University of Cambridge Cognitive Ability Test

Its an modern open-source and collaborative resource of IQ style questions for research studies. IQ has a lot of flaws, not the least of which is its usage outside of academic research, as a measure of job aptitude and hiring potential (spoiling its utility as a metric since the questions can be trained... setting aside its dubious usefulness as a hiring tool anyway).

It seems like ICAR is spending a-lot of effort to remain scientific, and i feel like a website like this goes against that by spoiling the test utility for future potential participants.

IQ is limited because it only looks at one facet and it generalizes a lot. Tests that look both into ability and aptitude, and especially those who split them by domain are much more relevant and applicable to real world scenarios.
