- 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. He moved to Cochrane Australia, which is based at Monash …
- Draw Pictures to Improve Learning? - In ITNS we included a short section near the start describing good strategies for learning, based on empirical studies. Scattered through the book are reminders and encouragement to use the effective strategies. Now, just as we're thinking about possible improvements in a second edition, comes this review article: Fernandes, M. …
- ITNS–The Second Edition! - Routledge, our publisher, has started planning for a second edition. That's very exciting news! The only problem is that Bob and I can't think of anything that needs improving. Ha! But, seriously, we'd love to hear from you about things we should revise, update, or somehow improve. (Of course, we'd …
- Open Science DownUnder — Fiona Fidler reports - Last week, the 2018 Australasian Open Science Conference was held in Brisbane at the University of Queensland: The first conference in Oz on the themes of Open Science and how to improve how science is done. They expected 40 and 140 turned up! By all reports it was a rip-roaring …
- A Wonderful Panorama of Statistics - Bob and I have been off-air for a while, but we haven't gone away. I've been meaning for ages to blog about a wonderful book. Here it is: Sowey, E., & Petocz, P. (2017). A panorama of statistics: Perspectives, puzzles and paradoxes in statistics. Wiley. And the flyer with succinct …
- Positive Controls for Psychology – My pitch for a SIPS project - 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 psychological researchers to start using regularly using positive controls. I …
- 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 parameter estimation (AIPE). Both our new-statistics books explain PfP and …
- 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 stage. Here's a recent article with interesting discussion and much …
- 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 stats teachers introduce the new stats into their own teaching. …
- APS in San Fran 2: Symposium on Teaching the New Stats - Our symposium was titled Open Science and Its Statistics: What We Need to Teach Now. The room wasn't large, but it was packed, standing room only. I thought the energy was terrific. There were four presentations, as below. Bob and Tamarah Smith have set up an OSF page on Getting …
- APS in San Fran 1: Open Science is Maturing - It was, as ever, a great pleasure to catch up with Bob last weekend. We were in San Francisco for the APS Convention. That convention has been for the last five years or so a hotbed of discussion about Open Science--many times I felt I was witnessing decisions about what …
- The Perils of MTurk, Part 1: Fuel to the Publication Bias Fire? - It's not going to be a popular opinion, but I think MTurk has become a danger to sound psychological science. This breaks my heart. MTurk has helped transform my career for the better. Moreover, MTurk participants are amazing: they are primarily diligent and honest folks with a genuine interest in …
- Tony Hak 1950-2018: Champion of Better Methods, Better Statistics - It was a shock to receive the very sad news that Tony Hak died last week, unexpectedly. Too young! And only 3 years into an active retirement. Tony was an Emeritus Associate Professor, having retired in 2015 from the Department of Technology and Operations Management of RSM, the Rotterdam School …
- Badges, Badges, Badges: Open Science on the March - Here are two screen pics from today's notice about the latest issue of Psychological Science. Four of the first five articles earned all three badges, including Pre-reg! Gold! (OK, by showing just those five I'm cherry picking, but other articles also have lots of badges and, in any case, what …
- ITNS–A New Review on Amazon - The ITNS page on Amazon (U.S.) is here. Scroll down to see the 4 reviews by readers. Recently a five-star review was added by Edoardo Zamuner.

- We’ve Been Here Before: The Replication Crisis over the Pygmalion Effect - [UPDATE: Thanks to twitter I came across this marvelous book(Jussim, 2012) that does a great job explaining the Pygmalion effect, the controversy around it, and the overall state of research on expectancy effects. I've amended parts of this post based on what I've learned from Chapter 3 of the book...looking forward …
- The National Association of Scholars Weighs in on ‘The Irreproducibility Crisis’ - STOP PRESS: Since first writing this post I've discovered that all may not be as it seems--especially to me at the other end of the Earth. As ever, we need to be vigilant for any dark forces wishing to use the replication crisis as an excuse to discredit science. Science …
- The Beautiful Face of a Confidence Interval: The Cat’s Eye Picture - Pawel (Pav) Kalinowski and Jerry Lai completed their PhDs a few years back. A recently published Frontiers article (citation below) reports what was primarily Pav's research on how people understand confidence intervals (CIs). The short version is "for many people, not very well, but there is hope". Kalinowski, P., Lai, …
- Measuring Heterogeneity in Meta-Analysis: The Diamond Ratio (DR) - This is a post about the Diamond Ratio (DR), a simple measure of the extent of heterogeneity in a meta-analysis. We introduced the DR in ITNS. But first, some background. Fixed Effect (FE) model for meta-analysis The diamond at the bottom of the forest plot picturing a meta-analysis reports the …
