What Predicts Beneficial Outcomes in Psychedelic Use? A Quantitative Content Analysis of Psychedelic Health Outcomes.

Interest in psychedelics and their possible therapeutic potential has been growing. Metaphysical belief theory asserts that these benefits stem from the adoption of comforting supernatural beliefs following a mystical experience. By contrast, predictive self-binding theory suggests that the beneficial outcomes of psychedelics are primarily driven by psychological insights. The present study tests these competing models of psychedelic benefits. We conducted a quantitative content analysis on unsolicited self-reports of psychedelic users available on Erowid.org, to examine the potential relations between psychological insight, ego dissolution, therapeutic intent, altered metaphysical belief, and enduring health outcomes. We randomly selected, coded, and analyzed two hundred forty psychedelic experience reports from the website. Path analysis using structural equation modeling showed that psychological insight, not metaphysical beliefs, uniquely predicted beneficial outcomes. Moreover, beneficial outcomes' positive relation to ego dissolution and therapeutic intent was fully mediated by psychological insight. These findings support the predictive self-binding model over the metaphysical belief model.

No Support for Two Hypotheses About the Communicative Functions of Displaying Disgust: Evidence From Turkey, Norway, Germany, and Croatia.

In recent years, researchers have discovered much about how disgust works, its neural basis, its relationship with immune function, its connection with mating, and some of its antecedents and consequents. Despite these advances in our understanding, an under-explored area is how disgust may be used to serve a communicative function, including how individuals might strategically downplay or exaggerate the disgust display in front of different audiences. Here, we generated two hypotheses about potential communicative functions of disgust, and tested these hypotheses in four countries (Turkey, Croatia, Germany, and Norway). We found no evidence in support of either hypothesis in any country. Discussion focuses on the likely falsity of the two central hypotheses, alternative interpretations of our findings, and directions for future research.

To see or not to see (again): Dealbreakers and dealmakers in relation to social inclusion.

In this study, we replicated what is known about the relative importance of dealbreakers (i.e., traits avoided) and dealmakers (i.e., traits sought) in romantic and sexual relationships and extended it to an examination of self-reports of mate value, self-esteem, and loneliness. In two experiments (N = 306; N = 304) we manipulated the information people were told about potential partners and asked them about their intentions to have sex again with or go on a second date with opposite sex targets. People were less interested in partners after learning dealbreakers, effects which operated more strongly in the long-term than short-term context, but similarly in men and women. People who reported less self-esteem or more loneliness were more receptive to people with dealbreakers. People who thought they had more mate value, more self-esteem, or less loneliness were more receptive to dealmakers. Results are discussed using sociometer, prospect, and sexual strategies theories.
