“He Invented Oxygen”: 50 Exact Moments People Knew They Were Dating An Idiot

It is said that prevention is better than cure. And since there is no cure for stupid, avoiding dating an idiot seems to be the logical option here. Sometimes people hide it so well that the idiotic statements take a while to slip out. But other times, the joke's on you. Because the signs were probably there, you just missed them, or chose to ignore them.

Below is a crash course on how to spot the proverbial blunt tools in the shed, which we think you might find interesting. Afterall, if you didn't like learning or reading, you probably wouldn't be here in the first place.

Which brings us to point 1. People who have low IQs aren't very curious. They show little interest in gaining new knowledge, digging a little deeper, or reading and questioning the full article behind that potentially fake headline. They feel they know enough and couldn't be bothered to look beyond the "what" to figure out the "why?"

Does your date use the same small words over and over again, when regurgitating a boring story? That's a Red Flag coming right out of their mouth.

Those on the lower end of the intelligence spectrum tend to have smaller vocabularies and lower intellectual curiosity overall, notes Your Tango. "They don't think outside of their own worldview, and have a limited ability to see other people's perspectives, which can make them fairly close-minded."

Unfortunately, people who have low IQs could also have something else known as the Dunning-Kruger effect. This annoying thing is when people who actually know very little on a certain topic assume they're very knowledgeable about it. In other words, they think they're intelligent and there's nothing you can do to change their narrow mind.

"The scope of people's ignorance is often invisible to them," wrote Psychologist David Dunning wrote. Think of the people on this list, convinced that denim comes from cows, or that oxymoron is a cleaning solution. No, moron!

People operating with an open mind, or in a higher intelligence bracket, would be more likely to recognize and admit what they don't know than people with low intelligence. They lack intellectual humility, is how Your Tango puts it, which means they don't acknowledge that they struggle to understand certain topics.

"People with low IQ lack cognitive flexibility, or the ability to be open-minded. As a result, they're hardlined in their thinking, and they don't shift their opinions very often, if ever," reads the site. "Even when presented with new information, they refuse to change their opinions."

Of course, what that means is that they don't take well to being challenged intellectually. "If say denim comes from cows, then denim comes from cows. I've done my research."

Forget about thinking outside the box when it comes to the lesser intelligent of the human race. They're likely to see things in black and white. This is something referred to as "dichotomous thinking" or "polarized thinking." And according to the American Psychological Association, it's defined by thinking in terms of polar opposites, without acknowledging that there are other possible outcomes besides the two extremes of good and bad.

"People who display dichotomous thinking have a tendency to use words like 'always,' 'never,' and 'impossible,' when describing themselves or their situation in life," notes Your Tango. "This kind of thinking can cause stress in relationships, as people see others as falling firmly on one side of the spectrum and can't recognize their inherent nuances."
