AI helped consultants perform better. The knowledge did not automatically stick.

An experiment involving 487 management consultants found that AI assistance improved unfamiliar task performance without a detected advantage on subsequent unaided technical questions. The Nature Human Behaviour study is useful because it separates two ambitions that are often bundled into the word upskilling. One is doing a task with a powerful tool beside you. The other is acquiring knowledge you can use when that tool is absent. Both can matter, but success at the first does not establish success at the second. There is something genuinely encouraging here. Helping people attempt unfamiliar technical work can widen participation and make expertise more approachable. A professional does not need to recreate every calculation from memory to contribute meaningfully. Assistance is not cheating, and dependence on tools is hardly new. The caution concerns the promises organizations attach to adoption. If a training program claims to develop durable capability, it should measure that capability rather than infer it from a polished assisted output. Otherwise, employees may receive new responsibilities without the independent understanding needed to spot a changed assumption or recover from a bad answer. This experiment does not establish that AI prevents learning, causes long-term deskilling or replaces data scientists. The task setting, participant selection and timing limit those conclusions. A constructive response is to preserve the benefit while testing the learning claim: assess assisted delivery, then unaided explanation and later transfer to a different problem. That gives learners credit for what they can actually do and gives employers a more honest picture of what their training purchased.
