From a commenter on Microaggressions Put Under the Scholarly Microscope
To be human, interacting with other humans, is to enter a world in which as Object being perceived, we emit an infinite series of unconscious cues (how we walk, how we talk, how we look, our tone of voice, our gaze, our height, our weight, what we say, what we do, how we say & do these things, etc.). These cues are then received by the Other who, in turn, as Subject, subconsciously filters & interprets them according to an infinite set of paradigmatic beliefs, stereotypes, experiences, and insights.
They say we form first impressions within approximately seven seconds.
