This is a contradiction in terms: IQ tests are very limited in what they measure and very much biased toward cognitive qualities SEIs do not have, which is a disgrace, because IQ tests do not measure the many qualities and forms of intelligence SEIs do have after all. So if you are SEI and truly scored an IQ of 150, you must be a true superhuman. So superhuman you surpass all other humans on this planet.
Or this 150 result is just the outcome of one of the many IQ tests on the internet that give way too flattering results.
