Goleman calls this eruption an “amygdala hijack.” The amygdala is the center of the brain that controls this response, and also controls empathy; when it feels threatened, it can respond not just irrationally, but destructively. “When Mike Tyson bit Evander Holyfield’s ear, it was a very bad business decision - it cost him $3 million. It was an amgdyala hijack.”
Here are three signs of an amgdyala hijack: strong emotional reaction, sudden onset, and “when you reflect later, you realize it was inappropriate”.
The opposite of an amgdyala hijack is emotional intelligence.
