The spotlight effect is the tendency for individuals to overestimate the degree to which others notice them (Gilovich & Savitsky, 1999). That is, people are egocentrically biased, or focused on themselves, and tend to believe that they somehow standout more to others than they actually do (Gilovich & Savitsky, 1999).
My hair is naturally wavy and very frizzy; most days it takes at least blow-drying if not straightening to make it look halfway decent. It sounds silly, but I remember clearly the day in the eighth-grade that I discovered the magic of a hair-straightener. Apparently I was the only one to notice. I was a little nervous after getting up early to make my newly straightened hair just perfect for school because I was absolutely positive that people would notice. I remember being nervous when I first arrived at school and excited to get to my first class where I knew people would be looking at my new hair. Although a few friends of mine thought my hair looked nice that day, it was definitely not the enthusiastic response that my eight-grade mind was expecting. I think that I honestly thought that a spotlight would be on me that day. :)
I still fall pray to the spotlight effect, but after talking to some of my friends about it this week I feel that I'm not alone. To just see what would happen, I randomly told one of my friends (who looked exactly the same way she does everyday) that she looked different to see what she would say. She told me that she was waiting when I would bring up the fact that her new makeup looked a little much. It is always kind of funny when a friend remarks about how their hair looks that day or how their face is broken out and you look up realizing that you would never have noticed.
