Determining race isn’t just a visual thing.
Discovery News recently tried to answer the question, "How can blind people perceive and understand race if they can't see?" Their findings were both interesting and eye-opening.
In Osagie K. Obasogie's book Blinded by Sight, he studied 100 people who had been blind since birth, and asked how they understand and experience race.
He continued to explain that if you asked a blind person about race, they would describe skin color and facial features.
Although many people might think the person's voice is a deciding factor in determining someone's race, Obasogie discovered this isn't true.
Many of the subjects said they had tried to rely on voice, but they were wrong more times than not.
Interestingly enough, societal experiences around family and friends heavily shaped their views of race.
Many subjects said they intentionally ask someone what their race is to make sure they won't say anything "stupid."
