I think it would be more informative to ask people to take one specific online test, now, and report their score. With everyone taking the same test, even if it's miscalibrated, people could at least see how they compare to other LWers. Asking people to remember a score they were given years ago is just going to produce a ridiculous amount of bias.
Are there any free, non-spam-causlng, online IQ tests that produce reasonable results (i.e. correlate strongly to standard IQ tests)?
Mensa organizes cheap standardized IQ testing worldwide with many available dates.
I don't care for everything else they're doing, but at least that is a very valuable service to the world.
No chance.
To calibrate a serious IQ test, you need to test (1) many (2) randomly selected people in (3) controlled environment; and when the test is ready, you must test your subjects in the same environment.
Online calibration or even online testing fail the condition 3. Conditions 1 and 2 make creating of a test very expensive. This is why only a few serious IQ tests exist. And even those would not be considered valid when administered online.
And there is also huge prior probability that an online IQ test is a scam. So even if they would provide some explanation of how they fulfilled the conditions 1, 2, 3, I still would not trust them.
If you have a test thus calibrated, you can use it to evaluate tests that can't be calibrated in the same way.
Will this evaluation include giving both tests to many randomly selected people and comparing the results?
