This is a setup, right? Where's the camera?
Seriously, I try generally not to engage in pointless arguing. I've spent enough time in my life engaging in (what I thought at the time was debate that might change someone's mind) pointless discussion that only serves to frustrate and annoy. I'm not always successful, but I try.
Sorry. I know it is controversial question, but a genuine one. I also know when I am working things out, I can say thing that make it seem like I am dismissing ideas. But I am not, I appreciate the input, truly.
My mind is looking for a systematic solution (a system of principles to apply in a situation, in my case) and I just cannot see how the ideas work. Please do not take this personally. Principles are hard to come by.
As for the first question, I dunno. I can say that I try to realize I don't know perhaps as much as I think, and to some extent, I do that by declining to give opinions on things I don't know enough about and having a willingness to consider I'm wrong, but I probably don't do as good a job as I'd like.
Simply keep your mind open and your ego in check. Always be open to learning. So, even if you do over-estimate your knowledge on something, you are willing to admit, accept and learn.
These (and others in the thread sysing the say thing) comprise general good systematic policies. I believe they are good at avoiding being on "mount stupid" (on the diagram). So an essential aspect of a good policy.
I work in an industry where it's essential. There is kind of a sweet spot. This is work, and I know personal relationships have a different optimum. Here is Amazon's relevant leadership principle(in the framework of an interview), but it is something similar everywhere, at least in tech, but probably everywhere.

To do about a mistake:
1) Admit 2) quantify 3) fix 4) learn 5) make use of learning elsewhere
Not to do about a mistake:
1) Being too hard on yourself 2) Ignoring mistakes 3) Minimizing mistakes
Generally, interview scenarios are sanitized heavily. I didn't really want to bring work principles (especially since tech is so disliked these days), but they are habitual for me since most of us actually spend more time at work than family (at least pre-pandemic).
What would be another set of policies to push ourselves out of the "valley of despair", where your confidence is low, but the things others are saying confidently are things already very well-considered by you.
Again, I am thinking of work interview situation as sanitized (ultimately cherry-picked and theoretical). In most work situations, people do disagree and commit, but in personal ones, that doesn't really happen on the heaviest of subjects (having kids, buying houses, etc.)
Disagree and Commit is leadership principle that encourages goal achievement in the company. Read this article and understand how this principle works.

Again, this ("have backbone") is what I had in mind, but more powerful and real--not corporate policy-speak.
