The Easterlin Hypothesis, also known as the happiness-income paradox, suggests that there is no significant relationship between income and happiness after a certain point. Alternative terms for this concept include the income-happiness paradox, the Easterlin Paradox, and the happiness-income relationship. Scholars have also referred to the concept as the "platypus of social science" due to its elusive nature. In recent years, there has been ongoing discussion and debate around the accuracy and validity of the Easterlin Hypothesis, with some questioning whether there is truly a saturation point in the correlation between income and happiness.
