TL;DR:<\/strong> The controlled evidence on AI and knowledge work looks contradictory until you sort it. A Science experiment with 453 professionals found average task time fell 40 percent. A Quarterly Journal of Economics study of 5,172 support agents found 15 percent more issues resolved per hour, with the most experienced agents gaining almost nothing in speed and losing a little quality. An Organization Science field experiment with 758 Boston Consulting Group consultants found 12.2 percent more tasks completed and 25.1 percent faster on 18 in-frontier tasks, but 19 percent lower odds of a correct answer on one task deliberately placed outside the frontier. A 2025 randomized trial of 16 experienced open-source developers working in repositories they knew for about five years found AI made them 19 percent slower, while they predicted it would make them 24 percent faster. Ordered by the user’s task-specific expertise, those five results form a clean gradient: the deeper your existing mastery of the exact task, the smaller and eventually the more negative the measured effect. A day that scales is therefore a day that is layered, with AI concentrated in the layers where expertise is shallow and deliberately restrained in the layers where it is deep.<\/p>\n Most advice about working with AI is written as if the tool has one effect size. Adopt it, get faster. The controlled evidence does not support that, and the disagreement between studies is not noise. It is the finding.<\/p>\n Four research groups have now run credible experiments on generative AI and professional work, using different populations, different tasks and different designs. Their headline numbers span a range of roughly sixty percentage points, from a 40 percent reduction in time taken to a 19 percent increase. Any framework that cannot explain that spread is not a framework. It is a preference.<\/p>\n
