If you want to break this you have to know the person and ask key questions afterwards. Their distortion field is held together by beliefs and principles, not empirical analysis.
For instance, for my father, the question "how is this treating people responsibly? How can we expect the behavior of those guards to be held accountable?" would pierce this ... but really you have to know how the person doing motivated reasoning thinks.
I have half a century of talking with my father. If you think this is my first strategy as opposed to one that took years of therapy and personal struggle, I dunno what to tell you.
There's a wide body of social and psychological research on this stuff including multiple university departments (communication, psychology, sociology, management, teaching, etc) because "simply talking to people" doesn't actually work.
