Mentalist/hypnotist Derren Brown has apparently made a series of videos called "Science of Attraction." I thought this example here was worth watching. Two separate groups of girls are shown a dating video of one guy. He say exactly the same words in both videos, but, in fact, they are two distinct 'performances." In one, his tone is upbeat and enthusiastic, in the other, more cynical and negative. https://www.youtube.com/watch?v=8VwPREpWleA I'm not sure this actually illustrates the Halo Effect very well, but it does illustrate that, when it comes to attractiveness, the way you do something is sometimes more important than what you do.
