will ever make such a claim. I think the members understand the
concept of test range, and why it is not feasible with a test composed of fixed
questions to both spread out the mean and the tails. You can have one or the
other, but not both. Since the market is near the mean, for economic reasons
that is what the SAT does. Spreading out the tails is not something the ETS can
afford to worry about.

A more realistic figure for the ceiling of the old SAT is something like one in 150,000. They weren't interested in discriminating at that level; they wanted to leave some headroom so they could discriminate up to about the one in five or ten thousand level.

Those are very good scores. I'm not surprised.

More like one in 100,000.

Nope. The fiifth and sixth normings put the ceiling of the Mega Test way too high. 40 is about at the one in 100,000 level, too.
> But the sample was too small.
That's just one problem.

I don't think we need to be quite so literal. If *anyone* claimed that *credibly* it would be enough for me.

The SAT folks are usually at least in the right ballpark.

It would be necessary for the members of Mega to vote to accept the SAT.

Yes. That's a very good point. The SAT can't and doesn't try to discriminate at very high levels. No test discriminates well very close to the extremes of its range.
There are two other problems with Brian's application:
1. We should survey the available tests and decide what to accept *first*, then consider individual applications in the light of the standards we've established. I dislike seeing anyone's credentials debated publicly.
2. We don't accept age-corrected scores, nor should we. We want people who are actually smart, not those who've shown the potential to be smart when they're older.
(My estimates of the rarity level of various scores on the SAT are rough but I doubt that they're off by much.)
If Brian wants to join Mega he should take the Titan Test.
This brings up a question regarding our qualifying scores. The true one-in-a-million level on the LAIT would be 176, discounting ceiling-bumping effects; on the Mega it would be 46 and on the Titan 45. I think it's reasonable to allow one point on each test to compensate for ceiling effects (as we already do for the LAIT), so I think that our qualifying scores should be:
LAIT 175
Mega 45
Titan 44
That would mean raising our qualifying score on the Mega by two points and on the Titan by one.
What do others think?
Kevin Langdon
[After examining the summary of IQ's corresponding to scores on the Mega and Titan tests in Dr. Hoeflin's norms in OATH #23 (see Table 1) and the data contained in Darryl Miyaguchi's "Generic I.Q. Chart" at
http://www.eskimo.com/~miyaguch/combnorm.html
it has become apparent to me that the Mega and Titan tests are more closely comparable at the high end than I'd been led to believe, and therefore I now recommend 45 as our qualifying score on the Titan Test as well as the Mega Test.
We must adjust our qualifying scores if we are to continue to claim to discriminate at the one-per-million level. --KL]

[I disagree with Dr. Hoeflin's norms. I don't believe that it's possible to get enough more discrimination per item from the very small number of items that make the difference among near-ceiling scores to spread out scores in the far right tail this way. But there's no doubt that the Mega and Titan norms are closely comparable at the high end. --KL]

Subject: [mega] re-norming the tests
I would love to see an analysis of this point, essentially a debate on the proper way to bootstrap the norms on these tests. I admit that I think the arguments have all been made before somewhere, but it's my impression that they have been spread out in space and time. Maybe I'm just getting old, but I can't remember the details. So I'd like to see them all made in one coherent fashion. If you submit your analysis for Noesis, I'm sure Ron would be motivated to defend his analysis. Maybe we'd have a couple of rounds of exchange, members who'd contribute their views, and then we'd have a vote and settle the matter.

Brian,
I think the issue here is about the range of the SAT, not how the Mega Society is run. The range of a test is a matter of science, which means it is mostly an objective fact. I agree that this discussion may be of limited interest to the general membership, but I'm happy to continue discussing the issue with you directly.
