Psychological test: Common habits that help calculate a person’s intelligence

Intelligence is a multifaceted quality, often reflected in our daily habits and behaviours. While traditional IQ tests offer a snapshot of one’s intellectual abilities, every day habits can reveal much about a person's cognitive strengths. There are some habits that not only point to higher intelligence but also provide a practical lens through which we can understand and appreciate this complex trait.Keep in mind we are not talking about educational intelligence but innate intelligence. Here are some of these habits and the studies that highlight their significance.

Curiosity is more than a mere desire to know; it’s a deep, persistent drive that leads one to explore and understand the world. A study published in the Journal of Individual Differences found that individuals with a strong inclination towards intellectual curiosity often score higher on intelligence tests. This curiosity leads them to ask questions, seek new experiences, and engage in lifelong learning, all of which contribute to cognitive growth and adaptability.
Intelligent people don’t just accept information at face value; they dive deeper to uncover underlying principles. This inquisitiveness often leads them to a broader knowledge base and the ability to think critically and creatively.


Remaining calm in stressful situations is a trademark of high intelligence. According to a study by the University of California, there is a significant correlation between emotional stability and high cognitive functioning. This ability to stay composed allows individuals to think clearly and make rational decisions, even under pressure.
Intelligent individuals often use techniques like mindfulness and meditation to manage stress, which in turn, supports better problem-solving and decision-making abilities. Their calm demeanour also aids in effective communication and conflict resolution, skills that are important in both personal and professional settings.

Flexibility and adaptability are easy indicators of intelligence. A study published in Psychological Science revealed that people who can quickly adapt to new information or environments typically have higher cognitive flexibility, a core component of intelligence. This adaptability is not just about coping with change but thriving in new and uncertain situations. Such individuals are often open to new ideas and are not afraid to modify their beliefs or strategies when presented with new evidence. This openness to change creates continuous learning and personal growth. This can also happen because they tend to not connect themselves emotionally with things that have the tendency to change with time and would affect them negatively.


Spending time alone is often seen as a sign of introversion, but it can also indicate a high level of intelligence. Research by the London School of Economics and Political Science found that individuals who enjoy solitude tend to have higher IQs. This time alone allows them to reflect, process information, and develop deeper insights.
Intelligent people use solitude to recharge and think creatively. They often engage in activities that stimulate their minds, such as reading, writing, or engaging in hobbies that require concentration and skill. This reflective practice enhances their problem-solving abilities and builds innovative thinking.

Self-discipline is a critical component of intelligence. A study in the Journal of Personality highlights that individuals with higher self-control are often more successful in academic and professional settings, proof of their cognitive abilities. This trait enables them to set goals, stay focused, and persevere through challenges.

High self-discipline means that intelligent people are capable of delaying gratification and prioritising long-term rewards over immediate pleasures. This ability to manage impulses and stay committed to their goals is a strong indicator of their cognitive strength and determination.

A good sense of humour is not just about making others laugh; it’s also a sign of high intelligence. Research from the University of New Mexico suggests that individuals who can create and appreciate humour tend to have higher verbal and abstract reasoning skills. Humour requires a complex interplay of cognitive processes, including language, creativity, and emotional intelligence.
Intelligent individuals often use humour to lead social interactions and defuse tension. Their ability to see the lighter side of life and find humour in various situations reflects their intelligence and emotional strength.
