- Mega Studies Need Inference by Interval (or: Point Nulls are Especially Pointless when N is Large) - I (Bob) love large-scale collaborative projects (Many Labs, Many Babies, Psych Science Accelerator, etc.). I like the teamwork involved. I like the careful deliberation over study materials. I like the large sample sizes and the hopes of investigating how psychological phenomena vary over labs, languages, and culture. Mega studies aren't… …

- A Cliff at p=.05? Recent Evidence Suggests Yes - In brief: Two studies provide yet more evidence that researchers make poorer interpretations when they focus on statistical significance testing and its .05 threshold. Statisticians make similar errors, although in some situations to a lesser extent than do other researchers. Both statisticians and epidemiologists show, in some situations, clear evidence… …

- The Shape of a Confidence Interval: Cat’s Eye or Plausibility Picture, and What About Cliff? - In brief: Curves picture how likelihood varies across and beyond a CI. Which is better: One curve (plausibility picture) or two (cat's eye)? Which should we use in ITNS2? Curves can discourage dichotomous decision making based on a belief that there's a cliff in strength of evidence at each limit… …
