It is said that IQ is equal to zero when you are angry. Is there any scientific basis?
People's emotions are controlled by thinking, and the level of emotions is related to the frequency of brain wave activity. Brain wave is spontaneous and rhythmic neural electrical activity, and its frequency range is 1-30 times per second, which can be divided into four bands, namely δ (1-3Hz), θ (4-7Hz), α (8- 13Hz) and β (/kloc-). There is no completely unified standard for the frequency limit of these waves in academic circles. Some scholars think that δ wave is less than 4Hz, θ wave is 4 ~ 7 Hz, α wave is 8 ~ 12 Hz and β wave is 13 ~ 35Hz. They also believe that there are brain waves greater than 35 Hz, and named them gamma waves. People who stay in this state for a long time will be in danger. When people are angry, the frequency of brain waves is in the state of β wave 13 ~ 35 Hz. In this state, people's emotions will be out of control, their analytical ability will drop sharply, and their IQ will tend to zero.
