Final answer:
Qualities that characterize a professional person include expertise and ethical standards, and while personality traits like agreeableness and extraversion can influence professional interactions, they are not direct markers of professionalism.
Step-by-step explanation:
The qualities that characterize or mark a profession or a professional person often include expertise and ethical standards. A professional is typically marked by a high level of knowledge in their field, which contributes to their expertise. They also adhere to ethical standards that govern their professional behavior, ensuring they act with integrity and respect for their clients, colleagues, and the broader community. These qualities are critical for building trust and credibility in any profession.
Other aspects of professional behavior can include conscientiousness, characterized by organizational skills, efficiency, and goal-directed behavior, which have been correlated with academic and career success. Moreover, aspects of personality such as agreeableness and extraversion can influence professional interactions, and while these are not directly correlated with professionalism, they play a role in how professionals engage and communicate within their fields.
