Joining the fractious debate over how to do science best
At the end of the month (March 2019) the American Statistical Association will publish a special issue on statistical inference “after p values”. The goal of the issue is to focus on the statistical “dos” rather than statistical “don’ts”. Across…
Sizing up behavioral neuroscience – a meta-analysis of the fear-conditioning literature
Inadequate sample sizes are kryptonite to good science–they produce waste, spurious results, and inflated effect sizes. Doing science with an inadequate sample is worse than doing nothing. In the neurosciences, large-scale surveys of the literature show that inadequate sample sizes…
Internal Meta-Analysis: The Latest
I recently wrote in favour of internal meta-analysis, which refers to m-a that integrates evidence from two or more studies on more-or-less the same question, all coming from the same lab and perhaps reported in a single article. The post…

A recent powerful blog post (see below) against internal meta-analysis prompts me to ask the question above. (Actually, Steve Lindsay prompted me to write this post; thanks Steve.) In ITNS we say, on p. 243: “To carry out a meta-analysis…
Eating Disorders Research: Open Science and The New Statistics
I’m in Sydney, the great Manly surf beach just over the road. It’s an easy ferry ride to the Opera House and city centre. Lindy and I started this trip up from Melbourne with a few days with a cousin,…
Cochrane: Matthew Page Wins the Prize!
Years ago, Matthew Page was a student in the School of Psychological Science at La Trobe University (in Melbourne), working with Fiona Fidler and me. He somehow (!) became interested in research methods and practices, especially as related to meta-analysis.…

New study replicates 75 correlations between self-reported personality traits and self-reported life outcomes.
Most (87%) associations also sig (p < .05). Yes!
