Last thought, when others disagree with me - I do spend a bit more time on the subject to double check my thinking and to assess their opinion in greater detail

Last thought, when others disagree with me - I do spend a bit more time on the subject to double check my thinking and to assess their opinion in greater detail. Finding places where oneself was incorrect is a good way to grow. Unfortunately, chat communities on the modern internet are more about performative trolling (as you would put it), rather than ever admitting mistake or being wrong. It's about noise generation and not much more. With luck, hacker news can be a last bastion where the noise is unwelcome, whereas facts, data and analsyis are welcome. That is a difference between reddit or Twitter & here.
