Is it true that acting can affect one's behaviour?

For example, if someone plays a protagonist, can this affect them to be a good person? Is there any solid evidence for this?

This is true. Mot et al. (1994) published scientific research about it. Also there are a lot of actors that claim they feel that their personality has changed since they played a role.

Also a similair practice can be used for insecure people. If they act confident it has been proven that after some time, they feel more confident as well.


Since I'm new to stackexchange I did not know how much detail is desired. Therefore, let me expand upon my original comment.

The article states the following hypotheses:

(1) the actor chosen to play a given character would have personality characteristics similar to that of his or her corresponding character

(2) the actor′s self-perceived personality profile would become more similar to the character′s during the rehearsal and production period.

Later on the article states that:

Support emerged for the second hypothesis, but not for the first. Observations regarding these findings and suggestions for future explorations are given.

The article expands upon this, but I can't access the paper, because it's pay-walled.

  • $\begingroup$ @EdmundReed To break your question down further, the only difference between 'fake it till you make it' and this article is that in the article people act like a fictional character while with 'fake it till you make it' it applies to a non-fictional character. If I were to research it, my hypothesis would be that the effects would be more apparent by 'faking' since I think that people draw the line more between themselves and a fictional character than themselves and a 'fake' version of themselves. $\endgroup$
