edit: seems like some people interpret “full of” as a mathematical majority which, while it may or might not be true instance to instance, isn’t my intent in posting
feel free to swap in “has a lot of” if that’s more familiar language to you :)
Critical thinking skills are essential for that, and they stopped teaching that a long time ago. It's not enough to have access to information, you have to have the skills to judge and interpret it. This is why misinformation is such a problem, people literally don't have the skills to distinguish between it and actual facts
