Just took the race one. It said I have a slight automatic preference for Europeans.
I'd like to be able to take a look under the hood of the test to be able to better determine its potential validity - particularly concerning the specific test order, as well as what timing and ordering criteria they're using within the test.
Regardless, I suspect that most people would score at least a slight automatic preference considering that studies have shown that infants pick up a racial preference for their parents race within the first few months, and it's likely that this preference becomes somewhat hardwired.
All this aside, I don't think scoring a preference necessarily makes one either racist or bigot, as a slight, subconscious preference wouldn't necessarily be an indicator of larger or deeper conscious attitudes or behaviors.
