Thinking clearly/ rationally

Humans have never had so many ways to augment their thinking. But do we have a clue how to use them?
Write a thesis-driven paper in which you identify and explain in detail some of things that make it more difficult or easier to think clearly and rationally.
On this essay, it should be easy to identify your subtopics. The difficulty will be in explaining how and why something makes thinking difficult. If you say “internet propaganda” makes it hard to think clearly, you can’t just stop there; you have to go into details to explain exactly how the propaganda affects people.
