Abstract. Argument mapping is the practice of diagraming the logical relationships between each proposition in an argument, including objections and counter-objections. Some studies find that courses that teach students how to map arguments exhibit better critical thinking and persuasive writing than students in other courses. These promising results are sometimes from surveyors of argument mapping goods and services, and they garner plenty of attention in fields that champion careful thinking and communication. However, the total evidence is mixed, null results are often never published, and many promising studies have not controlled for known confounds. Two waitlist control trials (N = 83) attempted to address t

Reducing Existential Risk By Reducing The Allure Of Unwarranted Antibiotics: Two low-cost interventions

Nick Byrd & Olivia Parlow

Over one million annual deaths have been attributed to bacterial antimicrobial resistance. Although antibiotics have saved countless other lives, overuse and misuse of antibiotics increases this global threat. Developing new antibiotics and retraining clinicians can be undermined by patients who pressure clinicians to prescribe unnecessary antibiotics. So we validated two low-cost, scalable interventions for improving antibiotic decisions in an online randomized control trial and a pre-registered replication (N = 985). Both first-person vignette experiments found that an infographic and text message caused intermediate to large improvements in antibiotic decisions compared to active controls — even when controlling for a dozen confounds. Notably, these educational interventions also reduced trust in a clinician who offered [the unnecessary] antibiotics.

"The 2025 IAPHS Annual Meeting theme will be 'Community Engagement in Population Health Science' in recognition that solutions to health inequities and our greatest population health challenges aren’t found in the lab or a dataset, but rather within communities themselves. Pairing scientific and lived experience, and the cocreation of evidence for action, will drive the agenda. Planned plenaries will focus on methods, funding, and translation to policy to ensure all communities have a genuine opportunity to thrive."

The Nudges in Health Care Symposium is an annual event organized by the Penn Medicine Nudge Unit since 2018. The goals of this event are to:

- Assemble individuals from health organizations interested in applying behavioral science or forming nudge units
- Share insights on lessons learned from implementing nudges in health care
- Network and build collaborations across the health care sector

The next symposium will take place September 11–12, 2025, in Philadelphia.

How can #BehSci combat #antimicrobialResistance?

Many patients expect needless #antibiotics (https://doi.org/10.3201/eid2012.140331), which #nudges clinicians to prescribe 'em (https://pubmed.ncbi.nlm.nih.gov/28206788).

So we validated nudges to improve patient expectations (N ≅ 1k): https://osf.io/preprints/psyarxiv/d2pc4_v1

A slide asking how we can nudge patients to improve their understanding, expectations, intentions, and decisions regarding unnecessary antibiotics.

Experimental design: randomize to nudge or control infographic before initial questionnaire (e.g., about expectations) and then randomize to a nudge or control text message before the final questionnaire (e.g., about whether to ask for antibiotics, try over-the-counter meds instead, etc.).

Potentially bad news for a common practice of wait-and-see antibiotic prescriptions (in which clinician writes the prescription, but asks the patient not to full it unless certain diagnostic symptom patterns occur in the next few days): this mere OFFER of antibiotics may actually INCREASE interest in antibiotics (rather than the reverse).

Both nudges improved people's expectations, intentions, and decisions regarding unnecessary antibiotics — effects that replicated in a high-powered, pre-registered replication.

6 Types of Nudges Can Affect Your Choices

https://www.psychologytoday.com/us/blog/stretching-theory/202406/6-types-of-nudges-can-affect-your-choices

"New research offers a helpful framework for categorising different types of nudges. Categories are based on six distinct cognitive mechanisms, through which a nudge might influence behaviour: (1) attention, (2) perception, (3) memory, (4) effort, (5) intrinsic motivation and (6) extrinsic motivation." -- #Eva_M_Krockow

The #Monopoly experiment on #inequality was conducted in 2006, 10 years before the archetype of entitled cheating power-grabber #Trump got elected. The experiment shows how winners of a rigged game lose empathy & start believing in their own merit. The media extensively covered this experiment at the time; yet the #USA still blasted through, producing more egotistic maniacs like #ElonMusk. #Psy #nudges of #community #compassion do change this dynamic: this work is URGENT🚨 https://www.youtube.com/watch?v=bJ8Kq1wucsk&list=PLOGi5-fAu8bGgZFDYGhQ6uywa5GNeA2RT

Nudging - a behavioral economics developed technique for ensuring compliance and solidifying target engagement. Getting tired of the constant text messages and emails? You’re being #Nudged in a calculated manner. The scientists have developed a comms model using digital tools to ensure you make that doc’s appointment, or don’t miss that sale. I’ll be posting more about this irritating trend in future toots. Stay tuned. #Nudge #Nudges #BehaviorialEconomics #compliance #ComplianceEngineering

Good read for #BehavioralScience / #BehaviourChange folks...

To me, it is a welcome addition to the idea that, on its own, #BeSci can't save the world. #Nudges are fine but need to be in their right context.

This means balancing then against other levers of change, eg policy, legislation, restrictions etc.
