12 Significant Signs Of Low Intelligence

Written By Shahzaib Arshad

What are the signs of low intelligence? Not everyone has the same level of intelligence. While some individuals are highly intelligent, others may have lower levels of cognitive functioning.

This article aims to explore eight signs that indicate low intelligence. These signs may manifest in various aspects of an individual’s behavior. 

12 Signs Of Low Intelligence

Individuals with low intelligence tend to lack Curiosity and show little interest in learning new things.

Additionally, they may avoid thinking critically and exhibit a limited ability to engage in critical thinking.

Lastly, people with low intelligence may struggle to change their minds or adapt their beliefs when presented with new information or evidence.

These traits can significantly affect personal growth and development and academic and professional success.

1. Lacking Curiosity:

A deficiency in intellectual curiosity can be a strong indicator of low intelligence.

Curiosity is an essential element of intelligence; without it, one may miss out on opportunities for growth and development.

Intellectual curiosity

There are various reasons why some people lack Curiosity, including what researchers call “curiosity killers.”

These include fear of the unknown, anxiety, and stress. Exploration ignorance also contributes to a lack of Curiosity.

Individuals may not have been exposed to different ideas or experiences that would spark their interest.

Inquisitive inactivity and uninterested discovery are also factors that lead to closed-mindedness.

Moreover, lacking Curiosity makes it difficult to learn new things and expand one’s knowledge base.

People not interested in exploring new ideas tend to remain stagnant in their thinking patterns, limiting their understanding of the world around them.

They may also struggle with problem-solving skills as they do not possess the critical thinking abilities to generate creative solutions.

Therefore, individuals need to cultivate a sense of intellectual Curiosity by continually exposing themselves to diverse experiences and learning opportunities.

2. Not Interested In Learning:

Individuals who lack interest in learning may miss out on valuable opportunities for personal growth and development.

Learning motivation is crucial in an individual’s willingness to learn new things and acquire knowledge.

Without proper motivation, individuals may struggle to find the drive to learn, resulting in missed opportunities for intellectual growth.

Different learning styles can also impact an individual’s ability to engage with educational materials.

For example, some individuals are visual learners who benefit from diagrams and pictures, while others prefer auditory or kinesthetic learning styles.

Unfortunately, several barriers can hinder an individual’s desire to learn.

These include financial constraints that limit access to education resources, limited time due to work or family obligations, and mental health issues.

These include depression or anxiety, making it difficult for individuals to focus on their studies.

However, by employing effective learning strategies, individuals can overcome these barriers and improve their academic performance.

These strategies include setting achievable goals and utilizing active studying techniques like note-taking and summarizing information,

It is also important to consider the learning environment when attempting to foster a love of learning.

A positive atmosphere encouraging exploration and Curiosity can help motivate individuals who might otherwise be disinterested in educational pursuits.

Individuals need to recognize the value of lifelong learning to avoid thinking patterns with low intelligence, such as closed-mindedness or anti-intellectualism.

By actively seeking new information through reading books, individuals can continue expanding their knowledge base into adulthood.

3. Avoid Thinking:

Avoiding the act of thinking can hinder an individual’s intellectual growth and development.

Mindless actions, blind acceptance, stagnant mindset, lack of reflection, and avoidance behavior are signs of low intelligence.

Intellectual growth  and development - signs of low intelligence

When individuals engage in mindless actions without thought or consideration, they fail to develop their cognitive abilities.

Blind acceptance refers to accepting information without questioning its validity or accuracy.

This lack of critical thinking skills can lead to a stagnant mindset resistant to change.

In addition, individuals who avoid thinking to miss out on opportunities for growth and learning.

Lack of reflection is another sign of low intelligence, as it indicates a failure to evaluate one’s thoughts and behaviors critically.

Instead, individuals may avoid them by distracting themselves from difficult tasks or situations rather than confronting them head-on.

Ultimately, these signs can prevent an individual from developing the critical thinking skills necessary for success in academia or the workplace.

Critical thinking skills can also lead to poor decision-making and problem-solving abilities.

4. Lacking Critical Thinking:

The absence of critical thinking skills can hinder an individual’s ability to make informed decisions and solve complex problems.

Logical fallacies, cognitive biases, and poor reasoning skills show how lacking critical thinking can lead to flawed decision-making.

Below are four common ways that individuals may exhibit a lack of critical thinking:

1. Confirmation bias is the tendency to seek information that confirms one’s pre-existing beliefs rather than considering alternative viewpoints.

2. Hasty generalization is concluding insufficient evidence or small sample size.

3. Ad hominem attacks are attacking the person making an argument rather than addressing the argument itself.

4. Appeal to authority is accepting something as true simply because an authority figure says it without critically evaluating the evidence.

Without these essential thinking skills, individuals may struggle with problem-solving and making sound decisions in personal and professional contexts.

This lack of critical thinking often leads to individuals not changing their minds even when presented with new information or evidence contradicting their beliefs.

5. Not Changing Their Mind:

Resisting new information and perspectives can limit intellectual growth and adaptability to changing circumstances.

Stubbornness, the tendency to cling to preconceived notions despite evidence that contradicts them, is often associated with low intelligence.

Conversely, open-mindedness, or the willingness to consider multiple viewpoints and adjust one’s beliefs, is a hallmark of intelligence.

The difference between fixed and growth mindsets also plays into this subtopic.

Those with a fixed mindset are more likely to be rigid and less willing to change their minds when presented with new information.

On the other hand, those with a growth mindset tend to be more flexible and open-minded, viewing challenges as opportunities for learning rather than setbacks.

