Final answer:
The notion that extroverts perform better in project work than introverts is false. Conscientiousness is a better predictor of work performance, and effective collaboration benefits from a mix of personalities, influenced by leadership style and task nature.
Step-by-step explanation:
The statement that outgoing, people-oriented individuals have a better likelihood of performing well on project work than quieter, more introverted people is false. Extroversion and introversion, as explored by Carl Jung and later in the Five Factor Model of personality, indicate preferences in energy sources and interactions, but they do not necessarily predict work performance. According to the Five Factor Model, conscientiousness is one of the best predictors of work performance, which includes traits like competence, self-discipline, thoughtfulness, and achievement-striving. Also, the dynamics of project work can benefit from a variety of personality traits, including the thoughtful, focused contributions of introverts and the sociable, energetic contributions of extroverts. Previous research also indicates that the leadership style and the nature of the task might influence how well individuals perform, not just their level of extroversion or introversion.
