The hype cycle starts again

Completely uncritical press coverage of a speculative analysis. But, hey, it was published in the prestigious Proceedings of the National Academy of Sciences (PPNAS)! What could possibly go wrong? Here’s what Erik Larsen writes: In a paper published in the Proceedings of the National Academy of Sciences, People search for meaning when they approach a […] The post The hype cycle starts again appeared first on Statistical Modeling, Causal Inference,…

Replication controversies

I don’t know what ATR is but I’m glad somebody is on the job of prohibiting replication catastrophe: Seriously, though, I’m on a list regarding a reproducibility project, and someone forwarded along this blog by psychology researcher Simone Schnall, whose attitudes we discussed several months ago in the context of some controversies about attempted replications […] The post Replication controversies appeared first on Statistical Modeling, Causal Inference, and Social Science.

Ray Could Write

Now he is scattered among a hundred cities And wholly given over to unfamiliar affections, To find his happiness in another kind of wood And be punished under a foreign code of conscience. . . . You were silly like us; your gift survived it all: For chess makes nothing happen: it survives In the […] The post Ray Could Write appeared first on Statistical Modeling, Causal Inference, and Social…

The Fault in Our Stars:  It’s even worse than they say

In our recent discussion of publication bias, a commenter link to a recent paper, “Star Wars: The Empirics Strike Back,” by Abel Brodeur, Mathias Le, Marc Sangnier, Yanos Zylberberg, who point to the notorious overrepresentation in scientific publications of p-values that are just below 0.05 (that is, just barely statistically significant at the conventional level) […] The post The Fault in Our Stars: It’s even worse than they say appeared…
