Is the beer-goggle effect real?

Scientists paid a visit to a south London pub to conduct an experiment to find out whether the so-called 'beer-goggles' effect is real.

The phrase refers to the phenomenon where drinking too much alcohol makes people attracted to someone they would not normally be attracted to when sober.

Dr Lewis Halsey from Roehampton University got drinkers to look at photos to choose who they thought were the most attractive.
