darius wants to find out whether the color of clothing people wear affects how others view them. he separates participants into three groups and has them all wear the same black pants. the first group wears red t-shirts, the second group wears blue t-shirts, and the third group wears gray t-shirts. darius then brings each participant into a room for 60 seconds, and two independent coders rate how appealing they are on a scale of 1 to 10.
