In short, it has frequently been observed that high-IQ individuals lack "common sense," particularly when dealing with other humans. General intelligence is not just a cognitive ability; it is also a cognitive disposition. It is the tendency to make judgments and take actions that will benefit you in the long run.
Intelligence is also seen as a personal quality that can be improved through practice. One mental trainer who works with athletes claims that 90% of sports champions are smart enough, but only 10% work at being smarter. Being smart is not only about having a high IQ, but also about using your brain properly.
Common sense is defined as "the knowledge of what is appropriate or reasonable to do or to feel." The term was first used by Thomas Jefferson to describe those qualities needed by an educated person to participate in society. He believed that all people have common senses, but some people develop them further through education.
Jefferson's definition of common sense is similar to today's understanding of the term. It is considered a personal rather than a cultural attribute because it can be developed through education.
Some researchers believe that there is a relationship between intelligence and common sense. They say that people who are highly intelligent tend to avoid risky situations while trying to understand how things work.
A high IQ indicates that your reasoning and problem-solving abilities are above average and may indicate intellectual potential. An IQ of 70 or lower may indicate poor cognitive functioning. A score of 80 to 89 is said to represent "superior intelligence," while a score of 90 or higher is considered "hyperintelligence."
The IQ test measures your ability to understand and apply instructions, solve problems, analyze situations, make judgments, control impulses, show creativity, and interact with others. It is not intended to measure general knowledge or cultural understanding. The maximum possible score on an IQ test is 100.
In addition to being one of the most widely used psychological tests, the IQ test has been adopted by many organizations as a tool for hiring employees, granting promotions, identifying disabilities, and more. The American Psychiatric Association (APA) uses an individual's IQ score as a criterion for diagnosing mental disorders. People who have an IQ below 70 may be diagnosed with intellectual disability. Those with an IQ between 71 and 79 may be diagnosed with mild intellectual disability, while those with an IQ of 80 or higher are not typically diagnosed with a mental disorder.
High IQ can also be a disadvantage because it can lead to arrogance, stupidity, and other problems related to lack of empathy.
Personality and intelligence have historically been seen as separate realms of human functioning. IQ, however, appears to be a personality feature, according to research conducted over the last three decades. The study of high-IQ individuals has shown that they tend to have more varied and intense personalities than average- or low-IQ people.
Intelligence is also characterized by a tendency toward certain behaviors and attitudes. High-IQ people are more likely to show evidence of creative thinking, such as solving problems in novel ways, than average- or low-IQ people. They also tend to seek out new experiences and take risks with their lives. These characteristics are not limited to any single culture or time period. They have been observed among elite intellectuals throughout history and in many different countries around the world.
Intelligence is also associated with better performance on measures of personality. The IQ tests used to measure intelligence include questions that probe each person's memory, reasoning ability, and logic skills. These same traits are also reflected in other types of tests used to measure personality, including the MMPI-2 and the Rorschach Inkblot Test. Researchers have found that high-IQ people tend to score higher on these measures of personality than average- or low-IQ people.
Intelligence is also related to good mental health.
