Back in late 1999, two psychologists from Cornell University—Justin Kruger and David Dunning—put it to the test whether people who lack the skills or abilities for something are also more prone to lack awareness of that lacking. They started off their research paper with an example of a Pittsburgh bank robber, McArthur Wheeler. McArthur was arrested in 1995 shortly after robbing two banks in the middle of the day, with no mask on, or any other kind of disguise. When the police caught up to him and showed him the footage from security cameras, the robber was confused. "But I wore the juice," he protested. As it later turned out, the poor man believed that if you rub your face with lemon juice, it will be invisible to security cameras. Yeah, right... The two psychologists did other tests too that proved that their theory stands correct—the less competent you are, the more you think highly of your intelligence.

What later has become known as the Dunning-Kruger effect could probably explain why some incompetent people are just so damn annoying. Also, it can provide an insight into why we enjoy spending time with those who are able to laugh at themselves and their dumb brain farts. Don't you think it takes a smart person to admit that they can be very, extremely, overwhelmingly dumb? Therefore, all of these 60 people, who were brave (and smart!) enough to publicly admit the dumbest things they did, deserve a medal. While we won't actually send a medal to each one of these people, we suggest you take a scroll through this list where they are sharing instances that made them question their own intelligence. As always, vote for the ones you like the most and don't forget to share dumb moments that made you question your own mind!

Things-That-Made-People-Question-Their-Intelligence A couple of weeks ago, I heard my neighbors cat meowing, so I responded with a "meow" of my own. This went on for about 3-4 exchanges until I opened the door and found it was not a cat, it was just another dude meowing back at me. So many unanswered questions.

Things-That-Made-People-Question-Their-Intelligence I have a key fob for my car. It’s set up so that if you hit the lock button once, it locks the car. If you hit the same lock button again, it locks it again and honks the horn so you know you’ve locked it for sure. The thing is, I always want to make super sure that it’s locked, but sometimes I come home to my condo super late, and my parking spot is right under someone else’s window. I noticed that if the key fob was farther away from the car when I hit the button twice, the honk was not as loud. So out of consideration, I would always wait til I was halfway up the stairs to do the double lock honk. What a great neighbor I am!

Anyway, after maybe 2+ years of doing this, one time my girlfriend and I were in my condo and I realized I needed something out of my car. So I go down there but when I get there I realize I had forgotten my keys. Well, I had my phone, so I called my girlfriend and asked if she would stick her arm out the window with the key fob and unlock my car. She mistakenly hit the lock button twice and my car honked. Really loudly! Even though she was all the way up on the third floor!

It was only then I realized...the honk was always the same. It only sounded softer when I was farther away...because I was farther away.

I have a master’s degree...

Things-That-Made-People-Question-Their-Intelligence I once had a brain fart and forgot that porcupines were animals. I was hanging out with my family and my niece mentioned that her favorite animal was a porcupine, and I laughed for a good long time before explaining to her that porcupines weren't animals. I'd gotten them mixed up with pine cones.

That's ok my first fight with my now ex husband was because we were talking about a mongoose. I said I loved them because they reminded me of ferrets which I also love. He said "How does a bird remind you of a ferret?" I asked him to think about that for a minute as I died laughing. He was so mad, he said "I had the bike, it's a bird" I said I did NOT have the bike and it is NOT a bird, just because "goose" is in the name doesn't make it a bird. lmao. I had to google that s**t to a 30+ yo man.

Things-That-Made-People-Question-Their-Intelligence I snuck out to do teenagerly things at around midnight and got back at around 4 in the morning. I very slowly, agonizingly slowly, took my keys out of my pocket, selected the correct key, inserted it into the front door lock at a speed of one tumbler per fortnight, rotated it counterclockwise while palming the rest of the keys so as to not let them jingle and successfully unlocked the door. I removed the key from the lock at the same snails pace and put my keys back in my right front pocket. I went to reach for the doorknob and rang the doorbell. That was when I died.

Things-That-Made-People-Question-Their-Intelligence A couple months ago, my husband and I went on a walk. There are a lot of trails where we live and a couple of lakes. So we walked down a trail to the lake, turned left up another trail, and ended up at the top of a street. We start walking down the street and I realize there is a house that has a wishing well in their front yard like we do. I point it out to my husband and then I realize they have the same truck we do, too. I point out the truck and then I realize that we were in front of our own house. It wasn't my brightest moment.

