FIALA: Is the Evidence for the Lack of Impact of Microfinance Just a Design Problem?

Microfinance is one of the most hotly debated interventions in developing countries over the last 20 years. These are generally small loans, often given to women with short repayment periods and high interest rates (though often much lower than local…

GOODMAN: Ladies and Gentlemen, I Introduce to You, “Plausibility Limits”

Confidence intervals get top billing as the alternative to significance. But beware: confidence intervals rely on the same math as significance and share the same shortcominings. Confidence intervals don’t tell where the true effect lies even probabilistically. What they do…

GOODMAN: What’s the True Effect Size? It Depends What You Think

What’s the true effect size? That’s my bottom line question when doing a study or reading a paper. I don’t expect an exact answer, of course. What I want is a probability distribution telling where the true effect size probably…

FIDLER & MODY: The repliCATS Bus – Where It’s Been, Where It’s Going

For several years now scientists—in at least some disciplines—have been concerned about low rates of replicability. As scientists in those fields, we worry about the development of cumulative knowledge, and about wasted research effort. An additional challenge is to consider…
