When we accept someone's authority over us, we know instinctively they expect us to be loyal. This type of loyalty becomes coercive if we expect punishment for being disloyal. Loyalty based on fear toward someone who has power over us probably needs a different name.
Vox: The problem with Trump's idea of loyalty, explained by psychologists, 2017-Jun-8 by Julia Belluz and Brian Resnick
David DeSteno, a psychology professor as Northeastern, explained that there are a couple of methods people can use to build loyalty and trust.
One is, you meet someone, work with them, and learn about whether they’re going to have integrity and cooperate with you, DeSteno said. “Trust is a bet that a person is going to hold up his end of the bargain — accept some short-term cost for longer-term gain.”
Psychological studies show this pattern often holds in human relationships. We grant power to those who are empathetic, and those who look out for the greater good. A more Machiavellian approach works, too, but it can be off-putting. “People intuitively recoil against people who look as though they will exploit others, the social collective, and undermine the greater good,” Dacher Keltner, a UC Berkley psychologist who studies power, says. “I see Comey's actions as in part guided by this intuitive tendency.“
The other way to build trust is less effective: You demand or ask for it, as Trump does. This normally doesn’t work, except for in relationships with a power differential.
