I'm interested in personality. Who am I? How did I become who I am? How did everyone become who they are? Are there any common grounds between HEXACO/Big Five and other personality theories such as MBTI/Enneagram/Socionics? Is there any neurobiological basis behind these theories? What are the relationships between different types of intelligence and personality? What are the causes of personality disorders (such as BPD/ASPD)? How would neurodevelopment disorders (such as ADHD/Autism) influence our personality?... By exploring these questions, I want to develop a comprehensive personality theory that explains who we are and how we become who we are.
