Reflexivity in quantitative research: A rationale and beginner's guide
Reflexivity is the act of examining one's own assumption, belief, and judgement systems, and thinking carefully and critically about how these influence the research process. The practice of reflexiv...

New blog post! Three reasons why (some) idiographic studies in psych leave me unimpressed: (1) failure to establish that there's meaningful variation, (2) imprecise estimates at the individual level, (3) the usual estimand confusion (is it causal? yes/no/maybe a bit?).

Idiographic Approaches in Psychology: Hold your horses
There have been persistent calls spurring psychologists to do more “idiographic” research, starting even before Peter Molenaar’s “Manifesto on Psychology as Idiographic Science”, which is already 20 y...

I have a joke about experimental social psychology, but it doesn’t work if you repeat it.
I have a joke about scientific publishing, but I need to run it past my peers first.
I have a joke about affordable housing, but most of you wouldn't get it.

The main reasoning seems to go like so:
1. A lack of fit of a 1d measurement model indicates that the items do not have exactly 1 common cause.
2. If there is more than 1 common cause, then, e.g., Cronbach's alpha does not measure the correlation between the outcome and the target of measurement.

I advocate for critical thinking about what “SES” is supposed to represent. Social theory & quantitative sociology provide good ways of doing this before selecting variables. Is it social status, ie. prestige you want to measure? Or social class? Deprivation? Each have different measures
Hey #EpiSky, ever wanted to learn more about measuring Socioeconomic Status (SES)? #SER has a playlist for that! To learn more:

They've published 23K papers in 2024 with APC of £2090, raising £48 million from this journal alone, so should be able to put resource into cleaning this up.

Hard to publish null results, academic prizes (e.g. Nobel) only for the spectacular results, late breaking sessions on science congresses for surprising findings with impact, … and we keep being surprised when hear news about scientists exaggerating results and fake their data

Today is World Mental Health Day, and the theme this year is Mental Health At Work.
So it's a good time to share this study (N = 46,336), which suggests that individual-level MH interventions at work are not effective at improving wellbeing

New preprint! There are lots of interesting estimators that can be used to target causal effects, some of which aren't well-known in psychology. Arthur Chatton and I provide a (gentle) introduction to approaches commonly used in epidemiology: psyarxiv.com/k2gzp
