Blinders Unaware

"As defined by social psychology, a schema is the automatic mental template that each one of us uses to organize the world. Schemas are our organizational and active perceptual lenses that impact what we notice, what we think about, and what we remember. Though schemas can be quite useful due to their ability to make the "awareness endeavor" smoother and more efficient, they can also serve to prohibit new and important information from entering our paradigms. Schemas impact us in ways that may or may not be consciously known to us."   (My emphasis)
