Signs of low IQ in children

Human thinking is maintained through intelligence, but some people experience a decline in intelligence and lack of sensitivity in thinking. This is a common sign. Children with low IQs often show slow reactions, are unable to express themselves clearly, and use crying to vent their emotions. Parents need to guide them slowly. As long as it is non-pathological, they can recover on their own.

"People" cannot express themselves, so the question raised by the questioner is actually a manifestation of the lack of "logical thinking ability in intelligence". The normal way of asking should be:

"In what aspects do people with low IQs usually behave in ways that demonstrate their low IQs?" This way, you can ask rigorous questions about specific examples of these aspects in the problem description.

Moreover, low intelligence and low IQ may be used interchangeably only in daily language, but strictly speaking, the level of IQ cannot be measured through daily observation, because the word IQ itself refers to a numerical value in the test.

Intelligence Quotient (IQ) is a score measured by a series of standardized tests to measure a person's cognitive ability ("intelligence") for their age group. It was invented by Alfred Binet (1857-1911) of France and his students. Based on the results of this test, he set the average IQ of the general public as 100. According to this test, the IQ of normal people is mostly between 85 and 115. Intelligence is controlled by genes and cannot be changed artificially.

"People with low IQ have low intelligence" is just a potential consensus in daily life, but in fact there are still many doubts about the "IQ" statement. In other words, "People with low IQ have low intelligence" is not a consensus that all mankind can reach.

So strictly speaking, this question itself should not be valid. Even if it is valid according to the literal meaning, then I think the only possible answer is: "People with low IQs usually behave in ways that demonstrate their low IQs, usually in IQ tests."

In addition, in daily life, our judgments are basically based on subjective judgments, especially the judgments of other people's intelligence. Since our intelligence levels are not completely on the same level, our judgments of other people's intelligence will be different. "A person's behavior may seem stupid to some people and wise to others." This is very possible. If someone says that this person has a low IQ or low intelligence, I think the insult is more than the actual judgment. Therefore, I also think that the potential answers to this question should not be discussed and there is no need to discuss them because they are too subjective and are likely to lead to a war of words rather than discussion.
