Reposted by @scottatyson.bsky.socialPolitical Analysis @polanalysis.bsky.social · 17/02/2025How do you know when a mechanism is externally valid? In“ Sign-Congruence, External Validity, and Replication,” @tara-slough.bsky.social and @scottatyson.bsky.social develop a framework for accumulating evidence across multiple studies and develop theoretical foundations for replication. 284

Reposted by @scottatyson.bsky.socialAlex Coppock @aecoppock.bsky.social · 05/12/2024This book changed my mind about what a random-effects meta-analysis says about generalizability. I used to think it could *show* generalizability, now I understand it *asserts* generalizability. 092

scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024We also consider recently popular extrapolation approaches that impute from an estimated treatment effect in one setting to its analogue in another setting. These methods also invoke uniting principles which are typically very strong. 000
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024Part 2 explores applications. We show that *meta-analysis* and *replication* both invoke distinct uniting principles. By making explicit the assumptions each approach invokes, we can see what is learned---or not---from each method. 100
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024We advocate for measurement perspectivism, which emphasizes that substantive phenomena are distinct from the tools we use to observe and measure them. Researchers make choices about what concepts to measure, how to observe those measures, and how to quantify those observations. 110
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024Takeaways from Part I: When studying a mechanism empirically one must consider how its influence is measured Assessing general phenomenon engages with some form of external validity Accumulating evidence requires uniting principles characterizing relationships between studies 100
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024Uniting principles are the set of arguments that relate studies both qualitatively and quantitatively. We explore two: 1. Common Concepts articulates the common mechanism across studies 2. Quantitative Connection gives the quantitative relationship uniting different findings 120
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024Evidence accumulation is about whether empirical findings, collected in one particular place and time, speak to a broader social phenomenon. We develop a new concept for evidence accumulation, uniting principles, which provide the foundation of any effort to accumulate evidence. 100
scottatyson.bsky.social @scottatyson.bsky.social · 04/12/2024Part 1 develops key theoretical concepts for evidence accumulation. Part 2 applies those concepts to meta-analysis, replication, and extrapolation 100
