Neuroticism is a personality trait characterized by emotional instability, anxiety, and moodiness. Individuals high in neuroticism may experience frequent feelings of worry, sadness, or irritability. This trait can affect how people respond to stress and challenges, often leading to heightened emotional reactions. People with low levels of neuroticism tend to be more emotionally stable and resilient. They usually handle stress better and maintain a more positive outlook on life. Understanding neuroticism can help in various fields, including psychology and personal development, as it influences behavior and interpersonal relationships.
