Introduction In this study, researchers explored the relationship between eating spicy food and having aggressive thoughts. The researchers conducted an experiment in which they predicted that spicy food consumption would cause participants to have more aggressive thoughts when compared with participants who did not eat spicy food. Participants Sixty college students participated in the experiment. The researchers did not provide additional information about the participants’ race or gender identities. Method Participants were randomly assigned to eat either a plain tortilla chip (non-spicy condition) or a tortilla chip with two drops of habanero pepper1 sauce on it (spicy condition). Participants then rated how spicy the tortilla chip was, how much they liked it, and their general preference for eating spicy foods. These ratings were made on 7-point Likert scales, with higher ratings indicating greater spiciness, greater enjoyment, and greater preference for spicy foods, respectively.  Next, the participants completed a word fragment quiz. In the quiz, they were presented with a series of word fragments and were asked to choose one of two provided options to complete the fragment. One of the choices to complete the fragment was associated with aggression while the other choice was not. For example, for the fragment “H_T,” participants could choose “HAT” or “HIT.”  Across the series of word fragments, participants received a score of 0 to 10 for the number of aggressive options they chose.  Finally, participants were asked to read a brief story about a character whose behavior could be perceived as having aggressive or non-aggressive intentions. They then reported the degree to which they believed the intent of the character’s behavior was aggressive, using a 7-point Likert scale, where higher ratings indicated greater perceived aggression intentions. Results and Discussion Participants in the spicy condition were more likely to complete word fragments with an aggressive option (mean = 5.58; standard deviation = 1.88) than were participants in the non-spicy condition (mean = 3.75; standard deviation = 1.86).  The researchers also found that participants in the spicy condition were more likely to attribute the story character’s behavior to aggressive intentions (mean = 5.45; standard deviation = .86) than were those in the non-spicy condition (mean = 4.71; standard deviation = .98).  All differences reported were statistically significant.
