  • Statisticians see the light–Hooray! - "Scientific Method for the Twenty-First Century: A World Beyond p
  • Open Science and The New Statistics: Be Happy! - In May this year at the APS Convention in Boston, Bob and I ran a symposium with the title From NHST to The New Statistics: How do We Get There? It was great fun. There is a summary here. Next year the APS Convention will be in San Francisco in
  • Video – Getting started with the New Statistics and Open Science - This fall I (Bob) was invited to give a talk at Indiana University as part of a series on good science and statistical practice organized by the university's Social Science Research Commons (SSRC).  The SSRC is like a core facility for getting advice on statistics and experimental design...what a cool
  • ITNS at SfN17 in DC - As Bob mentioned in his post earlier today, he's at SfN17, the enormous (30,000+ folks) Neuroscience meeting happening now in Washington DC. Here's how the SfN site describes the meeting: "SfN’s 47th annual meeting, Neuroscience 2017, is the world’s largest neuroscience conference for scientists and physicians devoted to understanding the
  • The New Statistics for Neuroscientists - This summer I (Bob) was asked to write a series of perspective pieces on statistical issues for the Journal of Undergraduate Neuroscience. My first effort has just been published (Calin-Jageman, 2017)--it is a call for neuroscience education to shift away from p values, and an explanation of the basic principles
  • Improving Psychological Science: The Latest From SIPS - You may recall that SIPS is the Society for the Improvement of Psychological Science. My colleague Fiona Fidler recently reported that the second SIPS conference was "probably the best conference I’ve ever been to". When I met her the other day she was still enthusing about that meeting, and the
  • The ASA Symposium on Statistical Inference: Bob’s great talk - "A world beyond p < .05." That's the subtitle for the ASA Symposium on Statistical Inference, which ran last month. Bob was there and recently posted a brief initial report. I wasn't there, alas, but I've now had three independent reports that Bob's talk at the Symposium was fantastic. I'm
  • Replication: ‘Psychological Science’ does the right thing - I have been enjoying Bob's series of posts about replication. (Go to our home page and scroll down to see links and a few lines of text about each of the 5 posts, with title starting 'Adventures in Replication'.) Actually, "enjoying" isn't quite the right word. "Appreciating", perhaps, and "sharing
  • Adventures in Replication – Reviewers don’t want to believe disappointing replication results - Trying to publish replication results is difficult.  Even when the original evidence is very weak or uncertain, reviewers tend to look for reasons to explain away a smaller effect in the replication.  If nothing comes to mind, reviewers may even make something up.  Here's an actual review I received: Depending
  • Beyond p values – Dispatches from the ASA symposium on statistical inference - The next couple of posts will be about my experience at the ASA conference on statistical inference: A World Beyond p < .05. The first session featured Steve Goodman and John Ioannidis (who Skyped in from Australia).  One highlight was Goodman's explanation of why p values continue to be so
  • Brain Stimulation – Can we trust the empirical record? - Brain stimulation research has been exploding in neuroscience.  First came the rapid adoption of Transcranial Magnetic Stimulation (TMS), a technique in which powerful magnetic fields are used to create inductive currents within the skull.  More recently, Direct Current Stimulation (DCS) has burst onto the scene, a technique where current is
  • Enthusiasm for teaching and learning - It's a joy to be with faculty who are deeply enthusiastic about teaching and about student learning. I'm just back from AusPLAT (Australian Psychology Learning and Teaching), the first Australian conference on learning and teaching, under the auspices of the Australian Psychological Society. Only about 60-70 folks participated, but the
  • Adventures in Replication: p values and Illusions of Incompatibility - Here's an idea I run into a lot in peer reviews of replication studies: If the original study found p < .05 but the replication found p > .05, then the results are incompatible and additional research is needed to explain the difference. Poor p values.  I'm sure they want
  • Something a bit different: maintaining memories - I'm wondering off the topic of the New Statistics today just to mention that my lab has published a new paper that characterizes the the changes in gene expression that accompany storing and maintaining a new long-term memory  (Conte et al., 2017) .  This is my main research passion, and
  • Adventures in Replication: Your replication appears to be somewhat underpowered - Many journals now proclaim their openness to replication research.  Behind the scenes, though, replication manuscripts are often met with impossible demands and/or insane double-standards. Here's an example from an editor at a prominent social psychology journal: the studies appear to be somewhat underpowered. This is (as reviewer 1 notes) because
  • The joy of many disciplines - One of the great things about working in psychology, or statistics, or--just imagine!-- both, is that you can get to play in the backyards of many other folks. As science becomes more and more fragmented, and many researchers feel that their best strategy is to aim for expertise in some
  • Adventures in Replication: Scientific journals are not scientific - The essence of science is seeking and weighing evidence on both sides of a proposition.  One might think, then, that when a scientific journal publishes a research paper it then acquires a special interest in publishing subsequent replications or commentary on that topic.   We might call this the "principle of
  • Adventures in Replication: Introduction - Over the past 5 years or so, I (Bob) have been a bit replication crazy--I've conducted about 10 direct replication projects in collaboration with undergraduate students at Dominican.  I became obsessed in part because I wanted to know for myself if the alarm bells being raised during the 'replication crisis'
  • Red, Romance, and Replication - I have a new replication paper out today, a collaboration with DU student Elle Lehmann (Lehmann & Calin-Jageman, 2017) .  The OSF page for the paper with all the materials and data is here: https://osf.io/j3fyq/ (Calin-Jageman & Lehmann, 2015) The paper replicates a set of previous findings showing that the
  • “The best conference…”: More about SIPS - Here's more about the recent SIPS Conference, from my colleague Fiona Fidler who was clever enough to be there. (Some background: Fiona, of The University of Melbourne, is among other things a psychologist, ecologist, and historian of science. Her PhD thesis, From statistical significance to effect estimation: Statistical reform in
