大多数公共选择的分析工作是基于相对简单的多数决策模型。这些模型被广泛使用，即使研究人员知道真实的政治环境比模型所暗示的要复杂得多。使用这种简单的模型可以有多种原因：首先，简单的模型可以让知识更经济地从一个人传递到另一个人，而不是更复杂的模型。其次，简单的模型为我们提供了分析引擎，允许我们对更复杂的现象提出各种假设，如果没有模型提供的参考框架，其中许多假设是不可能的（或令人感兴趣的）。第三，简单的模型可能是理解世界主要特征的全部必要条件。世界可能并不像它看起来那么复杂;在这种情况下，从观察到的事物中提取本质的简单模型将很好地为我们服务。
Most analytical work in public choice is based upon relatively simple models of majority decision making. These models are widely used even though the researchers know that real political settings are more complex than the models seem to imply. The use of such simple models can be defended for a variety of reasons: First, simple models allow knowledge to be transmitted more economically from one person to another than possible with more complex models. Second, simple models provide us with engines of analysis that allow a variety of hypotheses about more complex phenomena to be developed, many of which would be impossible (or uninteresting) without the frame of reference provided by models. Third, it is possible that simple models are all that is necessary to understand the main features of the world. The world may be less complex that it appears; in which case simple models that extract the essential from the observed will serve us well.
