Assuming that the person with that belief set thinks they are right, they would have to get to a point where they would own a new belief set. I’ve seen this happen through an experience (experience is a way better transformation catalyst than rhetoric) where witnessing something offers an opportunity to now see the world differently. Changing that person would be offering the opportunity to experience that thing (whatever it happens to be). Either way, the person has to own the change…you can’t do it for them.

I think the best way to process this question would be to ask yourself, “Have you changed your convictions about something?” If so, what happened where you changed your belief set?

For me, it has always been through having opportunities to see more of the world up close.

If you are in a position of authority towards a person, there is also an element of leadership where you speak of them in a way that affirms their positive qualities of whatever the belief set is and invites them to own that perspective to a point where it forces them to acknowledge the failures of their belief set in lining up with those positive qualities. For example, so and so is passionate about heritage and freedom and they always make sure someone’s heritage and freedom are honored. A racist tends to only honor their heritage and freedom, but claiming this about them would challenge them to offer what they assume for themselves towards other people.

It is a loaded question that I am not unpacking fully, but that would be my thoughts on the idea.
