Personality trait shapes why haters hate
New research suggests that our individual personality, or dispositional attitude, may define our general like or dislike for things around us. According to a study published in the Journal of Personality and Social Psychology, a person's attitude towards two distinctly different things may be the same simply because the attitude is being formed about these things by the same person. Positive people tend to see the positive features in something, whereas negative people are more prone to see the negative ones.
The study's authors created a scale that required people to report their attitudes toward a wide variety of unrelated stimuli, such as architecture, cold showers, politics, and soccer. Upon knowing how much people liked or disliked these specific things, the responses were then averaged together to calculate their dispositional attitude (how much they tend to like or dislike things in general). Throughout the study, the researchers found that people with generally positive dispositional attitudes are more open than people with generally negative dispositional attitudes.
Practically, this research may provide insight for marketers, for example, on why certain people may be prone to buy certain products, or why certain people follow through with positive actions, such as recycling.
