Positive controls are one of the most useful tools for ensuring interpretable and fruitful research. Strangely, though, positive controls are rarely used in psychological research. That’s a shame, but also an opportunity–it would be an easy but substantial improvement for…

Precision for Planning: Great New Developments
–updated with a link from Ken Kelley to access the functions in the paper, 6/28/2018– In a new-statistics world, the best way to choose N for a study is to use precision for planning (PfP), also known as accuracy in…
Effect Sizes for Open Science
For the last 20 years or so, many journals have emphasised the reporting of effect sizes. The new statistics emphasised also the reporting of CIs on those effect sizes. Now Open Science places effect sizes, CIs, and their interpretation centre…
APS in San Fran 3: Workshop on Teaching the New Stats
Tamarah Smith and Bob presented a workshop on Teaching the New Stats to an almost sold-out crowd. I wasn’t there, but by all reports it went extremely well. Such a workshop seems to me a terrific way to help interested…

flashbulb memory: @dstephenlindsay was visiting, and we went to Geoff Cummings’s talk. As it all sunk in, we slid down our chairs in horror. The next day, I starting fixing things in my lab—but Steve started fixing all of psychological science. https://journals.sagepub.com/doi/full/10.1177/0956797619893653
Bootstrap methods are not a license to use small sample sizes:

So impressed with this statement.
So envious of the BNA--way ahead of @SfNJournals on these issues (though good steps at eNeuro).
Today I'm thankful for any graduate program whose LoR portal requires only a letter upload and none of those rating scales.
Its only p-hacking if it comes from the pihâque region of France. Otherwise it's just sparkling malpractice
New Stats blog: Replications: How Should We Analyze the Results? https://thenewstatistics.com/itns/2019/11/22/replications-how-should-we-analyze-the-results/
We examined close to 1 million confidence intervals in PubMed abstracts and found a huge and unbelievable number of intervals that were just below the magic 0.05 statistically significant threshold https://bmjopen.bmj.com/content/9/11/e032506.full, with @Jonathan_D_Wren
