My dear friend and colleague @chrisdworschak.bsky.social is kicking off #NEPS2025, presenting fascinating work with @kmross.bsky.social on conflict forecasting using… music data! 🎶📈 “Rhythms to riot” is already setting the tone for a brilliant few days of peace science! #conflictforecasting

🎉 That’s a wrap! Four days of deep dives into #OpenScience, #preregistration, #replication, #reproducibility, #multiverse, & more—applied to the social sciences. Huge thanks to all participants for the energy, insights & thoughtful questions! @ugentopenscience.bsky.social @gasparugent.bsky.social

We’d tackled HARKing & p-hacking—but what about statistical power? 🧠 We broke down how sample size, effect size & alpha shape our ability to detect real effects. Median power in poli sci = 10% 😬 (Arel-Bundock et al. 2024). To solve this, we introduced: 🧮 G*Power and 📦 pwr in R (recommended)

We wrapped up Day 2 with some hands-on fun: 🔍 Spotted flaws in vague prereg items 🧐 Reviewed my working paper for prereg slip-ups (yes, that was a bit selfish 🙃)—a great way to learn how to review prereg’d work! 📄 Explored both the default & qualitative @OSFramework templates together.

Advice on how to be a good reviewer of preregistered research based on Simmons et al. (2021)

We also tackled some common fears: 😱 “Someone will scoop me!” — Nah, you're ahead of them. It’s time-stamped & can be embargoed. 😬 “What if I change my mind?” — That’s science! Deviate transparently. 😟 “This doesn’t fit my method.” — Are you sure? Check all templates: help.osf.io/article/229-... ...

Why bother? Because PRs/RRs separates exploration from confirmation. 📉 Without it, we risk p-hacking, HARKing, and data dredging. #QRPs 🎯 With it, we build credibility, clarity, and cumulative science. #TrustScience 🙋‍♀️ Selfish reasons: www.psychologicalscience.org/observer/sev...
