Mechanisms of justification are what we come up with to make our facts fit the frame. In other words, when we have a concept in mind we want to keep, we will don our scientist cap to seek out and manufacture evidence to support our favored concept. We all do it unconsciously so there’s no need to feel guilty about it, it’s a survival technique. We can, however, call people out on the mechanism when it drums up weak “facts” to fit that frame.
Two standbys in current political discourse are getting tired. They are used so much that it probably doesn’t even raise a red flag when they are used. I’m sure there is a fancy logical fallacy name I could apply to it if I wanted to be fussy, but I’m going to call them like I see them – the “if it ain’t broke, don’t fix it” rule and “separate but equally bad behavior” theory.
