Granqvist's "Why Science Needs to Publish Negative Results"

This link is worth it for these pictures alone:

I know, right? Perfect for teaching research methods and explaining the positivity bias in publication.

These figures also sum up the reasoning behind the new journal described in this article. New Negatives in Plant Science was founded in order to combat the file drawer problem. It publishes non-significant research. It is open access. It publishes commentaries. It even plans special issues for specific controversial topics within Plant Science. Which absolutely, positively are NOT my jam. However, the creators of this journal hope that it will serve as a model for other fields. Given the recent flare up in the Replication Crisis (now Replication War?), this new journal provides a model for on-going, peer reviewed, replication and debate.

I think this journal (or the idea behind this journal) could be used in a research methods class as a discussion piece. Specifically, how else could we reduce the file drawer problem? The Open Science Framework offers a new model for transparency in research. Retraction watch provides a highly visible platform for tracking research that makes it through peer review but is later pulled by a journal. What else could we be doing to better vet our research?

Ways to use funny meme scales in your stats classes

Have you ever heard of the theory that there are multiple people worldwide thinking about the same novel thing at the same time? It is the multiple discovery hypothesis of invention . Like, multiple great minds around the world were working on calculus at the same time. Well, I think a bunch of super-duper psychology professors were all thinking about scale memes and pedagogy at the same time. Clearly, this is just as impressive as calculus. Who were some of these great minds? 1) Dr. Molly Metz maintains a curated list of hilarious "How you doing?" scales. 2) Dr. Esther Lindenström posted about using these scales as student check-ins. 3) I was working on a blog post about using such scales to teach the basics of variables. So, I decided to create a post about three ways to use these scales in your stats classes: 1) Teaching the basics of variables. 2) Nominal vs. ordinal scales. 3) Daily check-in with your students. 1. Teach your students the basics...

Using pulse rates to determine the scariest of scary movies

The Science of Scare project, conducted by MoneySuperMarket.com, recorded heart rates in participants watching fifty horror movies to determine the scariest of scary movies. Below is a screenshot of the original variables and data for 12 of the 50 movies provided by MoneySuperMarket.com: https://www.moneysupermarket.com/broadband/features/science-of-scare/ https://www.moneysupermarket.com/broadband/features/science-of-scare/ Here is my version of the data in Excel format . It includes the original data plus four additional columns (so you can run more analyses on the data): -Year of Release -Rotten Tomato rating -Does this movie have a sequel (yes or no)? -Is this movie a sequel (yes or no)? Here are some ways you could use this in class: 1. Correlation : Rotten Tomato rating does not correlate with the overall scare score ( r = 0.13, p = 0.36). 2. Within-subject research design : Baseline, average, and maximum heart rates are reported for each film. 3. ...

Rouse, Russel, & Campbell (2025) is a curated list of Psi Chi journals that are perfect for Intro Stats.

This summer, the Psi Chi Journal of Psychology Research published Rouse, Russel, and Campbell's Beyond the textbook: Psi Chi Journal articles in introductory psychology courses. It is a curated list of paywall-free Psi Chi articles, mostly with student co-authors, that are peer-reviewed and of an appropriate writing level and length to use in an Introduction to Psychology course. The authors provide the following information for each of the articles: In addition to being appropriate for Into Psych, these articles are also perfect for Intro Stats. In my classes, I emphasize the ability to read and write simple result sections. One way I would review this skill is by showing my students Results sections from published research and asking them to identify the test statistics, effect size, and other relevant information. This selection of articles features clear and concise results sections for t -tests, ANOVA, factorial ANOVA, regression, and correlation. I created a spreadsheet...
