I often read the notes and reblogs of Tumblr posts, which may sound tortuous, and sometimes is, but is also highly informative when one applies critical thinking to what is being said. It's also, I would think, not nearly as tortuous as being subjected to getting a lot of notes on one's own post on Tumblr. I think people often complain when they're told competing information and just kind of give up evaluating it. I find this unfortunate because it is rarely the case that all arguments made are equally well-constructed. And in fact having a number of arguments made by a variety of different people all in one place can be a very valuable resource. So while I do often get frustrated by trying to discern the truth for myself given the amount of incorrect information and outright lies out there, I know there are processes that can be applied to discern more correct arguments from less correct ones, and also to know which statements are irrelevant to determining correctness.
Some statements are simply about declaring a position, not proving it. These have no relevance when determining the the value of that position. People who agree with it will make positive statements of this kind about the position, and people who disagree will make negative statements of this kind about the same position. Whether one enjoys them or loathes them, this has no bearing on the truth of the statement itself, because this kind of statement is simply not designed to help uncover truth.
Instead, we must look for actual arguments being made. And we must ask questions about these arguments. For example, is the logical foundation of the arguments correct? Are sources given? Do the sources actually say what the material says they say? What are the limitations and biases of the sources?
If you ever evaluate a source to have absolutely no bias, this is incorrect, because all sources are biased. Some biases are stronger or more relevant than others, but everyone has their own biases. This is in fact the point of people, that even when we are not predictable, we are directed and not simply randomly or aimlessly adopting positions. Unlike dice, which we want to be random, humans do not benefit from random behavior. We also are unable to make decisions based on a perfect and complete understanding of the world around us. Thus we develop biases to help us to navigate that world. This helps us survive, but it also means we are biased towards making certain types of errors. By understanding the biases involved in a situation, you can understand what conclusions the biases may predispose one to. Of course, just because someone has reached a conclusion that their own biases support doesn't mean they're wrong, just that this should be one factor used to evaluate the quality of the argument.
When references are given, it is important to check whether the references actually support what the argument is using them to support. Sometimes people misunderstand a reference or purposely misrepresent it. Either way, the end result is a reference that does not actually support the argument being made. Depending on the references given, this may require advanced reading comprehension and deductive skills, as well as a great deal of time to accomplish. That's just the nature of things! No one can do this all the time. But it should be done regularly if one cares about truth.
Examining the logic of an argument is also a vital part of determining its value. Evidence by itself is meaningless without the mental tools to reason about its wider ramifications. Again, a very time consuming process, but a necessary one.
Going back to my mention of Tumblr notes and reblogs of posts, I find them useful to read because they're often an organic compilation of opposing viewpoints (along with a great deal of completely irrelevant chatter). And by taking the time to assess the arguments given in the ways I've mentioned here, I often feel that they provide valuable additional understanding of the assertions in the original post. And that's why I like to read notes and reblogs on posts.
