GP gave a hypothetical, and I'm responding to that hypothetical.
In fact, I did not refuse to consider his arguments. I considered them. They're poorly sourced, terribly reasoned, and not very well communicated. FWIW I do feel bad that they guy lost his job for what amounts to poor communication, worse argumentation skills, and a misplaced belief that engineers are special enough to be exempt from the generally shitty employee/employer relationship as it exists in the USA.
But that's all beside the point, because I'm responding to a hypothetical.
> You'll never find the truth if you irrationally dismiss arguments
My point is that you'll ALSO never find truth if you climb every adversary-constructed hill in the state space. Your suggested method for finding truth is even worse than mine, and what's more, you're claiming the opposite.
I'm at least admitting that I have to use heuristics. You're just watching the tower of exponentials crank up and claiming "no problem! We can compute that!"
> But believing you've already arrived at the truth would be arrogant and closed-minded, right?
It's possible to remain open to new ideas and also not waste time on evaluating or responding to arguments that aren't motivated by a genuine search for truth. (Again, this comment was in response to a hypothetical.)
I highly doubt you actually disagree with me in practice, because such a life would surely doom you to misery and unemployment. Do you spend all your free time reading and/or responding to arguments from flat earthers, BS science posted on white supremacy forums, and marketing claims made by infomercials and bill boards? Do you engage with every crank preacher and evangelist who comes to your door or yells at you on the street? Of course not.
