A randomized controlled trial by Team Scientist Eugenia South and collaborators tested whether street cleaning reduces gun violence in Philadelphia.
Cleanups reduced visible litter, but did not significantly reduce gun violence or serious crime.
The authors suggest that more comprehensive place-based prevention strategies are likely needed.

In a @JAMANetworkOpen commentary, Team Scientist Mitesh Patel and Joshua Liao argue that health systems should align patient outreach with how people actually communicate today—mobile and asynchronous.
They point to a colorectal cancer screening trial in which text-message nudges outperformed nurse phone calls and boosted at-home test completion from 49% to 59%.

A new @Nature paper co-led by Team Scientist @szaszibarnabas had 457 researchers reanalyze 100 social and behavioral science studies. Most reanalyses reached the original conclusion — but reanalysts fully agreed with each other on only 34% of studies.

Large language models display a "parahuman" susceptibility to classic persuasion techniques.
A new @PNASNews paper by Co-Director @angeladuckw, team Scientists Dr. @RobertCialdini & Christophe Van den Bulte, and collaborators finds that across 126,000 conversations, persuasion principles increased LLM compliance with objectionable requests.

A megastudy by Team Scientist @jgvoelkel and collaborators tested 12 brief digital mental health programs in 7,505 adults with depression. Nearly all improved how people felt immediately, and 2 significantly reduced depression a month later.

New research by Team Scientist @ayeletfishbach and collaborators finds that giving to fewer people, rather than more, signals stronger social connection to each recipient, and makes gifts more valued and more likely to be reciprocated.

Research in @ScienceMagazine by Team Scientist @DG_Rand and collaborators found that Large Language Models are more persuasive when they pack their replies with facts.
However, LLMs optimized for persuasion were less accurate — generating more claims, but fewer reliable ones.
