It's funny how often, the ones with the lowest intelligence are actually the ones who think they know the most. That's because a glaring sign of sub-par brightness is a lack of curiosity or willingness to learn.
Intelligence isn't about high IQs, acing tests, or flying through trivia. It's the ability to derive information, learn from experience, adapt to the environment, understand, and correctly utilize thought and reason. That's the definition, according to the American Psychological Association.
Many of those lacking in intelligence will, quite ironically, see learning as a waste of time and it's unlikely they'll get this far down this article.
"They don’t have the intelligence to see how learning can benefit them. They stop learning when they graduate," explains the PsychMechanics site. "On the other hand, high-intelligence people accept that learning is a lifelong thing."

Curiosity makes the world go 'round, and a lack thereof keeps people with low intelligence stuck exactly where they are... with just enough knowledge to barely get by in an ever-changing world. And that's why these folk struggle to adapt if or when things suddenly shift, which they ultimately do.
"Adaptability is critical to problem-solving and survival," notes the site. "When their problem-solving methods no longer work because things have changed, people with low intelligence struggle with adapting to new circumstances. They get too comfortable with their old ways of thinking and doing things."

Example: travelling in an airplane is generally safer than in a car
"Actually that's not true, I know someone who perished in an airplane crash".
