Apparently, researchers at Manchester University are seriously hard up for funding, because they recently accepted a commission from Bausch & Lomb to unlock the scientific basis of the Beer Goggle Effect. How silly we were to think it was just the fact that alcohol makes us horny and derails our judgement. I guess what we all should have been carrying to the pub in our pockets was this:
An = number of units of alcohol consumed
S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
d = distance from 'person of interest' (metres; 0.5 to 3 metres)
A score of less than 1 indicates no effect, while ugly people start getting "surprisingly" more attractive at scores above 50. A score of 100 is the max and indicates that you will probably wake up next to the Elephant Man or possibly even Rosie O'Donnell.
I imagine there are quite a few people who wish they had made us memorize this in high school instead of the Quadratic Formula...
