Economist Dr. Mark Chen argues that basic income pilots show promising results but cannot predict effects at national scale due to fundamentally different economic dynamics.
Which methodological observation would best support Chen's scaling concern?
Pilots are expensive
Pilots don't affect prices, labor markets, or tax burdens because they're too small; at national scale, $10 trillion annually would transform economic behavior in ways no pilot captures—a fundamental methodological limit
Some pilots show positive results
Policymakers disagree about UBI
Correct Answer: B
Choice B is the best answer. Specific mechanisms that operate at scale but not in pilots proves the prediction problem.
đź’ˇ Strategy: Scaling concerns need identification of dynamics that only emerge at scale.
