They don’t really tell you how someone works or thinks though. They just show you that the candidate thinks in one of a certain number of ways. If they can’t answer it could be down to a range of factors, that one hadn’t foreseen. The “thinking ways” that allow one to solve the problem can be considered to be socio-normative and neuro-typical; normally these fit white patriarchal modalities. The mental modalities that make it harder to solve such problems are those related to sequence memory weaknesses, comprehension weaknesses, stress factors, attention weaknesses, social differences, exposure, culture, education. So dyslexics, ADHD, Autistics, socio deprived (poorer backgrounds), may struggle with tums like this that assume a consistent world view - when in fact they likely have other strengths in problem solving. It’s not a one size fit all. Additionally like IQ, ability to solve these types of problem
is down to either natural ability or practise in the domain - that is you can increase your IQ by training against the core elements IQ tests look at. I tend to get candidates to take me through something they know well, or love, or have solved, and then I ask them about how they did it. This shows me genuinely how good they’ll be at the job in hand.. and is why my teams are actually diverse. |
