Human vs. AI vs. Human and AI: Who Does Better Work?
There's a comfortable assumption running through most corporate AI strategy right now: a skilled person plus an AI tool will outperform either one alone. It's intuitive, it's reassuring, and it lets organizations roll out AI everywhere without asking hard questions about where, specifically, it helps. Only a subset of the eight contain all three conditions in a single design; the remainder provide controlled two-arm evidence (most often human-alone vs. human+AI, or human-alone vs.

It's intuitive, it's reassuring, and it lets organizations roll out AI everywhere without asking hard questions about where, specifically, it helps. It's also not what the evidence shows. We identified eight controlled empirical studies — through a structured literature search described below, not an arbitrary shortlist — that compare at least two of unassisted human performance, AI-alone performance, and human-plus-AI performance on a well-defined task, using real accuracy, speed, or quality measurements rather than survey sentiment.
