Resources

Here you can find a collection of things that may be helpful, including slide decks, a curated list of introductory papers and blog posts, as well as some infographics I have generated to explain various things.

Slides

Slides for more talks I have given can be found on the Open Science Framework in my Quick Files project here.

Introductory papers

I have written several papers to introduce researchers from psychology (and other fields) to causal inference. Here are some that may be useful if you are new to the topic:

Blog posts

The 100% CI is a blog that I run together with three friends of mine, Anne Scheel, Ruben Arslan, and Malte Elson. Here are a couple of posts that may be helpful:

Infographics

When I gave lectures or talks, I used to struggle with explaining how randomized experiments can actually work. I thus generated a small infographic (link to just the figure) that uses the potential outcomes notation and illustrates how in a randomized experiment the difference in the average outcome between the two groups identifies the average of the individual-level causal effects.

If you want to re-use or adapt this, you can download a ZIP file that contains all the materials here. This contains the underlying R-code, the individual panels, and the PowerPoint file in which I brought it all together.

Another thing I occassionally have to explain is how estimates of interactions may be confounded – and how appropriate statistical control requires the confounder to be interacted with the treatment of interest. I made another illustration to drive home this point, here’s a link to just the figure.

Here’s the ZIP file containing containing the materials (R-code, individual panels, PowerPoint file to bring it all together): Figure Interactions.zip.

And here’s a figure illustrating different ways to include age (or other predictors) in a model with varying degrees of flexibility. Here’s a link to just the figure and you can download all materials necessary to reproduce it (R-code to generate individual panels, PowerPoint file bringing it all together) here.
