You cannot make any decisions without emotions
In this video Daniel Goleman is giving examples about the role of emotions in decision making. One very interesting example is the very first case in the video. It’s about a high IQ lawyer who went through a brain surgery and lost the connection between his amygdala (“emotional brain”) and prefrontal cortex (“rational brain”). His IQ remained completely intact. There was no change in his motor skills. After the operation he was able to deliver, as he was prior to the operation, brilliant rational pros and cons to the topics discussed. The difference was that he simply was not able to decide which was the best. This is one of the cases proving the role of emotions in decision making. Furthermore the decision making ability, call it emotional intelligence, can be developed. In contrary to IQ, which is inherited in your genes.
