Common sense is free of charge. You don’t need to spend a single cent on making practical judgments, nor do you need to acquire them using special knowledge.

Yet, some people would still choose to go through life using zero basic logic, seemingly uncaring whether they put themselves or others in a compromising position. These photos are examples of that, most of which may leave you shaking your head in disappointment while letting out a chuckle or two.

Scroll through and enjoy some laughs of your own.

For context, here when the tide is low there is a small road and a place to park, but when the tide gets high the road fully disappears. This happens at least 10 times a year; you would think that people would be cautious, bearing in mind that there are literally 30 signs, like the one in the image, stating that the whole thing floods. Some people just lack common sense, I guess.

Some experts may disagree with the notion of “common sense.” One typical argument is that it isn’t universal, where one’s environment growing up differs from another, and therefore, shapes varying forms of logic.

“Why do so many people misspell ‘lose’ as ‘loose’? Why do so many people say ‘literally’ when they mean ‘figuratively’? ‘Common’ isn’t a good enough criterion to make something true,” author and researcher Dr. Christopher Dwyer wrote in an article for Psychology Today.

However, as you will notice while scrolling through, the context in this case revolves around common sense regarding the basic definitions of courtesy. We all frown upon actions that may cause friction with another person, whether it be showing disrespect or acting in a way that could put people in potential danger.

A study by the University of Oxford found that people generally tend to favor someone who adheres to common-sense morality. Specifically, findings revealed that a person who refuses to eliminate a single individual to save the lives of many others is considered more trustworthy compared to someone who would go the opposite route.

According to Cornell University professor David Pizarro, one of the experts who worked on the study, “(It’s) not because they are sticklers for the letter of the law, but because the rules themselves tend to emphasize the absolute importance of respecting the wishes and desires of others.”

#12 No Common Sense

London-based psychologist Dr. Jane McCartney shared her definition of common sense. As she stated in an interview with The Independent, it’s “the ability to imagine the consequences of something you do.”

Given that definition, evolutionary psychologist Bruce Charlston concluded in a study that people with higher IQ tend to struggle more with common sense because they “over-use general intelligence in problem-solving” and subsequently “override instinctive and spontaneous forms of evolved behavior” often associated with basic logic.

“When it comes to solving social problems, the most intelligent people are more likely than those of average intelligence to have novel but silly ideas, and therefore to believe and behave maladaptively,” Charleston said in his study.

This person’s headlights, with the power of a thousand suns, caused a ring to form around my car, so I could not see anything. The road curves a little bit, but because I was driving blind, I almost hit the car to my right. But I’m so glad this person feels so safe being able to see so far ahead and clearly at the expense of my safety. How is this legal?

#40 Went To See The Deftones Last Night

Got seats in the nosebleed section, and this guy is the only one in my entire section standing up. The glow around him is the stage. I was tempted so many times to tell him to sit down, but I’m not sure what the “rule” is on this. I guess he’s “allowed” to stand up, but I feel like this is just common sense. It’s different if everyone is standing, but he is the only one standing.

Halfway through the show he turns around and says, “You guys don’t mind if I’m standing, do you?” I reply with, “I can’t see, but you do you.” He kind of froze for a few seconds and said, “OK, boss,” and sat down. He stayed seated until they played Change, and that’s when everyone, including the nosebleed sections, stood up, and of course I’m fine with that.

#41 My View For The Entire Doja Cat Concert

This 6+ foot tall dude (probably 6’4-5) was standing for almost the entire concert. I’m all for dancing and having fun at a concert, but have some common sense; if everyone is sitting down and you’re that tall, read the room. When he was sitting down, he leaned back, and his head was almost resting on my knee.

Knowing that someone who has the lack of brainpower to even act this way won’t likely be open to polite conversation, I don’t take it upon myself to ask them not to. So I had asked my flight attendant for help, and he said that there was nothing they could do—so clearly they don’t even know that stipulations exist within the contract for the carrier, and it would’ve likely empowered them as well because they expressed frustration at how often they see this kind of thing and more. I travel enough to get frustrated by this kind of thing. I can’t imagine how they feel on an almost daily basis. They did tell me things have gotten much worse with how people behave.

Not only did my seatmate keep his disgusting feet on the bulkhead wall almost our entire trip from Chicago to Sacramento, but he also got up twice to use the bathroom while barefoot.
