Final answer:
While controversial, emotional intelligence is considered by some researchers to be a better predictor of personal and professional success than traditional IQ. It encompasses understanding of personal and others' emotions, empathy, and social skills, all essential for success in various life aspects.
Step-by-step explanation:
The statement that Emotional Intelligence (EI) makes an even greater difference than intelligence quotient in a person's personal and professional success can be considered true, according to some researchers. Emotional intelligence includes the ability to understand your own emotions and those of others, demonstrate empathy, comprehend social relationships and cues, and regulate personal emotions while responding in culturally appropriate ways. People with high emotional intelligence are often found to have well-developed social skills, which can be crucial for success in various areas of life.
Studies and experts such as Daniel Goleman suggest that emotional intelligence can be a better predictor of success than traditional measures of intelligence, like IQ. Moreover, traits like grit and perseverance have also been shown to be significant predictors of academic and personal achievement, possibly even more so than talent or IQ alone. Though the concept of emotional intelligence has been debated, its impact on success cannot be completely disregarded.
