心理学上有一个词叫：罗森塔尔效应（不自信就去练）

Group 1 - The core concept of the article is the Rosenthal Effect, which illustrates how expectations and psychological influences can significantly impact individual performance and development [3][4][6]. - The Rosenthal Effect was demonstrated in a 1968 experiment where a list of "most promising students" was given to teachers, leading to significant improvements in the students' performance, despite the list being randomly selected [4][5]. - The change in teacher attitudes towards the students, driven by higher expectations, was the key factor in the students' improved performance [6]. Group 2 - The article suggests three methods to leverage the Rosenthal Effect for personal development: 1. Positive self-affirmation can influence behavior and outcomes, encouraging individuals to adopt a more optimistic mindset [7][8]. 2. Avoiding negative influences from people who undermine self-confidence is crucial for maintaining a positive mental state [9][10]. 3. In interpersonal relationships, providing respect, trust, and support can help others build confidence and potentially change their lives for the better [11][12][13]. - However, it also warns that excessive expectations can lead to pressure and anxiety, which may have adverse effects [14].
