Imagine that I walked into the operating room and started doing brain surgery. I’m not a brain surgeon and have zero medical knowledge but… I read about brain surgery on the internet, so I know what I’m doing. I am pretty sure that they’d stop me. That’s not “cancelling” me.
There are opinions that are up for debate and there are opinions that are poorly informed or just wrong. The know it all makes up things and due to the level of confidence they exude, others believe them, even if there is no accuracy. On the streets, they call that person a “con man.”
A “know it all” does not want to be held accountable or to prove anything because they cannot. When they feel caught, they pretend they are the victim and that having to prove what they say is unfair to ask. Their ego gets in the way of a good relationship.
Peer reviewed articles tend to reduce the poorly informed decisions from making it, that is why people look at the source of the information and whether it has been tested versus “just someone’s opinion.”
Let’s face it, you can beat any system set up. Having said that, there are some that are more challenging to beat.
Or we could keep it simple. If you do not know what you are talking about, label it opinion and be open to influence from someone who has more experience or knowledge about it. If you are “Right,” then your idea will stand up to scrutiny and you have nothing to lose.
