AI's hidden cost: the human verification tax slowing productivity gains

As companies deploy AI to automate office tasks, a new problem is emerging: the need for human workers to verify and oversee AI outputs. Surveys from Workday, Google, MIT and other organizations reveal what researchers call a "verification tax"—the labor required to check AI work before it can be trusted or used.

This oversight burden is becoming a significant bottleneck that limits the efficiency gains companies expected from AI adoption. Rather than AI simply replacing human work, it is instead creating a hybrid workflow where humans must validate AI decisions and outputs.
