Five years from now I hope will remember many concepts in psychology, but I think the most memorable concept is think critically on everything I experience. Because until I read this psychology text book, I barely had can think critically on the information I get from the media or anything I experience. When I read an article or the news paper I pretty much always believed everything because that information is from the news paper and news paper never put untrue information. Therefore, when there is news about some kind new research I just believed that it is always true, and there is no doubt about that. But, after critical thinking I started to ask question about every information or experience I have. For example, now when I read article about some kind new experiment, I start ask question about it. Such as how many times did this experiment success or is there any other explanation for this experiment. Critical thinking made me see new side of the world. Therefore, five years from now critical thinking is the concept in psychology that I will never forget.
