The arrival fallacy, akin to the 'happily ever after' fallacy, reveals our flawed expectations about future happiness. People often believe that achieving specific milestones, such as buying a new house or receiving a promotion, will lead to significant and lasting joy. However, research in affective forecasting shows that these predictions are typically inaccurate; the actual boost in happiness is less intense and shorter-lived than anticipated. This misconception persists even among wealthy individuals, who may chase higher financial goals—thinking extreme wealth will bring lasting happiness—only to find that it doesn't meet their expectations. Instead of reevaluating their assumptions about fulfillment, they often set new, higher targets, continuing the cycle of disappointment without recognizing the fallacy in their rationalizations. This pattern underscores a common human bias regarding the relationship between life circumstances and emotional well-being.
