Personality is something that individuals are inclined to consider significantly. When people meet new individuals, whether at work, school, or social events, it is often their personality which they instantly center on. Assessing if they are polite, accommodating, sociable, or timid are a few of the aspects people evaluate (Cervone & Pervin, 2019). This discussion discusses the factors that significantly influence personality development and the least aspects that influence an individual’s personality. It is an individual’s personality that makes them who they are.

According to Cervone and Pervin (2019), the three factors that significantly influence personality development include heredity, surroundings, and circumstances. Heredity refers to the influences with which people are born with. They are an individual’s genes, and it is impossible to change these traits. Heredity often includes temperament, which assists in determining how a person reacts and how easygoing they are (Smederevac et al., 2020). Genetics also has more sway than parents in determining an individual’s personality.

Moreover, the widely unrecognized environmental influences, described as the “nonshared environmental effects,” are also considered to impact personality profoundly.  Finally, are the circumstances. Situations are the encounters that people experience. They may include trauma, divorce, death, and happy moments (Cervone & Beck, 2020). All these circumstances have a significant role in developing an individual’s personality.

The factor that has a lesser impact on how a human’s personality develops is culture. Although some studies may argue that culture is significant in shaping personality, in the 21st century, people tend to learn new cultures; thus, they can change from their original cultural practices to modern forms. According to Cervone and Beck (2020), culture is associated with a shared system of beliefs, attitudes, attributes, values, professions, and customs that define a group characteristic.

Generally, the main influences of personality development are heredity, circumstances, and environment. On the other hand, culture least influences personality but is also essential in personality growth.
