Methodological skepticism is a way of using the process of doubting in order to arrive at certainty. After learning about this i'd have to say that methodological skepticism makes sense and is a good way to approach situations. Come to think of it i often do this unknowingly, most of the times when i am told something i don't automatically believe its the truth just because someone told me. I like to find out and explore for myself whether i believe it or not. But for the most part we as a society tend to believe things until it becomes impossible to believe rather than doubting everything, i say this because its just easier that way and less controversial rather than doubting everything,but this doesn't necessarily mean that methodological skepticism isn't a good strategy, its a strategy that isn't the easy way out that's all. We believe things until we have reason to doubt. Overall in my opinion methodological skepticism is a good strategy it allows us to construct our own beliefs. for example in our legal system 'we' are suppose to be "innocent until proven guilty" but most get treated "guilty until proven innocent" in this example methodological skepticism would change the outlook in legal situations.
Descartes was a rationalist but developed methodological skepticism as a way to have more genuine knowledge and certainty rather than having doubts and not solid beliefs.
