It is very difficult to draw conclusions about a person you see for the first time, and if you have to evaluate his intellectual abilities.
It is especially difficult to draw conclusions about the IQ of an interlocutor if there are problems with self-esteem.
In this case, you should pay attention to the subtle signs of a stupid person. You don't have to be Einstein to figure it out.
Signs of a not very smart person
1. Often these people lack a sense of humor. It is believed that its presence is a sign of high intelligence, and its absence is a sign of immature intelligence. Stupid people are more often offended by jokes and do not feel irony.
2. Stupid people are fussy and try to attract attention with vigorous activity, thereby masking their lack of intelligence.
3. Conversation is a real pain for such a person. Do not confuse with introverts, who represent the audience of grateful listeners. A fool often interrupts, turns a dialogue into a monologue and does not think about the feelings of the interlocutor.
4. These are also self-confident people, incapable of thinking logically and lacking self-criticism. In short, they know better than anyone what is right.
5. Along with low IQ, they have poorly developed empathy. They do not understand whether those around them are ready to listen to their stories or not.
And lastly, if a person is categorical in his judgments, does not get along well with others, then in this case problems with intelligence are not excluded.
