The article discusses how various systems and policies can create discontinuities that lead to unintended consequences, such as people trying to lose money to qualify for health insurance subsidies or prosecutors charging specific amounts of cocaine to trigger mandatory minimum sentences. These discontinuities can be found in tax policy, healthcare, education, and other areas. The article argues that smooth phase-outs or gradual changes can help mitigate these issues. The examples provided illustrate how people may exploit or be affected by these discontinuities in different contexts.
