Being unwilling to verify facts.

"The significant difference between intelligence and stupidity is that intelligence has its' limits."

(quote often wrongly attributed to Einstein)

Stupidity is job security.

In my opinion, stupidity is making the same type of cognitive errors and decisions repeatedly. Yes, I’ve heard the definition of insanity is doing the same thing over and over again while expecting a different result, but stupidity is a failure to take cognizance of one’s ignorance or shortcomings, ignore new information and thus fail to learn, whether it be from one’s own prior mistakes or the mistakes of others.

It may not exist at all. Just as there is no such thing as dark, only a lack of light, and no such thing as cold only a lack of heat, so there may be, no such thing as stupid only too little thinking.

Just last week I posted a video on Stupidity.
Interesting take.

Stupidity is flawed thinking that goes against ones own best interest.......

a universal human characteristic in which comprehension is inadequate or inaccurate resulting in errors. sometimes a result of limited cognitive potential, sometimes lazy mindedness.

Then people discover A Glitch in the Matrix and start “thinking” way too far outside the box with Mandela effects everywhere in sight. So it can go the other way.

But there are post-structuralists such as Baudrillard who inspire us to think outside the box. The Matrix was a bastardization of his ideas.
