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.
