Experimental manipulation of uncanny feeling does not increase adherence to conspiracy theories.

Research over the past decade has shown that endorsement of conspiracy theories (CTs) is shaped by motivated cognition processes. Accordingly, CTs are theorized to stem from compensatory processes, as individuals attempt to cope with existential threats (i.e., uncertainty, loss of control). Based on the meaning maintenance model, we investigated whether this compensatory effect could follow from epistemic threats in domains unrelated to CTs in the form of uncanniness. Feelings of uncanniness were experimentally manipulated through exposure to absurdist art and literature in a set of five studies, followed by a mini meta-analysis (Ntotal = 1,041). We conducted a final, preregistered sixth study (N = 266) manipulating uncanniness through autobiographical recall. No robust evidence for a compensatory effect was found. We discussed methodological and conceptual limitations of the meaning maintenance model, as well as boundary conditions under which conspiracy theories could have a compensatory function to deal with threats.

Three Decades of Research on Induced Hypocrisy: A Meta-Analysis.

Induced hypocrisy is a sequential, two-step, cognitive dissonance procedure that prompts individuals to adopt a proattitudinal behavior. The present meta-analysis of 29 published and nine unpublished induced-hypocrisy studies enabled us to test three key dissonance-related issues. First, is hypocrisy effective in promoting change in behavioral intention and behavior? Our analyses supported the idea that hypocrisy (vs. control) increased both behavioral intention and behavior. Second, does hypocrisy generate psychological discomfort? Results pertaining to this issue were inconclusive due to the small number of studies measuring psychological discomfort. Third, are both steps necessary to generate change? Effect sizes conform to the idea that the transgressions-only condition can increase both behavior and intention. Our meta-analysis raises a number of theoretical issues concerning the psychological processes underlying induced hypocrisy and highlights implications for practitioners.
