Inattentional Blindness Defined
Inattentional blindness is the failure to notice an unexpected stimulus that is in one's field of vision when other attention-demanding tasks are being performed. It is categorized as an attentional error and is not associated with any vision deficits. This typically happens because humans are overloaded with stimuli, and it is impossible to pay attention to all stimuli in one's environment. This is due to the fact that they are unaware of the unattended stimuli. Inattentional blindness also has an effect on people’s perception. There have been multiple experiments performed that demonstrate this phenomenon.

“Why is it so difficult to see the lesbian—even when she is there, quite plainly, in front of us? In part because she has been “ghosted”Mor made to seem invisible—by culture itself.... Once the lesbian has been defined as ghostly—the better to drain her of any sensual or moral authority—she can then be exorcised.”
—Terry Castle, U.S. lesbian author. The Apparitional Lesbian, ch. 1 (1993)
