> Our systematic review of 445 benchmarks reveals prevalent gaps that undermine the construct validity needed to accurately measure targeted phenomena
Intelligence has an element of creativity, and as such the true measurement would be on metrics related to novelty, meaning tasks that have very little resemblance to any other existing task. Otherwise it's hard to parse out whether it's solving problems based on pattern recognition instead of actual reasoning and understanding. In other words, "memorizing" 1000 of the same type of problem, and solving #1001 of that type is not as impressive as solving a novel problem that has never been seen before.
Of course this presents challenges to creating the tests because you have to avoid however many petabytes of training data these systems are trained with. That's where some of the illusion of intelligence arises from (illusion not because it's artificial, since there's no reason to think the brain algorithms cannot be recreated in software).
