Led by R. Chvaja, we found that the Russian invasion of Ukraine was associated with increased religious engagement in nearby countries, but in different groups: mainly among the religious in Czechia, and among the non-religious in Poland. shorturl.at/euxSh https://www.tandfonline.com/doi/full/10.1080/2153599X.2025.2601082?scroll=top&needAccess=true#abstract21 Apr 2026 15:10 +0000at://did:plc:qlps3ifznq4dxjlavccow6ys/app.bsky.feed.post/3mjzbcaueik2ghttps://bsky.app/profile/martinlangcz.bsky.social/post/3mjza6ak2xc2gNew paper: costly signals are not reliable simply because they are costly. Intuition may help stabilize high-cost signaling, but signal reliability seems to depend on the interaction between intuition and context-sensitive deliberation. https://www.cell.com/iscience/fulltext/S2589-0042%2825%2902810-X21 Apr 2026 14:50 +0000at://did:plc:qlps3ifznq4dxjlavccow6ys/app.bsky.feed.post/3mjza6ak2xc2ghttps://bsky.app/profile/martinlangcz.bsky.social/post/3migllu4b4s23How does religious conflict reshape moral cognition across cultures? We're hiring a postdoc to help answer that question using computational modeling (DDM, RL) across 20 countries. https://www.phil.muni.cz/en/careers/available-positions/80767 #Postdoc #CognitiveScience #ComputationalModeling #MoralPsychology01 Apr 2026 11:28 +0000at://did:plc:qlps3ifznq4dxjlavccow6ys/app.bsky.feed.post/3migllu4b4s23https://bsky.app/profile/martinlangcz.bsky.social/post/3mcyv7sy4u22rNew paper - we try to test a classic secularization theory w/ longitudinal data: is material security in early adolescence associated with later decrease in belief in God in young adulthood? tl;dr: it is, a little bit.. w/ @lnpx1thetadelta.bsky.social & R.Chvaja https://www.cambridge.org/core/journals/evolutionary-human-sciences/article/longitudinal-associations-of-material-security-and-belief-in-god-in-young-americans/7EBB39D2F19EAB61D94B13174D84798222 Jan 2026 09:37 +0000at://did:plc:qlps3ifznq4dxjlavccow6ys/app.bsky.feed.post/3mcyv7sy4u22rhttps://bsky.app/profile/martinlangcz.bsky.social/post/3mccq76tzqc2wWe’re organizing IACESR 2026 in Brno (July 1–3) — CFP closes Feb 6.
