  • NeuRA Ahead of the Open Science Curve - I had great fun yesterday visiting NeuRA (Neuroscience Research Australia), a large research institute in Sydney. I was hosted by Simon Gandevia, Deputy Director, who has been a long-time proponent of Open Science and The New Statistics. Neura's Research Quality page describes the quality goals they have adopted, at the initiative…
  • I Join an RCT: A View From the Other Side - In ITNS we discuss randomized control trials (RCTs) and I've taught about them since whenever. If done well, they should provide gold standard evidence about the benefits and harms of a therapy. So I was particularly interested to be invited to join a large RCT. My wife, Lindy, and I…
  • Replications: How Should We Analyze the Results? - Does This Effect Replicate? It seems almost irresistible to think in terms of such a dichotomous question! We seem to crave an 'it-did' or 'it-didn't' answer! However, rarely if ever is a bald yes-no decision the most informative way to think about replication. One of the first large studies in…
  • ‘Preregistration’ or ‘Registration’? - For years, medicine has urged the 'registration' of clinical trials before data collection starts. More recently, psychology has come to use the term 'preregistration' for this vital component of Open Science. The 'pre' puts it in your face that it happens at the start, but should we fall into line…
  • Congratulations Professor Fiona Fidler! - Just as the fabulous AIMOS Conference -- one of Fiona's most recent triumphs -- was wrapping, it was announced officially that Fiona Fidler has been appointed as full PROFESSOR at the University of Melbourne. Wonderful news! Wow, when Simine Vazire arrives at the University of Melbourne next year, also as…
  • AIMOS — The New Interdisciplinary Meta-Research and Open Science Association - Association for Interdisciplinary Meta-Research & Open Science (AIMOS) I had a fascinating two days down at the University of Melbourne last week for the first AIMOS conference. The program is here and you can click through to see details of the sessions. Congratulations to Fiona Fidler and her team for…
  • Good Science Requires Unceasing Explanation and Advocacy - Recently in Australia a proposal was made for an “independent science quality assurance agency”. Justification for the proposal made specific reference to "the replication crisis" in science. Surely we can all support a call for quality assurance in science? Not so fast! First, some context. Australia's Great Barrier Reef, one…
  • Open Statistics Conference – Talk and Resources - I had the great pleasure today of discussing the estimation approach (New Statistics) at the Open Statistics / Open Eyes conference in Cesena, University of Bologna. Here I'm posting some resources for those looking to get started with the New Statistics: Here's our "Getting Started" page with links to textbooks,…
  • Registered Reports: Conjuring Up a Dangerous Experiment - Last week I (Bob) had my first Registered Report proposal accepted at eNeuro. It's another collaboration with my wife, Irina, where we will test two popular models of forgetting. The proposal, pre-registration, analysis script, and preliminary data are all on the OSF: https://osf.io/z2uck/. Contrary to popular practice, we developed our…
  • Transparency of reporting sort of saves the day… - I'm in the midst of an unhappy experience serving as a peer reviewer. The situation is still evolving but I thought I'd put up a short post describing (in general terms) what's happened because I'd be happy to have some advice/input/reactions. Oh yeah, this is a post by Bob (not…
  • Meta-Science: It’s all Happening in Melbourne - Are you interested in meta-science? In Open Science? If so, check out the inaugural conference of AIMOS, the Association for Interdisciplinary Research &Open Science. It's a two-day meeting, on 7 & 8 November, at the University of Melbourne. There's an impressive list of confirmed speakers: Click here and scroll down.…
  • eNeuro’s new push to encourage estimation - eNeuro, one of the two journals published by the Society for Neuroscience, has revised its author guidelines to encourage estimation. That's great news. Here is: The announcement and comment from editor Christophe BernardAn accompanying commentary from us that explains estimation using neuroscience examples and provides concrete examples of how it…
  • ‘Open Statistics’: It’s All Happening in Italy - I knew good things were happening at the University of Bologna this (northern) summer. Now I know the details. The brochure is here, and this is part of the title page: What do they mean by 'Open Statistics'? As I understand it, they will be discussing statistical methods needed in…
  • The New Statistics Videos: 5 Years On - This week's news email from the APS includes this interesting item: Aha, I thought, they are giving publicity to Tamara and Bob's wonderful workshop at the APS Convention last month. Great! But the link didn't go to the materials for that workshop (which you can find here--well worth a look).…
  • To Understand (or Teach) CIs, Adopt an Estimation Mindset - Update 8 June. Some minor tweaks. Addition of the full reference for two papers mentioned. Of course I would say that, wouldn't I?! It's the basis of ITNS and a new-statistics approach. But the latest issue of SERJ adds a little evidence that, maybe, supports my statement above. The article…
  • Do People Have a Binary Bias? - For years I've been working on changing my thinking--even when just musing about nothing in particular--from "I wonder whether..." to "I wonder to what extent...". It has taken a while, but now I usually do find myself thinking in terms of "How big is the effect of...?" rather than "Is…
  • A Promising Textbook? I Don’t Think So - Updated 30 May 2019. A few tweaks to the text below. I have now had a chance to have a squiz at the book itself. Bob has also seen the book and given a quick opinion. I am confirmed in my view below that, alas, the book is not a…
  • The Cookie-Monster Study: The highly influential memory of a long-lost study - In psychology, there are a few studies so famous and influential that they have proper names: The Good Samaritan Study, the Asch Obedience Study, the Marshmallow test, etc, etc. Approaching this echelon is the "Cookie Monster Study", an increasingly-famous study of social power. If you don't already know it, here's…
  • Reply to Lakens: The correctly-used p value needs an effect size and CI - Updated 5/21: fixed a typo, added a section on when p > .05 demonstrates a negligible effect, and added a figure at the end. Daniel Lakens recently posted a pre-print with a rousing defense of the much-maligned p-value: In essence, the problems we have with how p-values are used is human…
  • The TAS Articles: Geoff’s Take - Yay!  I salute the editors and everyone else who toiled for more than a year to create this wonderful collection of TAS articles. Yes, let’s move to a “post p<.05 world” as quickly as we can. Much to applaud  Numerous good practices are identified in multiple articles. For example: Recognise…
