Regressive, or backward, refers to a process or trend that moves in the opposite direction of progress or development. In various contexts, it can describe policies, behaviors, or systems that revert to less advanced or less effective states. For example, a regressive tax system places a heavier burden on lower-income individuals compared to wealthier ones, leading to increased inequality. In psychology, regressive behavior can occur when individuals revert to earlier stages of development in response to stress or trauma. This might manifest as childlike behaviors or coping mechanisms, indicating a temporary retreat from adult responsibilities and challenges.
