Grumpy IO psychologist with an interest in research methods, meta-science and personality. Views are my own and not those of my employer. Begrawe my hart op Klein Tambotieboom en strooi my as oor die Bosveld horison
A method that seems designed to allow researchers to draw causal conclusions from single-source, concurrent observational data is a problem. The management literature is awash with this nonsense. Sure, the users are to blame but PROCESS seems almost designed to facilitate this nonsense.

Many journals are members of COPE and their flowcharts and guidelines would supposedly apply but in my experience these are often ignored - sometimes because editors have no idea that their journal is a COPE signatory.

I just wish that grad programs would follow the evidence and not base admissions decisions on personal statements at all - because we have good meta-analytic data showing that they are not predictive of success and because we can't even know who wrote them.

I struggle to think of a statistical "method" that has been more damaging to psychology (and related disciplines) than mediation analysis based on observational data. IMHO all such manuscripts should be desk rejected.

Perhaps I am not following correctly but the authors seem to show that a model with two higher-order factors does not fit data very well and then rely on a model with a single higher-order factor for most other analyses without ever showing (or even testing) that this model exhibits adequate fit.

Horrifying. Of course, many psychologists simple "forget" to even include a control group. In one notable instance that led to about 100 million viewers being misled about the efficacy of power posing.
