Dogmatism may or may not rest on the existence of a monolithic coherent dogma. If each participant believes that their anecdotal viewpoint reflects an overarching distributed "reality," then it may or may not be fruitful to consider some set of those viewpoints as a consolidated ism.
It may also have to do with the prevalence of confirmation bias and bubblicious echo chambers.
A quasi-plurality of the ones who bothered to vote this time around have chosen, for whatever reasons, a conscience-free BS artist who resembles the love child of President Dwayne Elizondo Mountain Dew Herbert Camacho and Berzelius Windrip. Buckle up, buckaroos!
Nice! ... heh.
This is why I preach the virtue of empirical self-doubt--internalizing as best we can the practice of subordinating our own sentiments and perceptions on empirical matters to the results of sound scientific and critical thinking processes (i.e. don't believe everything you think). We can't opt out of investing emotionally in anything (besides, that would really suck), but we can
make a conscious and deliberate decision regarding in what
we invest. We know our best shot at getting it right regarding empirical matters is about the proven methods we've learned that are precisely
about curbing our inclination and talent with fooling ourselves (getting in our own way), which I think makes clear both what's wisest to invest in, and why.
We'd do well to make our emotional investment regarding empirical matters in the soundest processes of epistemology we've developed--science and proper skepticism/sound critical thinking--because we've learned through these methods that confirmation bias and all sorts of specific perceptual errors and other vagaries are simply functions of the human brain's standard operation. If we care about getting it right rather than falsely affirming the perhaps comforting presumption of the accuracy of our natural perceptual and stimulus processing arrays, we'd damn well better keep our brain in check. If we don't, we will
fail ... a lot more
than we'll fail if we do our best to exercise self-discipline and the intellectual humility required to prevent ourselves from falling into these many pitfalls inherent to human brain ownership.
A brilliant human mind without adequate intellectual humility is just a brilliant deceiver. Smarts are secondary to humility when it comes to functional thinking about the cosmos.
