Debatir sobre un tema oralmente solo tiene sentido si has pensado mucho antes… y escribir es pensar.

Having a conversation with someone else about your ideas is only superior to writing about them under two conditions. First, if you have already thought about your ideas on the topic a lot and have carefully examined your chain of reasoning, which, as I have already explained, is best done in writing. And second, if the other person is smart, has thought about the topic a lot as well, and values truth over consensus. If, and only if, both of these conditions are met, a conversation can be more fruitful in sharpening your ideas than writing about them. There are other advantages to conversations with regards to creativity, thought-provoking impulses, and inspiration, but for thinking deeply about a topic, writing is superior to a conversation

Expresar las ideas al extremo pone más fácil la búsqueda de “la verdad”:

It is not a form of arrogance to express the most extreme consequences of your ideas; it is a form of intellectual honesty. In this way, your ideas are widely open to criticism and you are therefore more likely to learn something. You are also more likely to look stupid, but that is a price you must be willing to pay.

This way of expressing ideas can sometimes be perceived as rude because, in contrast to most other people, you are not searching for consensus but for the truth.
