When we envision the future, we tend to think that it will not change as much as it did in the past.This is to strengthen the idea that "I am in a relatively good condition in my life now and will continue to do so."This time, by analyzing the published data set (Study 1) and conducting an original online survey (Study 2), we examined the magnitude of EoHI in life satisfaction and personality traits through a comparison between the United States and Japan.

　In Study 1, Americans tended to report more past changes than future changes in life satisfaction than Japanese.Also, Americans tended to see themselves more negatively than they do now, while Japanese tended to see them positively.This is thought to be because Americans are more motivated to see themselves positively than Japanese.

　In Study 2, EoHI in personality traits was examined from the relationship between self-esteem and clarity of self-concept *.As in Study 1, Americans had higher EoHI than Japanese and tended to view themselves negatively in the past.It was also found that self-esteem and clarity of self-concept are important factors that determine the size of EoHI, and the degree of their influence varies depending on the cultural background.

　EoHI has the image that he has changed a lot in the past and is now in a relatively stable and good condition, which is expected to help maintain peace of mind.Americans tend to envision EoHI relatively more clearly than Japanese.
* A concept that expresses the degree to which you can feel your thoughts and beliefs clearly and confidently.
