Objective reality is complex and hard to explain or list all the facts in a single argument session. People are also good at cherry picking the facts they agree with and disregarding other related facts. As others wrote, there are also bunch of trade offs, not many subjects have clear and low amount of facts that everyone can agree upon. People tend to argue most about society rather than theoretical math or physics. Like you can argue about what is the perfect form of government but you also have to account for the people who are part of the governing and being governed, they are not ideal actors, so the practical reality isn't straightforward.

Coming back, what is objective reality, anyway? Each person perceives the reality differently. And if you go down to measure single basic part of the reality you will find out the act of measurement already changes the outcome. Or we can agree about the final, ideal state but not how to get there.

> Are you arguing against the existence of an objective reality?

I’d argue against absolute certainty in any knowledge. That isn’t a statement about reality, just our measure of it.

> There are countless facts, indisputably so.

True, but isn’t the problem here that even though there are many facts, no one of us knows most of those facts with absolute certainty, and we learned them from other people, therefore we primarily hold opinions about facts as opposed to know them first hand.

My experience of gravity correlates with the explanation I was given in physics class, but I haven’t myself proven anything about it, and I just trust other people’s stories when they tell me gravity affects light or time.

I think about this often when contemplating arguments; there’s almost nothing I personally know first hand. Like you I believe in facts, but I recognize that I’m not the source of most facts, and I’m relaying a story someone else told me. I’m guessing this is one of the reasons facts can be so easily argued, because there are gaps between facts being established and facts being told and shared. Like, it’s pretty common for scientific research results to be oversimplified and told & shared in a way that doesn’t capture the entire truth, right?

There people that gravity doesn’t exist and it’s some kind of buoyancy. Death as the final end of existence? There are many religions that claim that isn’t true. Nowadays it’s even harder who wrote what but next week if I don’t find that text again, can I be sure it was written or could be just in a dream?
