We all make judgements based on skin colour
We don’t, we make judgements based on explicit and implicit stereotypes. These don’t necessarily have to have anything to do with colour and many people can be shown to hold no race based stereotypes via priming or implicit association tests.
We are all susceptible to developing stereotypes based on skin colour but we don't all actually do that.
Using blues versus brown eyes with the group shown on this show was always going to be a point of failure given that the result in dividing in such a way would place, pretty much, only white people into the blue eyed group. In the 60's, the environment this exercise took place in would have yielded far different results as the subjects would have been almost 100% white and as they could not focus on skin colour, eye colour would have been far easier to focus on. It was always going to be hard for the subjects to get passed this issue.
EXACTLY! That’s what I’ve been trying to say, race should not have come into it until it was discussed after the experiment when it was clearly explained what had happened to them.
It’s also why I think the discriminator should have been height which would have allowed for each group to be a mix of ethnicities.
