This is something that salespeople understand well. I once asked a pharmaceutical rep how he persuaded doctors—who are notoriously stubborn—to adopt a new medicine.

You must also apply “the rule of seven touches.” Personally “touch” the doctors seven times, and they will come to know you; if they know you, they might trust you; and, if they trust you, they will change. That’s why he stocked doctors’ closets with free drug samples in person. Then he could poke his head around the corner and ask, “So how did your daughter Debbie’s soccer game go?” Eventually, this can become “Have you seen this study on our new drug?
