A recent article in The Sydney Morning Herald explores the concept of "coolness" and how it varies among individuals. According to psychologist Dr. Helen Fisher, being "cool" is a complex trait that encompasses confidence, charisma, and a sense of style. Research suggests that people who are perceived as cool tend to have a unique combination of traits, including a strong sense of self-assurance, a willingness to take risks, and an ability to connect with others on a deep level. For example, singer-songwriter Harry Styles has been described as "cool" due to his confidence and charisma on stage, while social media influencer Kylie Jenner's style and confidence have contributed to her reputation as a cool individual.
