12 Signs of an Unintelligent Person According to Science

Intelligence is a multifaceted concept, encompassing cognitive abilities, problem-solving skills, adaptability, and emotional intelligence. While there is no single definitive measure of being unintelligent, research has identified certain characteristics and behaviors that may be associated with lower cognitive abilities. It’s important to note that these are not absolute indicators, and individual differences can vary greatly.  

1. Closed-mindedness:

One sign of lower intelligence is a rigid adherence to one’s existing beliefs and opinions. Intelligent individuals are open to new ideas, willing to consider alternative perspectives, and capable of adjusting their views based on evidence. In contrast, those with lower cognitive abilities may be resistant to change, dismissive of opposing viewpoints, and unable to engage in constructive dialogue, as detailed on Medium.

Effective communication involves both expressing oneself and actively listening to others. Individuals with lower intelligence may struggle with attentive listening, often interrupting, jumping to conclusions, or focusing solely on their own thoughts. This hinders their ability to learn from others, build meaningful relationships, and engage in productive conversations.  

3. Difficulty understanding abstract concepts:

Abstract thinking involves the ability to grasp complex ideas, consider hypothetical scenarios, and engage in theoretical reasoning. This is often associated with higher intelligence, while individuals with lower cognitive abilities may struggle to comprehend abstract concepts, preferring concrete and tangible information.  

4. Lack of curiosity:

A thirst for knowledge and a natural inclination to explore new ideas are hallmarks of intelligence. Individuals with higher cognitive abilities are often curious, eager to learn, and actively seek out information. In contrast, those with lower intelligence may be complacent, content with their existing knowledge, and disinterested in expanding their intellectual horizons.  

5. Poor problem-solving skills:

The ability to identify, analyze, and resolve problems effectively is a key aspect of intelligence. Individuals with higher cognitive abilities are often resourceful, adaptable, and able to think critically to find solutions. Those with lower intelligence may struggle with problem-solving, resorting to impulsive decisions, and emotional reactions, or avoiding challenges altogether.  

6. Difficulty adapting to change:

Life is constantly evolving, and the ability to adapt to change is essential for success. Intelligent individuals are typically flexible, open to new experiences, and capable of adjusting their strategies when circumstances change. Those with lower cognitive abilities may be resistant to change, clinging to familiar routines and struggling to cope with unexpected events.

Impulsive behavior, characterized by acting without thinking, can be a sign of lower intelligence. Intelligent individuals are often thoughtful, and deliberate, and consider the potential consequences of their actions before making decisions. Those with lower cognitive abilities may be prone to rash decisions, emotional outbursts, and impulsive behaviors that can lead to negative outcomes.

8. Overconfidence:

While confidence can be a positive trait, excessive self-assurance can be a sign of lower intelligence. The Dunning-Kruger effect suggests that individuals with limited knowledge or competence may overestimate their abilities, while those with higher intelligence are often more aware of their limitations and open to learning from others.

9. Poor emotional regulation:

Emotional intelligence, the ability to recognize, understand, and manage one’s own emotions and the emotions of others, is an important aspect of overall intelligence. Individuals with lower cognitive abilities may struggle with emotional regulation, experiencing mood swings, difficulty empathizing with others, and difficulty coping with stress.  

10. Lack of self-awareness:

Self-awareness involves understanding one’s own strengths, weaknesses, values, and motivations. This is essential for personal growth, self-improvement, and building healthy relationships. Individuals with lower intelligence may lack self-awareness, struggling to identify their own emotions, biases, and limitations.  

11. Inability to learn from mistakes:

Everyone makes mistakes, but the ability to learn from them is a key aspect of intelligence. Intelligent individuals are often reflective, able to analyze their errors, and adjust their behavior accordingly. Those with lower cognitive abilities may repeat the same mistakes, failing to recognize patterns or learn from their experiences.

12. Difficulty understanding different perspectives:

The ability to see the world through the eyes of others is crucial for empathy, compassion, and effective communication. Individuals with higher intelligence are often able to consider different viewpoints, understand cultural differences, and appreciate diverse perspectives. Those with lower cognitive abilities may struggle with this, clinging to their own beliefs and judging others based on their own limited worldview.
