the way i have always understood it, is the ability to articulate information - especially ambiguous or abstract information and I am not specially referring to making educated guesses based on little to no context; no memory/recallability per se, but this can be but one facet of intelligence. recallability is imperative to aggregation and inference. Which is why i wager most mensa problems are based in abstraction and require prompt extrapolation. in data, when we collect the binary - 0s and 1s, all we have in the aggregate is data. When we ascribe value to said data, we have information, and when we ascribe value to information, we now have intelligence. until there is value in information it will remain exactly that, information. an intelligent person may use abstraction (and critical thought) to infer context thus ascribing value to information and create intelligence - understanding intelligence begets knowledge and implementing knowledge begets wisdom.
