🧵 Thread: Does the internet threaten democracy? I argue that it does in my latest piece in Science: doi.org/10.1126/scie... Here's the short version. 1/9 1/10
doi.org
The architecture of the internet creates risks for democracy
Will democracy survive the internet? Do we need to choose between Facebook’s surveillance capitalism or democracy? Layered lines of evidence can inform questions like these. When considered together, the evidence gives rise to a concerning picture, as summarized in a recent report for the European Commission that I co-led.

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they? One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers. 1/n

I had the pleasure of writing for the BPP Blog, exploring how behavioral science can step up where social media fails to tackle misinformation. Key takeaway: As platforms step back from accountability, a vigilant and resilient public is the strongest shield against misinformation.

As the Trump administration and Elon Musk work to dismantle USAID, the government’s lead agency for delivering humanitarian aid for generations, right-wing influencers have flooded the internet with falsehoods about its work, promoting unfounded claims and conspiratorial thinking. nyti.ms/4htWHN0
A chart shows the increasing views that a viral, false claim about USAID saw on X, as it was amplified by right-wing influencers. A headline reads: Falsehoods Fuel the Right-Wing Crusade Against USAID. A sentence reads: Nearly 15,000 posts on X over two days mentioned USAID and Politico, with many users falsely claiming that the humanitarian organization paid the news website millions of dollars. Note: Data includes posts on X between Feb. 5 at 9 a.m. Eastern Time and Feb. 6 at 10 p.m. that mention both “Politico” and “USAID.” Source: Tweet Binder by Audiense.

How do autocrats stay in power? Our new research dives into the strategies of political control—repression, co-optation, and indoctrination—used across 229 autocracies from 1946 to 2010. What we found will change the way you think about authoritarian resilience. 🧵👇

🌟🧠💪📝 #BOOSTING: Empowering citizens with behavioral science New, freely available paper in Annual Review of Psychology. PDF: tinyurl.com/boosting2025 For more: scienceofboosting.org @arc-mpib.bsky.social @mpib-berlin.bsky.social @annualreviews.bsky.social #policy #behavioralscience 1/ 🧵👇
The image is the cover page of an article from the "Annual Review of Psychology" titled "Boosting: Empowering Citizens with Behavioral Science" by Stefan M. Herzog and Ralph Hertwig. It features a brief abstract, keywords, and publication details. The abstract outlines the concept of "boosting" as a behavioral public policy that emphasizes empowering individuals to make informed decisions, in contrast to "nudging," which subtly steers behavior. The abstract reads:

Behavioral public policy came to the fore with the introduction of nudging, which aims to steer behavior while maintaining freedom of choice. Responding to critiques of nudging (e.g., that it does not promote agency and relies on benevolent choice architects), other behavioral policy approaches focus on empowering citizens. Here we review boosting, a behavioral policy approach that aims to foster people's agency, self-control, and ability to make informed decisions. It is grounded in evidence from behavioral science showing that human decision making is not as notoriously flawed as the nudging approach assumes. We argue that addressing the challenges of our time—such as climate change, pandemics, and the threats to liberal democracies and human autonomy posed by digital technologies and choice architectures—calls for fostering capable and engaged citizens as a first line of response to complement slower, systemic approaches.List with summary points:

1. Behavioral public policy garnered widespread attention with the introduction of nudging, which aims to steer behavior while maintaining freedom of choice.
2. Criticisms of nudging include that it does not promote agency and competences and that it relies—overly optimistically—on the presence of benevolent choice architects.
3. The proliferation of environments threatening people's autonomy, the slow pace of systemic approaches to tackling societal issues, and the intrinsic benefits of empowerment make empowering citizens an indispensable objective of behavioral public policy.
4. Boosting is a behavioral public policy approach to empowerment grounded in evidence from behavioral science that shows that humans’ boundedly rational decision making is not as flawed as the nudging approach assumes.
5. Boosts are interventions that improve people's competencies to make informed choices that conform to their goals, preferences, and desires.
6. In self-nudging boosts, people learn to use architectural changes in their proximate choice environment to regulate their own behavior—that is, they are empowered to adapt their own choice environments.
7. There are boosts to foster core competences in many domains, including finance, online environments, and health, as well as broader, overarching areas, such as motivation, risk, and judgment and decision making. Boosts should be part of a policy mix that also includes system-level approaches.
8. When implementing boosts, policy makers need to avoid the trap of individualizing responsibility and to be mindful that, due to differences in cognition and motivation, inequalities in the desirable effects across boosted individuals may emerge.

On this Jan. 6, it’s a fitting moment to reflect on the threats to democracy posed by norm violations from political elites - and by a public that either supports or turns a blind eye to them. @lewan.bsky.social, @kiiahuttunen.bsky.social, Ralph Hertwig, and I discuss this in a recent publication.
