The third explanation proposes that thin-slicing provides accurate judgments simply because they are snap judgments. Being exposed to only a thin-slice of behavior eliminates the presence of distracting stimuli such as verbal interaction and doesn't allow the rater time to introspectively reason out why they judge an individual a certain way, which may cause them to overthink and change the judgments formed by their initial instincts. Thin-slicing allows raters to focus on expressive behavior and weeds out extraneous information that can cause judgments to stray away from the truth.
