In new work, we find 50% of high profile social media papers are connected to big tech through funding, collaboration and employment. Most connections aren't disclosed. @jbakcoleman.bsky.social @jevinwest.bsky.social @carlbergstrom.com 1

The Development of Morality and Conventionality Across Cultures: Implementing a Two‐Stage Model for Cross‐Cultural Research Establishing a shared sense of right and wrong is an essential milestone for human cooperation, raising the question of whether a universal set of moral intuitions exists. However, tests of universa.....

A common problem w/ studies testing non-WEIRD groups is they compare multiple groups using the same WEIRD measure. How can we compare groups w/ apples-apples measures w/o distorting cross-cultural differences? We explore this in this new paper! onlinelibrary.wiley.com/doi/10.1111/...

Holy shit. This guy saved a PNG to a bird.

(he drew a bird into a spectrogram, played that sound to a starling, and the starling reproduced it back to him with enough accuracy he got his bird drawing back in their call's spectrogram) www.youtube.com/watch?v=hCQC...

Across six societies children engage in costly third-party punishment of unfair sharing - Communications Psychology Third-party punishment of unfair sharing is a hallmark of a normative concern for fairness in adults. Here, children in Canada, India, Peru, Uganda, USA, and Vanuatu show this same normative concern b...

Overparenting is on the rise and hurts children’s motivation starting in early childhood. How can we help parents step back? Our new paper in Child Dev shows that pointing out learning opportunities reduces overparenting.

New paper with @ktvasq.bsky.social, Emily Gerdin, @yarrowdunham.bsky.social, and @zoeliberman.bsky.social in JEP: General:

"Expectations of intergroup empathy bias emerge by early childhood"

Meltem Yucel (@drmeltemyucel.bsky.social) just won SPSPs Emerging Scholar award!

Recently, she found that young children (between ~4 & ~8) do not perceive distributional fairness as a moral norm. Nor is it obviously conventional.

Need more convincing that ASFP is worth YOUR time? Dr @yarrowdunham.bsky.social thinks it is - read what he has to share below!

I like this thought! Obviously in some cases it is all just numbers somewhere, but things like property definitely have a different feel...

we didn't present any idea or argument but in one version we did say something like: The parents have $x in assets and $x in debts, how much of each should go to the children? Despite knowing how it would really work most still endorsed getting all assets and no debts!

In some cases this seems right. In terms of our effect we've wondered about this in a sort of identifiable victim sense, like, who cares if the bank loses out but for a specific to lose out...
But in other cases not repaying a debt IS inflicting a loss on someone else.

totally, though someone is presumably getting harmed when you don't pay your debts...
