It is not a well established fact that people prefer symmetry of ones ears or nose, over any other thing they like to look at ...
Which is why no-one ever said it was.
So why did they choose symmetry as the criteria for judging if the people were beautiful ...
Answer: they didn't.
I could do a study tomorrow just like this one, and find people who ALWAYS choose the less symmetrical faces, and show this is people's preference.
This study was not into whether people found symmetry attractive. That has already been done.
I would start by showing them Harrison Ford and Dom Delouise and see which one they choose. Or Pierce Brosnan (he is famous for having a good side and a bad side, did you know?) and Ernest Bourgnine. And my results would fit the conclusion I want to find.
Or you could follow the scientific method ... well,
you couldn't. But one could.
Unfortunately A, you are just another one of those gullible individuals who just swallow whatever you are told is science. So you are not really able to see the problems that *** therein at all. This is a well established fact.
If it is your intention to make a fool of yourself, I guess this sort of nonsense will do as well as anything.
