Delhey and Kohler assume that the happiness distribution at the population level is essentially normal, but that this is distorted by the fact that happiness is measured in samples using scales that are discrete and two-sided bounded. This assumption is tested using the probit method and rejected.
德尔海和科勒假设，人口层面的幸福感分布本质上是正态分布，但幸福感是通过使用离散的双边有界量表在样本中进行测量，这一事实扭曲了幸福感分布。这一假设使用概率单位法进行了检验，并被拒绝。
