Here's what bias looks like:
A long time ago I worked at a school in one of the richest neighborhoods in San Francisco.
Top of the hill. Views of the bay, the bridges, the East Bay hills.
400 boys. About 360 of them rich and White.
To get to work, I rode the BART train from Oakland to downtown SF, and the MUNI bus up the hill to the school.
I loved it. The reading time. The humanity. The dynamism. The urban serendipity.
A colleague of mine lived in Marin. She drove across the Golden Gate Bridge. She would never take the train or the bus!
"All those germs! All those. . .people. Gross!"
The implication was clear.
The germs from five-year-old rich White boys who have been picking their noses and then touching door knobs and railings and walls and desks and each other. . .
That's not gross.
And fourteen-year-old rich White boys who have been touching who-knows-what parts of their bodies, and then shaking your hand and giving you high-fives. . .
No germs there.
And the hundreds of other rich White boys touching. . . well, everything.
Nothing to be concerned about there.
Rich White people don't have germs. They're not gross.
It's only gross and germ-y when the people are poor and Black and unsophisticated and unfortunately have to ride the bus.
