Which person wrote a book entitled Emotional Intelligence: Why It Can Matter More Than IQ, which blended several different psychological qualities with emotional intelligence (EI) and led to conflicting definitional and measurement models of EI within the field of psychology

Answer: Daniel Goleman

Explanation: Daniel Goleman is a psychologist who wrote a book about how people's vision of intelligence is short in terms of only taking the IQ to determine a person's abilities. He suggests that we extend our vision about intelligence and start taking into consideration everyday life abilities, emotional abilities, etc to further extent the concept of "intelligence".
