Are You “Hot or Not”?

The article discusses on the experiment done to test whether subtle changes in one's look could have a significant effect on one's attractive rating on HotOrNot. Three male and three female college-aged models were used for the experiment wherein they took a variety of photos of the models holding constant the background, lighting, pose and clothing, and subsequently changing one characteristic of the model. All 66 photos were put on HotOrNot for several weeks wherein it accumulated more than 300 votes on each female photo, and between 100 and 200 votes on each male photo. After all votes were gathered, separate OLS equations were used to explain female and male rating with dummy variable account for each treatment and model.
