I do not believe there is a way to rid discourse of bullshit on a societal level. When people speak or write, they share their individual truths, however uninformed that notion might be. There is no such thing as a collective truth, as even things with concrete evidence are discredited by some; this devaluing of facts is the root of the concept of bullshit. However, it can be very difficult to change someone’s mind to share your mindset and your truth. To combat bullshit, we need to focus on a personal level. You can only try to negate bullshit in yourself by questioning your truths to see if they are corroborated by facts. This is an interpersonal task, not something you can force on someone else. Now how we can get people to examine their own ideas is the hard part. This action is something that you need to buy into, it will not be very effective if it is forced upon people. But, if everyone bought into the same truth and thus it became capital T Truth, there would be no need for debate. I think bullshit is necessary for public discourse as it leads to better discussions and potential for change.
Does bullshit harm society? Is it inherently bad? I think bullshit plays an important role in public discourse, especially with our current president. All the talks of fake news show how the population is uninformed, it is hard to tell what is the truth and what is not. I think this also discredits media as it is easy to write something off as fake news. I also think bullshit can be completely harmless and comical. In a lot of interactions with my friends, bullshit plays a part but mostly just for comedic effect.
