Summary

Are individual differences in trust subject to genetic influences? If possibly heritable, which specific gene is associated with trust? This chapter reviews previous studies to answer these questions and introduces the genetic basis of trust, including trust behavior and trust attitude. In twin studies, trust was demonstrated to be influenced by genes to some degree (about 10%–20% in trust behavior and above 30% in trust attitude). To determine which specific gene is associated with trust, researchers used molecular biological techniques to determine the genetic polymorphisms of specific genes and examine the relationship between trust and genes. Thus far, it has been found that the oxytocin receptor gene, arginine vasopressin receptor 1A gene, dopamine D4 receptor gene, and serotonin transporter gene are associated with trust level. In this chapter, we will introduce these genes and the relationship between trust and genes.
