Author John M.Grohol’s article, “15 Common Cognitive Distortions” states that cognitive distortions means people always convinces themselves something that is true, but actually isn’t true. According to the author, “people just want to tell themselves things that sound rational, and they won’t feel bad.” The author describes these “15 common cognitive distortions” that research by Aaron Beck and David Burns. First, he mentions that filtering is people take the negative details and filtering out all the positive things in a situation. Second, he discusses about polarized thinking, polarized thinking means things are just black and white, there are no middle ground. Third, he emphasizes that overgeneralization; it means if something bad happens only once, we expect it to happen over and over again. Then, he mentions that blaming, it means people tend to blame others to make themselves feel better. Next, he discuss about global labeling, people generalize one or two qualities into a negative global judgment. Then, he talks about heaven’s reward fallacy, it means people always expect their sacrifice should be pay off. However, he also discuss about emotional reasoning, it means people always believe that what he feel must be true automatically. All in all , he emphasizes these 15 common cognitive distortions are the core of what many cognitive behavioral and other kinds of therapists try and help a person learn to change in psychotherapy.

So, she had a bad impression of the restaurant. A day, we had a conversation about foods, and I asked her about which restaurants are the best and worst you tried before. So she told me the rest
