Self-regulated people are able to create an environment of trust and fairness, where political behavior and infighting are sharply reduced and productivity tends to be high

The answer to this statement whether if it is true or false is that, it is false. It is because self-regulated people can create an environment that produces trust and fairness but because self-regulated people tend to be more controlling to their behavior and emotions, it does not necessarily that they can only produce fairness. While political behavior can be reduced based on some instances but it does not necessarily impact of the behavior and infighting to be reduced within the instance though productivity is high.
