The main differences between them are: (1) IQ is IQ, which indicates a person's intelligence level; Emotional quotient is the emotional quotient, which reflects the difference of a person's emotional quality. (2) IQ reflects a person's cognitive ability, thinking ability, language ability, observation ability, calculation ability, rhythm ability, etc. That is, the ability to think rationally, judge, reason and make decisions, which is the function of the left hemisphere of the brain; Emotional intelligence mainly reflects people's ability to feel, understand, use, express, control and adjust their own and others' emotions. It is not only an irrational ability, but also a function of the right hemisphere of the brain. (3) Rational ability is a cognitive model of superficial meaning, which means that the stimulus is "registered" in the thinking center, and then reacts after thinking, consideration and reflection; On the other hand, emotion is a faster response than reason, sometimes illogical, showing conflict, and often rejecting the thoughtful and analytical reasoning of the thinking center. (4) IQ depends more on genetic factors, that is, the influence of congenital factors is greater than acquired factors; Although there are innate factors in the formation and development of EQ, the acquired social environment has a greater impact on people's emotions, that is to say, EQ is easier to change than IQ, and education is more plastic to EQ.

EQ and IQ are independent, but they are not completely opposite. There are both differences and close ties between them. We often compare people's intelligence and emotional acuity, which is a good example. Pure high IQ type, almost an exaggerated and ridiculous intellectual. They are often knowledgeable, but they are at a loss in life. Just like children, they are giants in knowledge and idiots in life. On the other hand, most people with high emotional intelligence have excellent social skills and are outgoing and cheerful; Not easy to fall into fear and anxiety; Easy to invest in people and things, compassionate; Emotional life is usually rich, but not out of line; Everyone can be satisfied with himself and others. But this kind of pure high IQ and high EQ people are rare in life, so to speak, there is no one. Research shows that in daily life, most people show different combinations of IQ and EQ, and there is a certain correlation between them. It can be said that people with high IQ will not have low EQ; People with high emotional intelligence will not have bad IQ.

People with superior intelligence have four common non-intelligence factors: ① Persistence for success; (2) the ability to continuously accumulate achievements to achieve goals; 3 self-confidence; ④ Ability to overcome inferiority complex. This shows that outstanding intellectual achievements need not only intellectual factors themselves, but also non-intellectual factors such as emotion, and will play a very important role in people's success.
