it really is astounding that the 80s, 90s and early 2000s were spent on this unrelenting campaign to stop teenagers drinking, having sex and doing drugs but when it finally starts working then millenials and gen X start freaking out about it in a way that is clearly just pure projection. incredible.

When I'm consulting on medical #stats power analyses, MDs always seem to phrase effect sizes as a "percent decrease". For a t-test basically:

(PreTest - PostTest) / (PreTest)

I've never been able to make any use of this for power analyses. Does it have some sort of hidden use I'm not seeing?

Even if you tell people cognitive biases are good & lead to good outcomes, we still think they have the bias less than others.

Only when we see the bias as very desirable we might think we are = to others on it.

We should fear common method variance; especially in self-report scales.

A nonsense likert scale ‘predicts’ later relationship satisfaction.
We are getting results using methods when we are measuring nothing.

Does nature exposure help children with ADHD? In what appears to be the first pre-registered trial, the evidence suggests maybe not. Medication helps but nature exposure has no significant effect.

Hostile and benevolent sexism are both on the decline in 1,097 studies, N = 339,740 since 1996.

Note that "3" on these scales is already a neutral response. Even bigger progress in countries with more hostile sexism.

So we did.
Manipulating people’s belief in free will works, & lasts for somewhere between less than a day to 1 week at best.

Chimpanzees in the wild of Uganda & Cote d’Ivoire have about 1.4 – 2.6 drinks-worth of alcohol per day in over-ripened fruit.

That’s about the same amount per day as modern humans.

Protzko @protzko.bsky.social · 16d

My take on multilevel models based on the literature:

YOU HAVE TO USE MLMS!
Except they have assumptions that are never met.
& when those assumptions aren't met they are biased.
& the 'right' models never converge.
& other approaches are wrong bc they aren't MLMs.
But you have to use them.

I am happy to announce the publication of our new work on the impact of arbitrary analytical choices on type I and type II error rates. We simulated reaction time data in a conflict task and analyzed the notable CSE effect in a multiverse manner. Worrying results:

Preschool-aged kids whose parents are working class are less likely to be called on when they raise their hand compared to kids with middle/upper class occupations.

Say it with me:
Demand effects do not exist in online studies.

Participants in online studies don't care about our research.
They aren't trying to be good subjects.
They want their $.

We also don't see a very sharp difference in the standard deviations in both demand conditions (which we'd expect if we have reacters and compliers). Distributions look pretty similar.
