00:09Alright, today we are going to talk about, is your personality in your DNA?
00:14The science behind it.
00:15Ever wonder if your personality is inherited or shaped by your experiences?
00:20The debate between nature and nurture continues, but here's what we know so far.
00:241. Inherited or learned, your personality is thought to be 30% to 60% genetic.
00:29Studies on twins show that identical twins, even if raised apart, share more traits than non-twins.
00:35Traits like neuroticism, extroversion, openness to experience, agreeableness,
00:39and conscientiousness are influenced by your DNA, according to a study.
00:43But environment matters, too, your childhood experiences and surroundings can activate
00:48certain genes that shape your personality.
00:50For example, children in harsh environments often become impulsive due to activated impulsive genes,
00:55while nurturing environments promote calmer temperaments due to different gene activation.
00:59Genomics is still new, so there's more to learn.
01:022. When does personality develop?
01:04Personality starts to form early on, rooted in temperament,
01:07which is noticeable as young as 4 months old.
01:09Temperament includes reactivity, emotional responses, and self-regulation, controlling
01:14emotions. While temperament influences personality, traits can shift throughout
01:18childhood and adulthood, with big changes often happening between ages 20 and 40.
01:233. Which traits are heritable?
01:24Scientists are still figuring out which personality traits are passed down,
01:28but genes linked to novelty-seeking, discipline, sociability, and even introversion have been
01:32identified. However, traits like extroversion, agreeableness, and conscientiousness may vary
01:38in heritability, while health-related traits like self-directedness, cooperativeness,
01:42and self-transcendence seem to be more genetic.
01:454. Can you change your personality?
01:47Yes, your personality can evolve throughout life, especially between ages 20 and 40.
01:52Even in older age, many people become more confident and emotionally stable.
01:56Therapy like CBT and forming new habits through neuroplasticity can help you
02:00change aspects of your personality if that's something you want to explore.
02:04In the end, your personality is a blend of genetics and experiences,
02:07and with the right mindset, it's something you can always shape and grow.
