Ignoring Conspiracy Theories

Ignoring Conspiracy Theories

Knowledge deals with facts. In order to have or to gain knowledge, you need to understand, gain experience in, or directly learn accurate information. You cannot have knowledge of things that are not true. Therefore, beyond knowing that a conspiracy theory is factually inaccurate or understanding its origins, you cannot have knowledge of a conspiracy theory. Importantly, what this means for us is that we can ignore implausible conspiracy theories.
In his book Vices of the Mind Quassim Cassam asks whether it is closed-minded to ignore conspiracy theories and whether ignoring them is an epistemic vice. However, Cassam explains that epistemic vices inhibit knowledge since knowledge only deals with truth and facts. Conspiracy theories such as moon landing hoax theories do not deal with facts, so ignoring them does not hinder knowledge.
Cassam brings up conspiracy theories when discussing closed-mindedness and addressing an argument that people occasionally make in favor of closed-mindedness. The argument is that closed-minded people won’t be swayed by implausible conspiracy theories, and therefore some dose of closed-mindedness rather than universal open-mindedness is a good thing. Regarding this opinion, and diving into the heart of conspiracy theories, Cassam writes the following:
“If I listen to them long enough I might change my mind and lose the knowledge that I already have. I should do everything possible to avoid or ignore [conspiracy theories], and that looks like a way of saying that the way to protect my knowledge is to be closed-minded. However, the real reason I am entitled not to listen to the conspiracy theorists is not that their views are inconsistent with my prior conception but that they are unlikely to be correct given the available evidence. Only the evidence can justify a policy of non-engagement.”
I previously wrote about analysis-paralysis and when it is ok to stop investigating something and to make a decision. At a certain point we have to judge that we have sufficient knowledge and understanding to move forward with our lives. We cannot spend time investigating every possibility, because we will run out of time and never make a decision for what to wear, who to vote for, and what to eat for dinner. Fortunately, as Cassam shows, our decision-making can and should be limited by fact and plausibility given the available evidence. Possibilities that fall far outside what is likely to be plausible can be ignored. We might be wrong once in a while, but systematically this approach is not going to inhibit knowledge. We don’t have to investigate every possible conspiracy theory. We can ignore choices, opinions, and different possibilities when they don’t match the evidence and fall outside plausible ranges. This helps reduce our cognitive load, give us an actionable way to move forward, and establishes a baseline of accuracy from which any decision, idea, or possibility must have roots. Conspiracy theories can be ignored without us being closed-minded because they don’t reach such a baseline.
