A new social science experiment:
Participants are brought in, have an EEG cap put on their head to measure electrical activity in the brain, and then they are told to watch a series of faces appearing on the screen.
Some of the faces are White, some Black and some Asian….
Afterwards the participants are shown bar graphs supposedly interpreting measurements of the electrical activity in their brains. These indicate that while the participants reacted positively and neutrally to White and Asian faces, they reacted negatively to Black faces. The 'results' seem to show that our liberal participants are somewhat racist - whether consciously or unconsciously.
These graphs are, of course, just made up.
