When science gets misrepresented, trust in science goes down. Good for @jespinosa.bsky.social to call out #misinformation, esp. given how contentious this topic is!

You know what our recent paper on early life adversity and #dog #behaviour DOESN'T say? Anything about pit-bull type dogs. No mention by us at all, @sciencex.bsky.social. So... how did they earn a callout for aggression and fear in your piece? phys.org/news/2025-10... 1/idk, as many as it takes 🧪
Trauma in a puppy's first six months linked to adult aggression, says new study
As many dog owners can attest, their four-legged companions are delightful and loving. But for others, their animals have an aggressive side, such as biting and attacking strangers, which may ultimate...

📣 New publication alert! In a large, diverse sample, #CompanionDogs with a history of trauma before 6 months were seen as more fearful and/or aggressive than trauma-free dogs or those with trauma later on in life

Our paper “The Reasonable, the Rational, and the Good” is finally out in Open Mind 🎉It spent over a year under review at another place—positive reviews + R&R—before getting rejected. Publishing is slow & messy. If you’re going through it, you’re not alone. direct.mit.edu/opmi/article...
The Reasonable, the Rational, and the Good: On Folk Theories of Deliberative Judgment
Abstract. Judgment is often described in terms of an intuitive (System 1) versus deliberative (System 2) dichotomy, yet sound deliberation itself can take more than one form. Building on philosophical...

6/ Takeaway:
Adversity ≠ guaranteed growth.
But distancing in tough times can help.
And complex thought is not merely a dispositional trait you have: it’s a process you do.

5/ Our companion ERSP review shows why the field got stuck: Too many studies confuse between-person differences (“wise vs. less wise”) with within-person change (“how to become wiser”). www.tandfonline.com/doi/abs/10.1...
Classic ecological fallacy.
igi.bsky.social
4/ Instead: Wisdom = a dynamic network of #intellectualhumility, #perspective-taking, #compromise, & recognition of #change.
It ebbs and flows with context.

3/ Why does this matter for psychology?
Because we also tested 3 core assumptions about development of complex thought:
❌ Not a single trait
❌ Not cross-situationally stable
❌ Not the same between vs. within people
#PsychScience

2/ We now decided to use more mature dynamic modelling systems to look at factors that may promote #within-person #growth What did predict wiser reasoning months later?
👉 Self-distancing: stepping back, taking an outsider’s view.
Not social support. Not “finding meaning.”

1/ Many theories promise “post-traumatic growth.”
But in a year-long study our group did, adversity alone did not boost wisdom; there were no automatic gains. journals.sagepub.com/doi/abs/10.1...

9/10 Bottom line: we value social knowledge without always wanting explicit advice. Collective intelligence is powerful, but appear biased to favor private deliberation.
igi.bsky.social
8/10 Cross-checks: Effects replicate when strategies aren’t framed as exclusive, and in small-scale societies using oral interviews.
igi.bsky.social
7/10 #Independence vs #interdependence calibrate (but don’t reverse) the pattern. Even in more interdependent contexts, self-reliant choices dominate. Likely reasons: autonomy feels rewarding; private evidence is more vivid; advice can carry reputational costs/obligations.
igi.bsky.social
6/10 Expectations diverge: many think their compatriots will ask friends; personally, they still opt for self-reliance!
igi.bsky.social
5/10 ‘Wisdom of crowds’ is least preferred. Friends’ advice is more preferrable, but on average still behind deciding on one’s own.
igi.bsky.social
4/10 Result: self-reliance is the modal preference. People mostly pick private deliberation (often #1) or intuition. Advice-oriented routes trail.
