Studying personality can find out the questions that follow:
• What affects someone's personality?
• Is a personality nature or nurture?
• How mental illness can affect personality?
• How personality can help in succeeding in life?
Personality is complex and what makes a person, be the way they are is even more intriguing. Many will say that a person is shy due to their childhood and how they were raised. However, it is quite common for siblings to have completely different personalities; even though they were raised the same. One may be extremely shy and lack confidence; whereas the other could be very outgoing and social.
Another reason to study personality is to try and determine how much is nature and how much is nurture. People believe a lot of your personality is pre-determined and is somewhat inherited, whereas others argue that life experiences are what really forms a personality.
A change in a person's personality can often be the first symptom of many mental illnesses; as someone who is suffering from depression can become very withdrawn and quiet. Therefore, studying personality can help a person spot any signs of mental illness in another person early on - which can be vital to recover and receive the correct treatment.
It is also argued that personality can be vital to people getting jobs and forming relationships; and so it is important to study why this is and what kind of personality best suits certain situations.
