Is bigger better? A study of the effect of group size on collective intelligence in online groups


Paper by Nada Hashmi, G. Shankaranarayanan and Thomas W. Malone: “What is the optimal size for online groups that use electronic communication and collaboration tools? Previous research typically suggested optimal group sizes of about 5 to 7 members, but this research predominantly examined in-person groups. Here we investigate online groups whose members communicate with each other using two electronic collaboration tools: text chat and shared editing. Unlike previous research that studied groups performing a single task, here we measure group performance using a test of collective intelligence (CI) that includes a combination of tasks specifically chosen to predict performance...

All Eyes on Them: A Field Experiment on Citizen Oversight and Electoral Integrity


Paper by Natalia Garbiras-Díaz and Mateo Montenegro: “Can information and communication technologies help citizens monitor their elections? We analyze a large-scale field experiment designed to answer this question in Colombia. We leveraged Facebook advertisements sent to over 4 million potential voters to encourage citizen reporting of electoral irregularities. We also cross-randomized whether candidates were informed about the campaign in a subset of municipalities. Total reports, and evidence-backed ones, experienced a large increase. Across a wide array of measures, electoral irregularities decreased. Finally, the reporting campaign reduced the vote share of candidates dependent on irregularities. This light-touch intervention is more... (More >)

Virtual Public Involvement: Lessons from the COVID-19 Pandemic


Report by the National Academies: “During the COVID-19 pandemic, transportation agencies’ most used public-engagement tools were virtual public meetings, social media, dedicated project websites or webpages, email blasts, and electronic surveys. As the pandemic subsides, virtual and hybrid models continue to provide opportunities and challenges. The TRB National Cooperative Highway Research Program’s NCHRP Web-Only Document 349: Virtual Public Involvement: Lessons from the COVID-19 Pandemic discusses gaps that need to be addressed so that transportation agencies can better use virtual tools and techniques to facilitate two-way communication with the public...

The Risks of Empowering “Citizen Data Scientists”


Article by Reid Blackman and Tamara Sipes: “New tools are enabling organizations to invite and leverage non-data scientists — say, domain data experts, team members very familiar with the business processes, or heads of various business units — to propel their AI efforts. There are advantages to empowering these internal “citizen data scientists,” but also risks. Organizations considering implementing these tools should take five steps: 1) provide ongoing education, 2) provide visibility into similar use cases throughout the organization, 3) create an expert mentor program, 4) have all projects verified by AI experts, and 5) provide resources for inspiration...

The Power of Partnership in Open Government


Book by by Suzanne J. Piotrowski, Daniel Berliner and Alex Ingrams: “At the 2011 meeting of the UN General Assembly, the governments of eight nations—Brazil, Indonesia, Mexico, Norway, Philippines, South Africa, the United Kingdom, and the United States—launched the Open Government Partnership, a multilateral initiative aimed at promoting transparency, empowering citizens, fighting corruption, and harnessing new technologies to strengthen governance. At the time, many were concerned that the Open Government Partnership would end up toothless, offering only lip service to vague ideals and misguided cyber-optimism. The Power of Partnership in Open Government offers a close look, and a surprising... (More >)

The rise and fall of peer review


Blog by Adam Mastroianni: “For the last 60 years or so, science has been running an experiment on itself. The experimental design wasn’t great; there was no randomization and no control group. Nobody was in charge, exactly, and nobody was really taking consistent measurements. And yet it was the most massive experiment ever run, and it included every scientist on Earth. Most of those folks didn’t even realize they were in an experiment. Many of them, including me, weren’t born when the experiment started. If we had noticed what was going on, maybe we would have demanded a basic... (More >)

A catalyst for community-wide action on sustainable development


Article by Communities around the world are increasingly recognizing that breaking down silos and leveraging shared resources and interdependencies across economic, social, and environmental issues can help accelerate progress on multiple issues simultaneously. As a framework for organizing local development priorities, the world’s 17 Sustainable Development Goals (SDGs) uniquely combine a need for broad technical expertise with an opportunity to synergize across domains—all while adhering to the principle of leaving no one behind. For local leaders attempting to tackle intersecting issues using the SDGs, one underpinning question is how to support new forms of collaboration to maximize impact and... (More >)

Which Connections Really Help You Find a Job?


Article by Iavor Bojinov, Karthik Rajkumar, Guillaume Saint-Jacques, Erik Brynjolfsson, and Sinan Aral: “Whom should you connect with the next time you’re looking for a job? To answer this question, we analyzed data from multiple large-scale randomized experiments involving 20 million people to measure how different types of connections impact job mobility. Our results, published recently in Science Magazine, show that your strongest ties — namely your connections to immediate coworkers, close friends, and family — were actually the least helpful for finding new opportunities and securing a job. You’ll have better luck with your weak ties: the more... (More >)

Research Methods in Deliberative Democracy


Book edited by Selen A. Ercan et al: “… brings together a wide range of methods used in the study of deliberative democracy. It offers thirty-one different methods that scholars use for theorizing, measuring, exploring, or applying deliberative democracy. Each chapter presents one method by explaining its utility in deliberative democracy research and providing guidance on its application by drawing on examples from previous studies. The book hopes to inspire scholars to undertake methodologically robust, intellectually creative, and politically relevant research. It fills a significant gap in a rapidly growing field of research by assembling diverse methods and thereby... (More >)

Learnings on the Importance of Youth Engagement


Blog by Anna Ibru and Dane Gambrell at The GovLab: “…In recent years, public institutions around the world are piloting new youth engagement initiatives like Creamos that tap the expertise and experiences of young people to develop projects, programs, and policies and address complex social challenges within communities. To learn from and scale best practices from international models of youth engagement, The GovLab has develop case studies about three path breaking initiatives: Nuortenbudjetti, Helsinki’s participatory budgeting initiative for youth; Forum Jove BCN, Barcelona’s youth led citizens’ assembly; and Creamos, an open innovation and coaching program for young social innovators...
