IntroductionThere are universal emotions experienced by every individual across the world. Examples of such emotions can be listed as fear, anger, disgust, sadness and so on. People are born with those emotions and those emotions have evolved to serve as a mechanism that would help individuals cope with certain obstacles they face in the environment in which they live. Every emotion has a purpose in the survival of the individual. (Darwin 1872/1965; Ekman, 1992, 1999; Izard, 1991, 1992; Tomkins & McCarter, 1964). Although these emotions are universal and known to be experienced by every individual, each person has different levels of sensitivity towards signals that trigger fear, disgust or anger. It is believed that these differences are due to the characteristics of the environment in which each person lives (Abe & Izard, 1999). Disgust is one of the universal emotions mentioned above. The evolutionary purpose of the emotion disgust is the avoidance of contaminants. The human body has parts that are sensitive to things that give us clues about containing pathogenic and/or potentially harmful agents (Kavaliers, Choleris, & Pfaff, 2005; Kiesecker, Skelly, Beard, & Preisser, 1999). Humans perceive visual, olfactory and tactile signals from the environment in which they live and make choices relevant to their observations. The color of a rotten fruit, the smell of an animal carcass or the sensation of a sweaty palm shaking originate from this disgust mechanism that makes the individual less vulnerable to disease. In the presence of pathogens containing things around, the disgust mechanism causes the body to give certain types of reactions such as nausea, loss of appetite and so on, which would make the individual avoid the risk of contamination. Here we have a problem where an individual experiences...... middle of paper......ntry (Fincher, Thornhill, 2012). When we apply error management theory here (Haselton & Buss, 2000), we can conclude that the results are as follows: living in a place where the prevalence of pathogens and diseases is high, in order not to contract a disease or become contaminated, people become more restrictive and conservative towards people they identify as different from them. Even though members of our group cannot be classified as pathogens that bring potential harm (such as rotting food, animal carcasses, bodily fluids), interpersonal disgust becomes involved and people begin to discriminate against group members and become conservative. , score lower on the personality trait openness (Druschel & Sherman, 1999; Duncan et al., 2009). In this cross-cultural study, we sought to investigate political ideology, pathogen avoidance, disgust sensitivity, and attitudes toward outgroups..
