My discourse is like this:
However, sometimes knowledge could be abused. People should be aware because there are ____ who make up facts in order to look smart instead of admitting their ignorances.
It'd be awkward if I repeat "people", that's why I need a word to define this type of people.
I've found such words like sophists and pathological liars. But they aren't suitable here.
These people don't make up facts for an argument but they just want to look smart and convincing. They also give fake statistics such as "90% of people are...", "20% of our blood is..".
