> Since AI vision is not yet good enough, it’s possible that one reason the AIs do relatively poorly on this new test is because the verbal descriptions of the questions are not written as well as they could be, and further research could include multiple wordings of the questions, written by different people, to get a sense of how sensitive the AIs are to how the questions are described.
A more parsimonious theory might be that it had the other IQ test in its training set.
Still, even at that it's an impressive result; it having an actual IQ if about 100 would already be pretty substantial.
