One can't necessarily conclude from what people did answer correctly on a test what they could answer correctly. Were they trying their best? Why would they? It's boring and they weren't presented with any powerful reason to really care a lot about doing their best.
There is a further issue of how long it would take people to learn these skills, if they genuinely wanted to, and got helpful explanations. If someone doesn't know a skill, but could learn it in 30min if he ever wanted to, then that's no reason to call him dumb. I think to judge people you have to look at how well they learn rather than what they currently know.
