The way we present ourselves often determines what others think of us. This is true even if you’re a person whose face and demeanor have very little to do with the person you actually are. This is why social science is so important. It allows us to see how outsiders see us without the subjectivity of how we see ourselves. A recent study just revealed that the way we smile has a lot to do with how we’re perceived, regardless of how we actually are.This study had a bit less to do with social science and psychology and a lot more to do with marketing. However, this study can actually teach us a thing or two about how other people see us. It turns out that the way we smile can make people think we’re smart or stupid. However, if you’re a person with a smile that makes you look less intelligent than you are, you shouldn't worry about it. It turns out you’re also a person with some distinct advantages in life if you have that type of smile. Here’s how the way we smile can make people think we’re smart or dumb, based on science.
