There isn't a single hormone that directly increases fairness. Fairness is a complex social construct influenced by factors like personal values, cultural norms, and individual experiences. However, research suggests that certain hormones, like oxytocin, can play a role in promoting prosocial behavior and increasing trust, which are essential components of fairness.
- Oxytocin is a hormone associated with bonding, trust, and empathy. Studies have shown that oxytocin administration can increase altruistic behavior and promote cooperation, which can be interpreted as a form of fairness. For example, a study published in Proceedings of the National Academy of Sciences found that oxytocin increased risk aversion, altruism, trust, and trustworthiness, and decreased reciprocal fairness.

It's important to note that fairness is a multifaceted concept, and hormones are just one piece of the puzzle. Other factors, like social context, individual personality, and cognitive processes, also play significant roles in determining an individual's perception and understanding of fairness.
