Everyday Habits That Reveal a Low IQ (Backed by Psychology)
Some people speak with complete confidence… even when their logic makes no sense. Psychology explains exactly why this happens — and how certain everyday habits quietly reveal a low IQ.



In this video on Simplify Actually, we break down the real psychology behind overconfidence, emotional impulsiveness, black-and-white thinking, lack of curiosity, and constant blaming. You’ll understand why some people stay mentally stuck, why they can’t handle disagreement, and why they never grow no matter how old they get.

Chapters:
00:00 Intro
0:38 - Overconfidence Without Real Understanding
1:26 - A Complete Lack of Curiosity
2:12 - Black & White Thinking/Cognitive Rigidity
2:50 - Poor Emotional Control (being reactive instead of being responsive)
3:30 - Blaming Others for Everything (having an external locus of control)
4:09 - An Inability to Handle Opposing Viewpoints



These insights are backed by real research — including the Dunning–Kruger Effect, studies on cognitive rigidity, emotional intelligence research, and the psychology behind locus of control. If you’re interested in human behavior, intelligence, mindset, maturity, or self-growth, this breakdown will help you see people’s thinking patterns in a completely new way.

Whether you want to improve your own thinking, understand others better, or simply love psychology-based content, this video will give you real clarity about why some people argue, react, and behave the way they do — even when they’re wrong.
