We don't equip people to do it through our education systems in America. What we're doing is sending millions of people out into the world, wholly unprepared to navigate it successfully, which leaves them vulnerable to manipulation and exploitation.
I don't personally blame Twitter. This is such a gigantic problem, that pinning it to a single source is just understating what's happening. If America wants to survive another 100 years, it will have to find a way to fix its "lack of critical thinking skills" problem in a way that flips the statistics, which is more or less impossible, without swift and decisive action to make large changes to how we educate our children.
