is a good clarification. A person is able to look something up, read a paragraph which may or may not have been edited, or read an excerpt, or a quote, and as stated in the question think themself an expert on any given topic. Too often emotion, or sometimes a lack of, adds to the chaotic and confused thinking.

Seems that way.

Nobody knows more about ...
June 2015: “There’s nobody bigger or better at the military than I am.”
July 2016: "So a general gets on, sent obviously by Obama, and he said, 'Mr. Trump doesn't understand. He knows nothing about defense.' I know more about offense and defense than they will ever understand, believe me. Believe me. Than they will ever understand. Than they will ever understand."
Nov 2015: "I know more about ISIS than the generals do."
Nov 2015: "I know more about courts than any human being on Earth."
Mar 2016: "Nobody knows more about trade than me."
Apr 2016: "I know more about renewables than any human being on Earth."
May 2016: "I think nobody knows more about taxes than I do, maybe in the history of the world. Nobody knows more about taxes."
July 2016: "[L]ook, as a builder, nobody in the history of this country has ever known so much about infrastructure as Donald Trump."
Feb 8 2017: "I understand things. I comprehend very well. Ok? Better than, I think, almost anybody"
Dec 2018: "Technology — nobody knows more about technology than me."
Jan 2019: "I know more about drones than anybody. I know about every form of safety that you can have."

Want video evidence Trump said these things?

I think everyone believes that they are an expert in their particular field and we shouldnt question them about what they think and say!

Well I know I am… 🤔

No, I've never heard anyone claim to be an expert on everything, only about certain subjects. Well, other than Trump that is. He's just the best in every way if you can believe him.

Some people

Most definitely.

We are all Google experts now

No i only think that when I'm high

I'm not going to blame that one on the internet. The internet might make it a little easier to belive that, but i think the tendency predates the internet by a long while.

Foolish people (me included) have always believed that they know a great deal more than they actually do. It's kind of human nature for fools like me to find comfort in such beliefs.

It hasn't helped.

Some robots I know seem to think they know a lot of stuff.

But they still do not know how to click on all the images with traffic lights. 🚦

Some people seem to think they know everything about everything.

Certainly the leftists

I just see a lot of people claiming expertise who are totally unqualified. They are loud, emphatic, and wrong.

Add IA to that and you got it. No need for real experts any more, because it's known

People have been this way since the dawn of time. The Internet and social media has merely made it more visible.

Just the leftist... read the other replies to see what I mean...lol...

"To know all things is not permitted" ~ Horace

Well all most anything u want to know u can get it off of the Internet

Not think. They know.

People were already like that before the internet

🤔 The efficacy of the delivery system that we now call Our Own is unparalleled by actual intellect.

No. It's causing wars!

That and the dumbling down in education.
