This previous thread proved that this is a legit online IQ test.

>What did we learn about the psychtests.com IQ test?

1. The IQ test has a strong correlation with proctored IQ tests like WAIS-R and Stanford-Binet.

2. Raw IQ scores (SD 18.67) are converted to a standardized IQ score (SD 15) and then reported to users. This means that your reported score matches what you’d get on an SD 15 test like the WAIS-R (4.4 in Compliance with APA Standards PDF).

3. Because the test’s samples were gathered online, sampling bias was tightly controlled for (7.10 in Compliance with APA Standards PDF).

>What did we learn from anons in the previous thread that took the test?

1. A majority of anons reported receiving scores comparable to scores they had received on proctored IQ tests.

2. The corollary to the Dunning-Kruger Effect was once again confirmed as many test takers who scored highly on the test did not accept their scores and argued that they were artificially inflated, falsely presuming that what they found easy was also easy for those of lesser abilities.

>What does this mean for IQ testing?

1. While people interested in determining their IQ should always take a battery of IQ tests and compare their results across all tests to calculate a composite score, an online IQ test can be just as valid as one administered by a licensed psychologist so long as it is properly developed and standardized.

2. The “there are no valid online IQ tests” meme is just that- a meme.
