These five habits do not definitively determine a person’s intelligence, but they can hinder its development. Intelligence is not a static quality nor is it limited to academic knowledge. Beyond IQ, psychology experts agree that the way we act on a day-to-day basis can reveal a lot about our cognitive development. In fact, certain apparently harmless habits could be holding back our intellectual capacity without us realising it. Various studies have identified common behaviours that are associated with poor mental performance, especially in terms of critical thinking, adaptability and continuous learning. But the good news is that these habits can be changed. We’ll tell you about the five most prominent ones and what you can do to break them.
1. Lack of curiosity
Curiosity has historically been identified as one of the essential qualities of brilliant minds. “I have no special talents. I am only passionately curious,” said Albert Einstein. And it is no coincidence: a curious person is not only interested in learning, but also asks questions, seeks explanations and actively connects with knowledge. On the other hand, those who show an indifferent attitude towards the world around them, avoid asking questions or are not motivated to discover new things, may be limiting their intellectual growth. The solution is to cultivate interest: reading, watching documentaries, talking to different people and exploring new topics are excellent ways to reactivate the mind.
2. Constant procrastination
Leaving everything for later is not only a problem of productivity, it can also be a sign that something is wrong with our ability to organize and make decisions. Chronic procrastination is linked to underdevelopment of the brain’s executive functions, which are essential for planning, setting goals and maintaining concentration. To break this cycle, psychologists recommend breaking down complex tasks into small actions, setting achievable goals and using tools such as diaries or reminders. Managing time better not only reduces stress, it also improves our ability to think clearly and make more rational decisions.
3. Difficulty adapting to change
Intelligence is also measured by the ability to adapt. People who systematically resist leaving their comfort zone, who reject the new or who cling to what they already know without questioning it, tend to have more difficulties evolving on a personal and professional level. Accepting that change is a natural part of life, being willing to try different methods or to reconsider one’s own ideas are signs of a flexible mind. This openness not only stimulates learning, it also strengthens resilience in the face of complex situations.
4. Overconfidence
Although self-esteem is positive, overconfidence can become a silent enemy of intelligent thinking. People who believe they are always right tend to reject criticism, ignore data that contradicts their ideas and close themselves off to other ways of seeing reality. Psychology warns that this attitude can slow intellectual growth. Recognizing that you do not have the absolute truth, accepting mistakes and being open to other opinions are key to developing deeper critical thinking.
5. Ignoring different points of view
Rigidity of thought not only prevents learning, it also limits empathy. People unwilling to consider different ideas — whether in everyday conversation or in a professional environment — tend to lock themselves into their own frame of reference, which impairs their ability to analyze and solve problems. Actively listening, making the effort to understand others and considering opposing arguments not only enriches our ideas, it is also an exercise in intellectual humility. Intelligence, after all, is also measured by the ability to question oneself.
