My contention is that I make a good faith effort to be open to the idea that others know or have experienced things or might have some thoughts that I haven’t considered adequately. And that I think this concept would be helpful to others here. That’s all, no more, no less.
It isn’t that I’m perfect, or infallible, or even immune to frustration and the occasional bout of snark. It doesn’t mean that I’m a “better” person. It also doesn’t mean that I have to accept every viewpoint as true or equally likely. Nor does it mean that I can’t criticize. Nor that I can’t take a side on a considered opinion. It doesn’t mean that this always leads to perfect results or that I’m always successful. It doesn’t mean that it’s a perfect heuristic. It’s only one more tool in a toolbox.
I think it is undervalued - and sometimes angrily pushed back against - in this community, maybe because it gets dismissed as “feelings” (and not “reason”). The reason I think this is that I've encountered here the “experienced expert with healthy self doubt versus passionate amateur with little self awareness” dynamic in action over and over again.
There’s an ongoing, half century current in the field trying to examine whether reasoning may often involve a heuristic-based, adaptive process based on incomplete and imperfect information, and less so something resembling a pure application of formal logic.
In this universe, cognitive biases extend more clearly to things like which facts you consider as possible at all in the first place and by which methods you weight them as more or less likely or influential, as opposed to merely fallacies of formal logic that we’re most often exposed to. So, the thinking goes, it can help to try to fill some gaps in this area by trying to increase the breadth of what you’re exposing yourself to and allowing yourself to take into account.
In my experience this can be a frustrating and exhausting concept to contend with as a person. You certainly can tu quoque yourself - or me, like you and others in this thread have - into oblivion. After all, what business do I have talking about cognitive biases if I've been shown to be subject the very same, and am not an expert in it? I don't know where the line is but I'm not certain it makes the concept less helpful outright. At the very least I don't think I'm claiming something that'd be considered very controversial as far as I'm aware.
