“If individuals differ in the general tendency to like versus dislike objects, an intriguing possibility is that attitudes toward independent objects may actually be related,” they write. “So someone’s attitude toward architecture may in fact tell us something about their attitude toward health care because both attitudes would be biased by a disposition to like or dislike stimuli.”

So... Haters gotta hate! It really is true!

I love this:

After marking the dependably hateful haters with a scarlet H, the researchers presented participants with information about a new product: the “Monahan LPI-800 Compact 2/3-Cubic-Foot 700-Watt Microwave Oven.” This elaborately-titled microwave oven does not exist (except in Jack Donaghy's mind), but participants didn't know this, and were given three glowing fake reviews and three dissatisfied fake reviews. While people who more or less liked taxidermy and crossword puzzles also liked the oven, the haters drenched their fake consumer surveys in haterade. They were also more likely to hate on recycling and vaccine shots. (To be fair, it’s hard to be a ray of sunshine when you’ve got the measles.)

That's from Slate:

Is it wrong to love haters?

Embrace the person, eschew the hate.  Use a fantasy crowbar to separate the two.
