Omission and commission in judgment and decision making: Understanding and linking action‐inaction effects using the concept of normality

Research on action and inaction in judgment and decision making now spans over 35 years, with ever‐growing interest. Accumulating evidence suggests that action and inaction are perceived and evaluated differently, affecting a wide array of psychological factors from emotions to morality. These asymmetries have been shown to have real impact on choice behavior in both personal and interpersonal contexts, with implications for individuals and society. We review impactful action‐inaction related phenomena, with a summary and comparison of key findings and insights, reinterpreting these effects and mapping links between effects using norm theory's (Kahneman & Miller, 1986) concept of normality. Together, these aim to contribute towards an integrated understanding of the human psyche regarding action and inaction.
