Personality may predict if you like spicy foods

Certain aspects of an individual's personality may be a determining factor in whether they like their food plain and bland or spicy and hot, according to a new research.
The study by Pennsylvania State University set out to determine whether there was a correlation between personality types and hot-spice preferences.
Nadia Byrnes, conducted a study of 184 participants - nonsmokers ages 18 to 45 without any known issues that would compromise their ability to taste, primarily Caucasian and slightly more women than men (63 per cent).
Byrnes assessed the group using the Arnett Inventory of Sensation Seeking (AISS), a test for the personality trait of sensation-seeking, defined as desiring novel and intense stimulation and presumed to contribute to risk preferences.

Those in the group who score above the mean AISS score are considered more open to risks and new experiences, while those scoring below the mean are considered less open to those things.
The subjects were given 25 micrometres of capsaicin, the active component of chili peppers, and asked to rate how much they liked a spicy meal as the burn from the capsaicin increased in intensity.

Those in the group who fell below the mean AISS rapidly disliked the meal as the burn increased. People who were above the mean AISS had a consistently high liking of the meal even as the burn increased.

Those in the mean group liked the meal less as the burn increased, but not nearly as rapidly as those below the mean.
"Theoretically, we know that burn intensity and liking are linear related. The more irritating a compound or food gets, the less people should like it. But that's not always the case," she said.
She presented her study at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Food Expo in US.
