Emotional Intelligence - EQ
• The ability to perceive, understand, manage and use emotions
Talent vs Grit
• Ability to stick to long term goals
Nature vs Nurture
• Behavioural genetics
• Environment
• Phenotype - observable traits
• Genotype = genetic makeup
Twins - identical and fraternal
• Identical - more similar intelligence
• Fraternal - more differences
Nature side of debate
• Heredity - estimate of the variance in population that is due to genetics
• Heritability doesn't apply to one single person
• Not fixed - depends on time and population
• Cannot explain differences between groups
• Does not indicate that a trait cannot be modified
• In fact, if we manipulate the environment, we could change the heritability of a certain
trait
