Cockwomble I didn't either! I clocked the photos were old ones but didn't spot the video.
I do think its a rather interesting example though.
The number of women who thought the models were plus sized or bigger than normal was interesting; even though they weren't. I think it shows some women can't tell the difference from a photograph - some can, some can't - so when we are judging what are we actually judging against? A photo or an idea in our heads?
If its an idea in our heads, thats not about what we are ACTUALLY seeing its about the message we are receiving with it that is influencing us.
It also shows that if you see yourself in a picture are you always able to accurately gauge your size or is a photo an unreliable bit of evidence as whats in your head is more influential and can overrule what you are actually seeing.
