Of the dozens of people who took the KAMIKAZE, at least 14 have self-reported math SAT scores. Some people took the KAMIKAZE before an answer key problem with the Dice item was corrected and so, for the purpose of the norming, I corrected the scores of those who were unfairly penalized so the norming would reflect the corrected version of the test.

I also deducted a point from those who were unfairly boosted by a brief scoring error (when I added a research question for comments, this added a point to everyone taking the test until I quickly spotted the problem & corrected it). With these corrections in mind, here is the raw data:

In my first norming, I converted all math SAT scores to the pre-1995 scale and then converted to IQ equivalents using 1980s norms but that seemed to produce inflated results, especially at the low end. This time I converted math SATs to IQ equivalents directly, using estimated means and SDs for the time period.

To get IQ equivalencies for the KAMIKAZE, KAMIKAZE scores and math IQ equivalents were both ranked from highest to lowest and equivalent ranks were equated:

The mean and standard deviation of the KAMIKAZE in this sample is 7.9 and 3.8 respectively while the mean and standard deviation for SAT derived math IQ is 134 and about 11. The relationship between raw scores and IQ looks fairly linear, so one can probably just use the following equation:

IQ (U.S. norms) = (KAMIKAZE score)(2.79) + 111

If this extends to the extrne a score of 0 would put you around the level of the average American university grad. A perfect score of 17 out of 17 would put you just below Prometheus level.

One red flag is the correlation between KAMIKAZE scores and math SATs is 0.0005. Technically this calls into question the whole logic of using math SATs to norm KAMIKAZE scores. However the correlation jumps to 0.43 when I remove everyone who took the old (pre-1995) SAT from the sample. This makes sense because old SAT people have the highest SAT derived math IQ scores because they took the test back when it had as huge ceiling, and yet because these people are now oldish, cognitive decline impairs their KAMIKAZE scores.

To adjust for age, I would advise readers to give themselves a bonus of 0.17 IQ points for every year over 30.

Next, I ranked the items in order of difficulty based on the percent of this norming sample to pass them.

I just scored an 11 on the K. I scored an 11 on the T, yet my verbal IQ is higher. It is far easier to devise a reliable measure of math iq than of verbal iq. Brings to mind that silly Dr. Dre question. In the case of an amateur-devised test, we should expect the math inventory to be more reliable.

in math there is only one right answer. in verbal it is left to your interpretation. consider the fact that the derivative of specificity is grander than expected.

Also, curious if answers that included units, e.g., ‘mph’, would be recorded as incorrect. I am satisfied with an 11, but the score struck me as perhaps a point too low.

I know Franz Ferdinand was killed by the Black Hand, which led to WW I. Don’t know who Lucretia was. The answer to that Dr. Dre question is someone everyone in North America has heard of. The man of culture thing is just a meme. Didn’t mean to offend. I agree that verbal tests are hard to construct without heavily loading on familiarity with the creator’s background, but my test is pretty eclectic. There is some value to be gotten from open-ended verbal questions beyond measure of “cognitive ability.” For example, we may infer that someone who is dismissive of the Dr. Dre question is “snobbier” than average.

I had in mind ‘revolution’ as the answer to that analogy. The assassination of the archduke incited a war (WWI). The ‘Rape of Lucretia’ incited a revolution (leading to the formation of the roman republic, so it goes). Insurrection or rebellion also works (if the question is passable). I consider the label ‘snob’ to be a title of honor in the contemporary west.

got 5/17 on it. Very challenging thought I’d get higher. Did I get things incorrect by saying miles per hour and whatnot? It would put my math IQ in the mid 120s and 130s region hahaha

The test instructions say not to bother with units and that just the number is necessary, maybe they need to be edited to make this clearer PP (as well as changing the scores of any submissions that did give units) like “do not put units in your answers – just write the number; e.g. write ’10’ instead of ’10 mph'”

Welp 8 on this and 12 on TAVIS. I suspect tests like these just don’t accurately measure my intelligence anymore because of years of test taking. Still a nice ego boost, haha.

Wow. My score was 14, which using the formula gives an IQ of 150, or 3.33 SD above the mean. (I get another couple of points by using the suggested age correction of 0.17×15=2.55 and English is a second language).
Do you really think a score of 14 implies a math-IQ 3.33 SD above the mean?
Naturally, I would like that to be the case, but I must say I kind of doubt it.
It seems a bit high.
Anyways, I hope more people take the test and provide usefull data for future normings.

said:Which standard deviation is applied in the IQ-score derived by the formula ?:

IQ (U.S. norms) = (KAMIKAZE score)(2.79) + 111

Can we assume it`s 15 or have you perhaps used 16 or 24?

Thanks for an interesting test and blog btw.
