Desirable Difficulty & Productive Struggle

Robert Bjork's principle that certain effortful obstacles in learning (spacing, interleaving, retrieval, generation) slow acquisition but deepen retention and transfer — the effort is the mechanism, not a flaw — which is why AI's removal of difficulty threatens the learning it appears to assist.

Also known as: desirable difficulties, ønskelige vanskeligheter, productive struggle, generation effect, retrieval practice, spacing effect, effortful learning, the effort is the mechanism

AI coding creates two kinds of debt. You're only measuring one

Productive struggleThe 'wrestling with a problem' that Jurić identifies as the actual mechanism of learning, and which AI removes when used for generation-and-acceptance rather than generation-and-inquiry. Never defined precisely — used descriptively, not operationally.

ønskelige vanskeligheter (desirable difficulties)Robert Bjork's principle, borrowed as the article's fulcrum: the effortful resistance in learning is not a flaw to be engineered away but the very mechanism by which learning happens.
