Wrong until proven right.   The principle of openmindedness opens many people to being gullible and falling into traps, or an increased difficulty in navigating life. It's so easy to misunderstand post-rationality, and end up wasting years under new age BS, all in the name of openmindedness. At the same time, the principle of openmindedness states that you don't know what you don't know, and so you can't be closed to it.   A simple principle that has helped me is to navigate worldviews: wrong until proven right. This needs more nuance. Wrong until proven right doesn't mean closedmindedness. It's just a compass, that will likely serve you well. By proven I don't mean scientific studies. I mean a much broader and intuitive idea of proof. Let's add the "". Wrong until "proven" right. Let's not be rigid, it's intended to be a simple framework.   So, wrong until proven right. You're still acknowledging you don't know, so you're not entirely denying another perspective, but at the same time, you will entertain it with a degree of seriousness that's grounded on something decently solid. This is intended to be a principle for everyday life, and somewhat for deep philosophy too. But it's still quite simple as a framework, and that has its pros and cons, so don't tear me apart on the edge cases.   Can you see the distinction between this and closedmindedness? Hopefully this saves you from some dead ends
