Stein, D. H., Hobson, N. M., & Schroeder, J. (2021). A sacred commitment: How rituals promote group survival. Current Opinion in Psychology, 40, 114-120. [Science Direct Link]

  • Short Summary: This paper proposes that rituals enhance religious group survival not only by signaling external commitment but also by fostering internal commitment toward the group in three ways: (1) enhancing belief in the group’s values (‘committed cognition’), (2) increasing the desire to maintain membership in the group (‘committed affect’), and (3) increasing contributions to the welfare of the group (‘committed behavior’).

When “Enemies” Become Close: Relationship Formation Among Palestinians and Jewish Israelis at a Youth Camp [PDF]→

White, S., Schroeder, J., & Risen, J. L. (2021). When “enemies” become close: Relationship formation among Palestinians and Jewish Israelis at a youth camp. Journal of Personality and Social Psychology, 121(1), 76-94. [APA PsycNet Link]

  • Short Summary: This paper uses 7 years of data from Jewish Israeli and Palestinian teenagers attending a three-week summer camp (Seeds of Peace) to show that propinquity (here, being quasi-randomly assigned to share an activity group together) increases the formation of outgroup relationships more than ingroup relationships (1 longitudinal field study). Thus, at least in this setting, propinquity counteracted homophily.

To Build Efficacy, Eat the Frog First: People Misunderstand How the Difficulty-Ordering of Tasks Influences Efficacy [PDF]→

/

Habbert, R., & Schroeder, J. (2020). To build efficacy, eat the frog first: People misunderstand how the difficulty-ordering of tasks influences efficacy. Journal of Experimental Social Psychology, 91, 104032. [Science Direct Link]

  • Short Summary: This paper shows that completing tasks in increasing-easiness order builds efficacy more than increasing-difficulty (or randomized) order, but people prefer to complete tasks in the opposing order in part because they inaccurately believe that doing so will enhance their efficacy (7 experiments).
