- The joke of self-correcting science: The Andero lab and Nature Communications - In 2017, I (Bob) attended a National Academies of Science conference on reproducibility in science. Among many memorable events, I saw a talk by David Allison about his efforts to correct simple statistical mistakes in the published literature. He would notice a clear and obvious error, like a claimed interaction… …

- The Grand Challenges of Psychological Science: Climate Change - As part of its strategic planning, APS recently asked members to identify the 'grand challenges' for our discipline. I wrote, of course, about climate change. The latest APS Observer summarised responses from members from all round the world. The article is here. These are the grand challenges discussed in the… …

- Hallelujah! Physiotherapists Join the Christmas Choir of Estimation Angels! - I woke on Christmas morning to a message from Bob with this link, to this editorial: Note the number of Physio Journals represented in the authorship! Not just a single journal, but journal editors for a whole discipline! Here's the first para, highlights added: Null hypothesis statistical tests are often… …

- AIMOS: Recorded Session Gems Now Online - Bob tweeted about it, I posted about it, and recently it happened: The AIMOS zoomfest. The program is here. AIMOS, just 3 years old, advances meta-science, a big part of which is the scholarship and advocacy that advances Open Science. This is the third conference, and now, supported by a… …
- Where a Psychology Major Might Lead - The brain..., the climate crisis..., sustainability with children..., healthy homes..., RCTs..., statistical reform..., and even golf. If you have a student wondering where a psychology major might lead, suggest they have a veg out and listen to Toby's story (at that page, scroll down a little). A few waypoints: 0.50… …
- MRI Analysis, Now With Open Science - It's fabulous to see yet one more research field, MRI and fMRI, jumping on board with Open Science. The Workshop runs 13-17 December, 2021, and the site is here. Recall the dead salmon? (tiny.cc/deadsalmon, ITNS p. 485.) Back then, in 2009, a common way to analyse fMRI data relied on… …
- Meta- and Open Science at AIMOS, Soon: Get Pumped - Bob recently tweeted: "I just registered for AIMOS, the meta- and open-science conference, Nov 30-Dec 3. https://aimosconference.com/register.html ... Looking through the program, pretty easy to get pumped about AIMOS." Indeed! And not only because Bob is presenting. See the full four-day program here, including brief abstract of many contributions. Pro… …

- The Diamond Ratio (DR), Our Estimate of Heterogeneity: Now Published Online - I recently posted about our DR article being accepted by BJMSP. It has now been published online, here. It's behind a paywall, but here is the full pdf that we are allowed to share; it has only a few limitations, including no local file download. Again, well done Max! Enjoy,… …

- Sport and Exercise Science: The New Statistics, Videos, and ESCI - It’s a pleasure to see estimation, Open Science, and even use of ESCI spreading across disciplines. This blog has reported various talks and articles I’ve been involved with in fields as diverse as, for example, Antarctic and marine science, orthodontics, physiology, and, most recently, cardiac surgery. Now, I’m pleased to… …

- One More Time: p Values are Scarily Unreliable - Replicate a study and you are highly likely to get a very different p value. Scarily different. The sampling variability of p values is so great that no p value deserves our trust. Yes, I know, that’s been my mantra for more than a decade, but Steve Lindsay has just… …
- The Diamond Ratio (DR), Our Estimate of Heterogeneity: Accepted for Publication - I’m excited to report that Max Cairns’s PhD work on the Diamond Ratio (DR) has been accepted for publication by the British Journal of Mathematical and Statistical Psychology. The preprint of the final accepted version is here. Our preprint, as accepted by BJMSP The Original DR Blog Post …was in… …

- Open Science: A Detailed Telling of the Story So Far - Concern about publication bias apparently goes back at least as far at Robert Boyle in the 17th century. That’s Barker Bausell’s starting point for his highly detailed account of the replication crisis and rise of Open Science. Bausell, the author of a number of books, brings a broad perspective, across… …

- Cardiac Surgery: Yet One More Research Field Highly Critical of p Values - Replacement heart valves, bypasses, transplants: Cardiac surgery research has given us these life-saving goodies, and more. Now this vital research field has joined many others in appreciating the damage that reliance on p values can bring. Our critical review (here) in the Journal of Cardiac Surgery has just been released… …

- Psychological Inoculation? Prebunking? Assessing the Bad News Game That Targets Fake News - Trying to debunk a conspiracy theory by presenting facts and evidence often doesn’t work ☹ Perhaps prebunking, by giving insight into why fake news can appear credible, might help? To put it another way, psychological inoculation presents a mild form of misinformation, preferably with explanation, in the hope of building… …
- The New APA Style: Try to Contain Your Excitement—and Watch Out for Dud Copies - This is a post for the nerds, fine people that we are. Actually, everyone needs to think about reporting style, especially for statistical stuff. Seventh edition, 2020 Sixth edition, 2010 The APA Publication Manual is the bible of APA Style, also perhaps the bane of some students’ lives. In ITNS… …

- The Myth (?) of the Lucky Golf Ball Lives On, Alas - The APS has just given a kick along to what’s most likely a myth: The Lucky Golf Ball. Alas! Golf.com recently ran a story titled ‘Lucky’ golf items might actually work, according to study. The story told of Tiger Woods sinking a very long putt to send the U.S. Open… …

- What Should We Call Our Estimate of Cohen’s δ: d-unbiased, Hedges’ g, or Something Else? - In ITNS we used ‘dunbiased’ to refer to the debiased estimate of Cohen’s δ, which is Cohen’s standardised effect size in the population. In UTNS I used ‘dunb’. But now ‘Hedges’s g’ seems to be gaining currency as a label for that debiased estimate, despite g having been introduced by… …

The title is: Why Hedges’ gs* based on the non-pooled standard deviation should be reported with Welch’s t-test The issue… …
