Always remember:
There are no effects without causality
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.

🧠🌍 Big Team Science aims to make global science thrive. But what happens when collaborators come from countries in conflict? Or when researchers are unwilling, unable, or legally barred from working together?

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.

Don't let minor submission errors delay the publication of your research! 📝 🔬
Remember to check the full guidelines when submitting the manuscript to PsyArXiv (buff.ly/M3cRBW2).
Below, we also have a few friendly reminders!
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.

"Credible science, evaluating science, & need for a science reform"
Amazing they have an open-science "Defense Against the Dark Arts" course, and that they invited me to give a session.

Public appreciation post for @juliabottesini.com! The community doesn't know the great lengths Julia has gone to restabilize operations at PsyArXiv. We're all incredibly lucky to have her. Many, many hours and a great deal of thought/care have gone into the task. Thank you, Julia!

We have to start finding out how long our interventions last.
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.

Lol.
Never changes
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:

Academia.edu is changing its Terms and Conditions, and they're so outrageous (AI training; signing over ownership to them etc) I closed my account today.
A thread with some practical tips if you want to delete your account (5 steps):
Proposal for how to fix family wise error rates.
For every uncorrected p value you must add an extra letter to the claim.
“Eating chocolate maaaaaaaaay be associated with lower rates of stroke”
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.
Early socialization indeed.

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 $.

Researchers: Stop Thinking You Know How Things Have Changed, Go Measure It!
Your intuitions are biased.
The past isn't how you think it is.
Measurement Invariance is a mindset & a must.

There is a growing inequality in reading for pleasure.
Those who read are reading for longer now than 20 years ago.
BUT when asking people what they did in the past 24 hours fewer said they read (28% to 16%).
