The study looked at whether being told to "be yourself" affects how accurately people perceive your personality in first impressions. They had some people be themselves in a video interview and others not. The results showed that being yourself led to others seeing you more accurately, especially in aspects that are easy to observe and judge. However, it didn't change how likable you were or how you felt after the interview. So, being yourself can help others understand your personality better at first, but it might not have immediate personal or social effects.