6. Lack Of Common Sense:

A firm grasp of common sense is crucial for navigating daily life and making sound decisions.

Individuals who lack this quality may struggle with basic problem-solving tasks and can often make irrational choices.

Common sense

Real-life examples of the negative impact of low common sense can be seen when individuals engage in risky behavior.

This may include driving under the influence or taking dangerous drugs.

Such actions not only put their own lives at risk but also endanger the lives of others.

Moreover, lacking common sense can have significant societal and workplace implications.

Employers seek employees capable of critical thinking and decision-making in today’s fast-paced world.

Employees who lack these skills may struggle to perform job tasks effectively, which could lead to poor performance reviews or even job loss.

As such, educational approaches focusing on developing critical thinking skills early could help prevent the development of low common sense in individuals.

Personal development strategies such as mindfulness meditation or cognitivebehavioral therapy can help individuals improve their reasoning ability.

7. Not Interested In Innovations:

Individuals who do not show interest in adopting innovations may struggle to keep up with the ever-changing demands of modern society.

Innovation stagnation can lead to a lack of adaptability, change resistance, and experimentation aversion.

Those with this mindset often fear newness and prefer sticking to familiar and comfortable things.

It is important to note that while some people are naturally inclined towards innovation, others may require encouragement or guidance before embracing it.

The reluctance towards innovation can be detrimental in various aspects of life, including personal growth and career development.

In today’s rapidly evolving world, it is crucial for individuals to constantly learn and innovate if they wish to remain relevant and competitive.

Failing to do so can result in being left behind by peers who are more willing to embrace change.

Hence, those who exhibit signs of low intelligence due to their lack of interest in innovations should consider exploring ways to expand their horizons.

They should overcome their fears of trying something new.

8. Creatively Stuned:

Creatively stunned individuals may face challenges in producing innovative ideas and may benefit from strategies to foster creativity.

Such individuals may struggle with imaginative thinking, limiting their ability to generate creative solutions or offer unorthodox ideas.

One of the key indicators of low intelligence is a lack of creativity.

Many studies have shown that less intelligent people tend to be less creative, as they often rely on conventional methods and thought patterns.

In contrast, highly intelligent individuals tend to be more open-minded and willing to experiment with new ideas and approaches.

They are also more likely to engage in artistic expression and innovative problem-solving.

It allows them to explore new possibilities and come up with unique solutions.

Therefore, it is important for those who are creatively stunned to seek opportunities for growth and development.

They must engage in activities encouraging imaginative thinking, such as brainstorming sessions or other collaborative creativity exercises.

9. Poor Memory Retention:

Individuals with poor memory retention may struggle to retain and recall information over time.

They may find it difficult to remember details, facts, or instructions, leading to academic, professional, or daily life challenges.

Poor memory retention - signs of low intelligence

Memory retention issues can stem from various factors, such as a lack of focus, ineffective learning strategies, stress, or certain neurological conditions.

These individuals might require alternative learning methods, such as visual aids or repetition, to enhance their memory recall.

It’s important to note that poor memory retention does not necessarily indicate low intelligence, as intelligence encompasses a wide range of cognitive abilities.

10. Limited Adaptability:

Limited adaptability refers to an individual’s difficulty adjusting to new situations or environments.

They may struggle to cope with changes, find it challenging to develop new routines, or resist unfamiliar experiences.

This can be due to a preference for familiarity, fear of the unknown, or a rigid thinking style.

Limited adaptability can impede personal growth, hinder problem-solving abilities, and create difficulties in social and professional interactions.

Developing adaptability skills often involves exposure to new situations, cultivating open-mindedness, and learning to embrace change.

It’s important to remember that adaptability is a skill that can be developed with practice and experience.

11. Lack Of Verbal Fluency:

A lack of verbal fluency refers to difficulties expressing oneself clearly and coherently through spoken or written communication.

Verbal fluency - signs of low intelligence

Individuals experiencing this challenge may struggle to find the right words, organize their thoughts, or articulate ideas effectively.

This can lead to misunderstandings, frustration, and reduced opportunities for self-expression.

Factors contributing to this issue may include limited vocabulary, anxiety, cognitive processing difficulties, or language-related conditions.

Building verbal fluency may involve practicing public speaking, engaging in conversations, and working on language skills through reading and writing.

It’s worth noting that intelligence is not solely determined by verbal fluency, as individuals can excel in other areas.

12. Limited Attention Span:

A limited attention span is an individual’s difficulty sustaining focus or concentration for extended periods.

They may find it challenging to stay engaged in tasks, easily become distracted, or struggle with multitasking.

Factors such as restlessness, boredom, environmental stimuli, or underlying attention disorders can contribute to this issue.

Limited attention span can impact learning, productivity, and overall performance.

Improving attention span includes creating a conducive environment, breaking tasks into smaller, manageable segments, practicing mindfulness techniques, and developing organizational skills.

It’s important to recognize that attention span can vary depending on the task and context, and individuals may have strengths in other cognitive areas.


Low intelligence is a complex and multifaceted concept that can be difficult to quantify.

However, certain signs may indicate a lack of intellectual capacity.

These signs include poor judgment, difficulty grasping complex concepts, limited problem-solving abilities, etc.

They also include poor memory retention and recall, lack of creativity or innovation, limited communication skills, and narrow-mindedness.

While these symptoms do not necessarily indicate low intelligence, combined, they can indicate diminished cognitive ability.

It is essential to note that intelligence is not an immutable trait; it can be developed through education and practice over time.

Therefore, identifying these signs early on can help individuals work towards improving their intellectual capacities and lead more successful lives in the future.
