The phrase “people don’t change” is often used to express the belief that people’s fundamental traits and behaviors are fixed and unchangeable. This belief can be traced back to ancient Greek philosophy, with the idea that people are born with a certain nature that cannot be altered. In modern times, this belief has been supported by some psychological theories, such as the theory of personality types.
However, there is also evidence to suggest that people can change. Studies have shown that people can learn new skills, change their habits, and even overcome deep-seated fears and phobias. This suggests that the belief that “people don’t change” may be too simplistic. While it is true that some aspects of personality may be relatively stable, other aspects can be more malleable and subject to change.
