I am super guilty of this. I found this article and had to share.
We all know we make snap judgments about people based on their personality, interests, or how they look, but the new findings indicate that we make these judgments without really thinking.
Australian researchers monitored the brain waves of participants as they showed them various pictures twice, and after the second time they were asked questions about each image.
Study author Dr. Stefan Bode says, "We have found that brain activity when looking at images can encode judgments such as time reference, even when the viewer is not aware of making such judgments. Moreover, our results suggest that certain images can prompt a person to think about the present or the future."
It's thought that these snap judgments are what lead people to act impulsively.
