✈️ Die Koalitionsspitzen wollen die Flugsteuer senken – und gleichzeitig wird das Deutschlandticket teurer. Statt Billigflüge zu subventionieren, sollten sie lieber in die marode Bahn investieren und für günstige Zugtickets sorgen. Jetzt Appell unterzeichnen ➡️ aktion.campact.de/s/flugsteuer...

NL funder NWO recently changed rules for grant applications to endorse more modern recognition & reward practices.

But in my reading, the updated preproposal rules (CV, output, & just the slightest teensy weensy hint of a research idea) fully lean into Matthew effect.

Thoughts?

Come work with us!
There are 3 Oxford-based post doc positions for this Wellcome Trust project that will be advertised soon!

If you have experinece in neurostimulation (tms/tus) and/or modelling of cogneuro data in humans do contact one of us (me, @mkflugge.bsky.social @lilweb.bsky.social, Jacinta OShea) to discuss!
Repetitive negative thoughts will be investigated using a range of cutting-edge brain science techniques as part of a new study led by the Department of Psychiatry, University of Oxford and funded by Wellcome @wellcometrust.bsky.social 👇

New work with @simyciri.bsky.social. Adults make more accurate decisions than adolescents—yet show more intrusion from irrelevant players. We explain this paradox via efficient information compression: adults rely on combinatorial social basis functions that use group structure as a mental scaffold.
🥳!!NEW PREPRINT!!🥳

We show that the tendency to compress complex social information into priors about social structures becomes more pronounced during adolescence.

Much-needed data on lottery-based funding! #SNF

Our current system wastes resources (~40 days for applicants, ~10 days for reviewers for ~85% rejection).

It selects great grant writers, not necessarily great projects, with strong biases against minorities.

“data show an increase of 10% in submissions & 23% in funded projects from female applicants with the lottery-first approach compared to a previously used procedure. Additionally, the lottery-first approach was estimated to have 68% lower economic costs compared to single-stage peer review approach”

Initial Expectations and Confidence Affect the Formation of Novel Self—Beliefs and Their Revision
AbstractHuman self-beliefs hinge on social feedback, but their formation and revision are not solely based on new information. Biases during learning, such as confirming initial expectations, can lead to inaccurate beliefs. This study uses computational modeling to explore how initial expectations about one’s own and others’ abilities and confidence in these beliefs affect processes of belief formation and belief revision in novel behavioral domains. In the first session, participants formed performance beliefs through trial-by-trial feedback. In the second session, feedback contingencies were reversed to promote a revision of beliefs. Results showed that people form and revise beliefs in a confirmatory manner, with lower initial expectations being linked to more negatively biased belief formation and revision, while growing confidence strengthened these beliefs over time. Once formed, these beliefs proved resistant to change even when faced with contradictory feedback. The findings suggest that newly formed beliefs become entrenched and resistant to new, contradictory information in a short period of time. Understanding how self-beliefs are formed, the role that confidence plays in this process, and why established beliefs are difficult to revise can inform the development of interventions aimed at promoting more adaptive learning in educational, clinical, and social contexts.

Preprint!

Led by Jan F Weis, we show that self-compassion predicts positive affect and self-esteem, & protects self-esteem in low performers. Also, positive affect reflects reward expectations & prediction errors, and regret, but independently from self-compassion.

We not only need to rethink the publication and impact factor-based system (see doi.org/10.1098/rsos...), but also the way and approaches #researchfunding is distributed in academia.

(Vicarious) Paper Alert for @finnluebber.bsky.social et al.

Funding schemes that run a lottery to select scientists for submission of full grant proposals can counteract gender bias and reduce societal monetary costs of research funding. Check it out:
