Empirical truth can only go so far. I say this as an engineer. We only have so much evidence of anything. And the first thing they started teaching in my engineering classes was how to handle unknowns. Because they are what is dealt with every day.

You're right, nuance is everywhere and life is complicated. But asserting your only bias is toward truth is probably the biggest lie you tell yourself. I get it, I'm a big fan of capital T Truth as well and in certain fields, like science and (good) journalism, being perfectly unbiased is held as the gold standard (it's an impossible one). And being honest with yourself is hard. But disbelieving your own biases is a great way for them to take over your life and you'll never know.

I apologize for being harsh. Text is a blunt medium. I would just encourage you to really look at your day to day interactions and try to spot when you're being judgemental. And you'll miss most of it, that shit runs on autopilot and it takes practice to notice. And most importantly, don't think that having biases is inherently bad. It's human.
