Psychological manipulation, even when it is aimed at nudging people in the direction of making optimal choices, is still an unacceptable infringement on personal freedom. While it may seem like a harmless nudge, it is important to recognize that manipulation is still manipulation, and it erodes the trust that people have in the institutions and organizations that are using these tactics. People have the right to make their own choices, even if those choices are not in their best interest. It is not the role of policymakers or employers to decide what is best for people, but rather to provide them with the necessary information and resources to make informed decisions. Making enrollment in a 401(k) retirement plan the default option may result in more people saving for retirement, but it also takes away their agency and autonomy. Furthermore, there is no guarantee that the choices being nudged are truly in people's best interests. The decision of what is optimal is subjective and can be influenced by personal biases and interests. Policymakers may have their own agenda in mind when designing nudges, and this could lead to unintended consequences and negative outcomes for those being nudged. In addition, using psychological manipulation to nudge people in the direction of making optimal choices can have unintended consequences for society as a whole. By taking away people's agency and autonomy, it can erode the trust that people have in institutions and organizations. This can lead to a breakdown in social cohesion and ultimately harm the functioning of society. In conclusion, while nudging people in the direction of making optimal choices may seem like a well-intentioned policy, it is still an infringement on personal freedom and can have unintended negative consequences. It is important to provide people with the necessary information and resources to make informed decisions and to respect their agency and autonomy.
