From Decision Theory to Personality Based Decision Theory

在这项研究中，pi计划开发一种新的人类经济和战略决策和行为理论，对其进行实验验证，并研究模型中确定的因素的神经和遗传基础。这种方法包括统一两种不同的人类行为理论观点。一种观点来自人格理论，涉及所谓的“大五”——影响行为的人格的五个主要方面。第二种观点来自决策理论，认为经济行为是由对不确定性的态度和对奖励和惩罚的分配的态度决定的。将这两种理论结合起来，就产生了一个包含七个或更多参数的特别的人性模型。初步数据显示，这大大提高了我们预测行为的能力。研究将进一步探索该模型的预测能力，并将人格和决策理论衍生的特征与它们的神经和遗传基础联系起来。就更广泛的影响而言，这项研究将有助于我们在特定环境下预测个人行为的能力，以及在需要的情况下调整干预措施以改变行为。

In this research, the PIs plan to develop a new theory of human economic and strategic decision making and behavior, to test it experimentally, and to investigate the neural and genetic basis of the factors identified in the model. The approach involves unifying two different theoretical views of human behavior. One view, derived from Personality Theory, involves what are known as the "big five" -- five major dimensions of personality shown to influence behavior. The second view, derived from Decision Theory, is that economic behavior is determined by attitudes toward uncertainty and attitudes regarding allocations of rewards and penalties over time. Aggregating the two theories produces an ad hoc model of human nature with seven parameters or more. Preliminary data show that this increases our ability to predict behavior substantially. The research will further explore the predictive power of the model and relate the traits derived from personality and decision theory to their neural and genetic underpinnings. In terms of broader impacts, this research will contribute to both our ability to predict individual behaviors in given contexts and tailor interventions to modify behaviors in circumstances were this is desirable.