Things-That-Made-People-Question-Their-Intelligence One time I microwaved a single mozzarella stick for 30 seconds. It seemed an appropriate amount of time. When it was done I popped it in my mouth to eat it. It was molton lava hot. As it seared the inner workings of my mandible my brain began screaming "get rid of it!" So I did. By swallowing it. I felt the burn travel down my esophagus and into my stomach. It hurt so bad. It was only made worse by my friend laughing hysterically at me and exclaiming that even dumb dumbs know to spit it out.

Things-That-Made-People-Question-Their-Intelligence While helping my girlfriend make dinner one night we needed some lemon juice and she asked me to squeeze a lemon. Now logic would dictate you cut the lemon in half before you squeeze the juice out of it, but not this brilliant [guy]. No sir! I just squeezed the [hell] out of it, rolling and palming it in my hand until the peel finally broke, releasing the lemon juice into a bowl as requested. Needless to say, when she turned and saw what I had done she was amazed (probably by my impeccable ability to follow orders). She then asked how I ever managed to live alone, and I'm pretty sure that's why I'm not allowed in the kitchen anymore.

A couple years ago I was moving out of my apartment, so I had the whole place packed up. I had a cold at the time, so I decided to take some alka-seltzer. With all my cups put away, I get the idea that I should just toss the meds in my mouth, and drink out of the sink to wash it down. Well the tabs get stuck in my throat and the water begins activating the meds. I'm sitting there alone in my kitchen, clutching my throat and foaming at the mouth into the sink. I was ashamed I was about to die in the least cool way ever. Luckily they dissolved quickly enough for me to catch my breath and not die.

First day of university I go out to explore the campus, only to find the same odd piece of litter in the corners of multiple buildings, almost seemingly strategically placed. even more oddly, it was the same exact piece of cardboard trash I kept seeing. Strange, but probably just leftovers from an event where the university handed out something stored in them. Upon seeing the 5th or so inproperly disposed of piece of cardboard, I take it upon myself to be a good citizen and properly recycle the misplaced trash. A simple enough task that even I couldn't screw up! I casually walk to the corner, kneel down, pick up the piece of trash and...

I can only imagine what people must've thought after seeing me react to the piece of trash that had somehow outsmarted me, gluing itself onto my skin. I was like a cat with a piece of tape on its paw, flailing wildly, too afraid to scream, the only sound that could be heard was cardboard flippyflaps echoing down the halls.

After the 4th or 5th good swing at the air, the cardboard remained permanently affixed to my skin and I had finally begun to realise what was happening. I, a superior intellect, a student of a well respected university, had been caught.

By a mousetrap. GG.

At my company we had the new director of HR come in to talk to a couple hundred people. He started going on and on about how we need to improve ourselves and work on our personal standards.

Then he starts asking questions of the audience as he walks around. He says,

"Does anyone know what the R word is?"

I confidently raised my hand--thinking now is the time to get some easy face time with the new executive.

Exec: "Yes, son?"

Me: "Retard"

The entire place went dead quiet and everyone turned around and looked at me.

Black lady next to me: "Oh lawwwwd...."

Exec: "How about reorganization?"

Something like that happened to me. My science teacher was talking about how babies learn words and stuff like that (he gets off topic a lot), so I sort of zoned out, but then I heard him ask, "What is your first word?" and he pointed at me. So I said, "Elmo" thinking that he meant the first word I ever said. Apparently, we were back on topic and talking about the Scientific Process. My friends teased me about it for weeks.

So this happened a couple days ago, I got home from school tired as hell so I decide to take a nap at around 5:00. Well it turns out to be really deep and when I wake up my clock says 7:50. This freaks me the [hell] out because school starts at 7:20 and I quickly get changed and sprint out to my car to drive to school. As I'm driving there is surprisingly little traffic but I don't think anything of it and I pull up to the school parking lot. It is completely empty and I'm confused as hell so I walk over to two police officers and they inform me that it is actually 8 pm not am and I realize that I probably look like the biggest dumbass around. I just yelled at myself all the way home about how dumb I am.

Was folding laundry one afternoon.

Picked up a white shirt with some faded grey letters, looked very vintage. Had a black collar. I'm looking at this shirt and see the letters are some kind of weird font/ launguage.

It looks like the Elf language from LOTR in font and German lettering, with lots of diaeresis and vaguely familiar letters.

So I'm standing there for like 5 minutes, closely studying this damn shirt trying to figure out WTF language this is, even asking my boyfriend if he knows where he got this shirt (is it a band name? gift from someones vacation overseas?) I mean I'm going crazy trying to figure it out, this familiar yet never before seen language.

Turns out it was an American Eagle shirt inside out...
