Get out of your bubble by seeking out the truth.
I do not live in a bubble. Do you know how? I have a secret.
There are news sources and rebel academics that actually talk about factual reality. I know, I know, crazy. The world isn’t just opinion. And yes, there is bias in everything, but investigative journalism still exists. There are still some intellectuals independent from the capitalistic system. Science is a real thing, and in many ways (though limited) the world is observable and knowable. This includes the social sciences.
I don’t need my social group to reaffirm my reality. Facebook and Twitter are nice for camaraderie, but even though I surround myself with people I agree with and like, the confirmation bubble is always popped because I still have a mainline to the real world.
I have opinions, and they form and they change because I keep encountering facts. I seek out scientists, artists, academics, activists, and journalists with integrity. We don’t need to seek out biased, opposite opinions to balance out our own; we need to keep searching for and paying attention to the truth.
