Official Solution:
Traditional economic theory has long rested on the assumption of rational decision-making: that individuals, given complete information and consistent preferences, choose options that maximize their utility. Yet research in behavioral economics, notably advanced by psychologists Daniel Kahneman and Amos Tversky, revealed that individuals systematically deviate from rationality through cognitive biases such as overconfidence, loss aversion, and framing effects. The latter refers to the tendency for different presentations of the same information, such as describing a medical treatment in terms of survival rates rather than mortality rates to produce markedly different choices. These insights challenged the descriptive validity of the “rational actor” model that underpinned much of neoclassical economics.
Building on this work, economist Richard Thaler and legal scholar Cass Sunstein introduced the concept of a nudge- a subtle alteration in the context in which choices are presented, designed to steer individuals toward better decisions without restricting their freedom of choice. Examples include setting healthier food as the default option in cafeterias or automatically enrolling employees in retirement savings plans unless they opt out. Such interventions, sometimes called libertarian paternalism, aim to improve welfare while preserving autonomy.
Critics, however, argue that nudges risk paternalistic overreach and may underestimate individuals’ capacity for self-correction. Others question their long-term effectiveness, suggesting that behavioral interventions may lose potency once individuals recognize the underlying manipulation. Nonetheless, the “nudge” approach has profoundly influenced public policy, signaling a shift from viewing humans as perfectly rational agents to understanding them as predictably imperfect decision-makers operating within structured environments.
Which of the following situations would most clearly reflect a concern similar to those expressed by critics of the 'nudge' approach described in the passage?A. Students respond positively to default online class reminders and continue to attend regularly even after realizing the notifications are automated.
B. A city mandates that all fast food restaurants show healthy food options at eye level on screens in store but fail to take into account online app orders.
C. Drivers slow down in response to digital speed-limit signs that flash warnings, even after learning how the sensors work, and the behavior remains stable for years.
D. Consumers who once overspent begin budgeting responsibly after several months, without needing external prompts or reminders.
E. Employees take part in monthly fitness challenges at a company in exchange for rewards but later participation slows when they realize that the company wants to lower insurance costs.
A) Incorrect. In this scenario students keep attending class even after realizing the emails are designed to boost attendance. That means the nudge (default reminders) continues to be effective despite the audience’s awareness. Critics of nudges claim the opposite: once people detect the attempt to steer their choices, the intervention should lose force because they resent or ignore the manipulation. Since the desired behavior persists, this example does not illustrate the critics’ concern.
B) Incorrect. Here the policy flaw is narrowly practical. Healthy items placed at eye level work for in-store customers, yet the rule misses online app orders. The shortcoming is incomplete reach, not diminished impact caused by recognition of hidden influence. Critics focus on the potential for nudges to backfire when people notice and resist the steering, so this option addresses a different weakness.
C) Incorrect. Drivers slow down for flashing speed signs and keep doing so for years, even after understanding how the sensors operate. The passage’s critics worry that once individuals grasp a nudge’s purpose, they will adjust their behavior or tune it out, reducing the intervention’s potency. Because the drivers remain compliant, the situation contradicts that fear rather than confirming it.
D) Incorrect. Consumers who used to overspend now budget responsibly without prompts. Their improved behavior results from internal habit formation, not from rejecting or resisting an external nudge after discovering its intent. The critics’ argument centers on nudges losing effectiveness through exposure, not on people surpassing the need for prompts, so this case does not capture their concern.
E) Correct Answer. Employees initially join monthly fitness challenges for rewards, but participation declines once they realize the true motive is to lower company insurance costs. When the hidden agenda becomes clear, the nudge’s influence fades. This reflects critics’ worry that behavioral interventions will lose strength once individuals recognise the manipulation, demonstrating the precise failure mode they highlight.
