Rethinking 'WEIRD': It's Time for a Change If we want to reduce Western bias in psychology, we should stop labeling people as WEIRD or non-WEIRD.

Causal inference for psychologists who think that causal inference is not for them Correlation does not imply causation and psychologists' causal inference training often focuses on the conclusion that therefore experiments are needed—without much consideration for the causal infer...

You need to bring in the same toolkit as in studies that try to establish causality without randomization.

I know it sounds unfair, but I don’t make the rules. These situations are instances of post-treatment bias, if you want to read up on it as a psychologist:

Lots to say on this, but one thing recently came to my mind is the isomorphism between “wide format” & “long format” for panel datasets. The latter treats time as a variable, which confuses the issue, at least conceptually. DiD with wide format is clear and here: journals.sagepub.com/doi/10.1177/...

Gain Scores Revisited: A Graphical Models Perspective - Yongnam Kim, Peter M. Steiner, 2021 For misguided reasons, social scientists have long been reluctant to use gain scores for estimating causal effects. This article develops graphical models and g...

See Kim & Steiner journals.sagepub.com/doi/10.1177/... The design for difference in differences is a quasi experimental design, the noneqivalent control group design. Judd and I in 1981 in Estimating the Effects of Social Interventions have a very similar path diagram.

The Big 5 test is about twice as accurate as the Meyers-Briggs Type Indicator for predicting life outcomes, placing the usefulness of the MBTI test halfway between science and astrology.

Any psychologist will tell you, the Meyers-Briggs is mostly bullshit.

In 2015 the Open Science Collaboration (OSC) (Nosek et al 2015) published a highly influential paper which claimed that a large fraction of published results in the psychological sciences were not reproducible. In this article we review this claim from several points of view. We first offer an extended analysis of the methods used in that study. We show that the OSC methodology induces a bias that is able by itself to explain the discrepancy between the OSC estimates of reproducibility and other more optimistic estimates made by similar studies. The article also offers a more general literature review and discussion of reproducibility in experimental science. We argue, for both scientific and ethical reasons, that a considered balance of false positive and false negative rates is preferable to a single-minded concentration on false positive rates alone.

Overestimated effect sizes and underestimated power explain the Open Science Collaboration's (2015) low reproducibility rates.

Favoring parsimonity isn't really a good approach when it comes to confounder control -- *not* including a variable usually entails stronger assumptions, so keeping the model "lightweight" implies a lot of additional assumptions.

One approach to the age-period-cohort problem: Just don’t. Just to cause yourself more problems, you seek for something. But there is no need for you to seek anything. You have plenty, and you have just enough problems. Shunryū Suzuki in a 1971 talk A ...

New blog post about the age-period-cohort identification problem!

In which, for the first time ever, I ask "What's the mechanism?" and also suggest that sometimes you may actually *not* be interested in causal inference.

Sometimes a causal effect is just a causal effect (regardless of how it’s mediated or moderated) TL;DR: Tell your students about the potential outcomes framework. It will have (heterogeneous) causal effects on their understanding of causality (mediated through unknown pathways), I promise. It’...

To talk about something causally affecting something else, it doesn’t matter whether it’s sufficient or necessary. It also doesn’t matter if there are mediating mechanisms — technically, everything in the social sciences needs to be mediated somehow!

Thanks, Glad you Like it! It also Shows that you nees a Lot of Stimuli in Order to get reliable assessments

Sure, but the logic underlying the DK claim is that If you are intelligent you have an easier time spotting intelligence. I can See no reason why this logic should only apply to self judgements. But typical alternative explanations Like Regression to the mean don't apply here

8/9 Low loadings mean low reliability, and low reliability means summary measure correlations are attenuated by measurement error. But! Our models account for this, and model 2 reveals a latent correlation of r = .82. Model comparison adds to the story, altogether ruling out r = 0 and r =1

The Kruger Dunning study examines whether highly capable people are more self aware of their OWN capabilities. Your study looks at the ability to detect ability in OTHERS.

Super paper. Serves as a model for how to measure individual differences in social accuracy. Congratulations!

New paper out:
Some people are systematically better at judging others’ intelligence.
Who are the best judges? People WHO are intelligent themselves, have good emotion-perception ability, and who are high in well-being.
