Crowdsourcing Judgments of News Source Quality

Curated on February 13, 2018August 3, 2018 by Stefaan Verhulst

Paper by Gordon Pennycook and David G. Rand: “The spread of misinformation and disinformation, especially on social media, is a major societal challenge. Here, we assess whether crowdsourced ratings of trust in news sources can effectively differentiate between more and less reliable sources. To do so, we ran a preregistered experiment (N = 1,010 from Amazon Mechanical Turk) in which individuals rated familiarity with, and trust in, 60 news sources from three categories: 1) Mainstream media outlets, 2) Websites that produce hyper-partisan coverage of actual facts, and 3) Websites that produce blatantly false content (“fake news”).

Our results indicate that, despite substantial partisan bias, laypeople across the political spectrum rate mainstream media outlets as far more trustworthy than either hyper-partisan or fake news sources (all but 1 mainstream source, Salon, was rated as more trustworthy than every hyper-partisan or fake news source when equally weighting ratings of Democrats and Republicans).

Critically, however, excluding ratings from participants who are not familiar with a given news source dramatically reduces the difference between mainstream media sources and hyper-partisan or fake news sites. For example, 30% of the mainstream media websites (Salon, the Guardian, Fox News, Politico, Huffington Post, and Newsweek) received lower trust scores than the most trusted fake news site (news4ktla.com) when excluding unfamiliar ratings.

This suggests that rather than being initially agnostic about unfamiliar sources, people are initially skeptical – and thus a lack of familiarity is an important cue for untrustworthiness. Overall, our findings indicate that crowdsourcing media trustworthiness judgments is a promising approach for fighting misinformation and disinformation online, but that trustworthiness ratings from participants who are unfamiliar with a given source should not be ignored….(More)”.

Self-Tracking: Empirical and Philosophical Investigations

Curated on February 12, 2018August 3, 2018 by Stefaan Verhulst

Book edited by Btihaj Ajana: “…provides an empirical and philosophical investigation of self-tracking practices. In recent years, there has been an explosion of apps and devices that enable the data capturing and monitoring of everyday activities, behaviours and habits. Encouraged by movements such as the Quantified Self, a growing number of people are embracing this culture of quantification and tracking in the spirit of improving their health and wellbeing.
The aim of this book is to enhance understanding of this fast-growing trend, bringing together scholars who are working at the forefront of the critical study of self-tracking practices. Each chapter provides a different conceptual lens through which one can examine these practices, while grounding the discussion in relevant empirical examples.
From phenomenology to discourse analysis, from questions of identity, privacy and agency to issues of surveillance and tracking at the workplace, this edited collection takes on a wide, and yet focused, approach to the timely topic of self-tracking. It constitutes a useful companion for scholars, students and everyday users interested in the Quantified Self phenomenon…(More)”.

Feasibility Study of Using Crowdsourcing to Identify Critical Affected Areas for Rapid Damage Assessment: Hurricane Matthew Case Study

Curated on February 12, 2018August 3, 2018 by Stefaan Verhulst

Paper by Faxi Yuan and Rui Liu at the International Journal of Disaster Risk Reduction: “…rapid damage assessment plays a critical role in crisis management. Collection of timely information for rapid damage assessment is particularly challenging during natural disasters. Remote sensing technologies were used for data collection during disasters. However, due to the large areas affected by major disasters such as Hurricane Matthew, specific data cannot be collected in time such as the location information.

Social media can serve as a crowdsourcing platform for citizens’ communication and information sharing during natural disasters and provide the timely data for identifying affected areas to support rapid damage assessment during disasters. Nevertheless, there is very limited existing research on the utility of social media data in damage assessment. Even though some investigation of the relationship between social media activities and damages was conducted, the employment of damage-related social media data in exploring the fore-mentioned relationship remains blank.

This paper for the first time, establishes the index dictionary by semantic analysis for the identification of damage-related tweets posted during Hurricane Matthew in Florida. Meanwhile, the insurance claim data from the publication of Florida Office of Insurance Regulation is used as a representative of real hurricane damage data in Florida. This study performs a correlation analysis and a comparative analysis of the geographic distribution of social media data and damage data at the county level in Florida. We find that employing social media data to identify critical affected areas at the county level during disasters is viable. Damage data has a closer relationship with damage-related tweets than disaster-related tweets….(More)”.

Algorithms of Oppression: How Search Engines Reinforce Racism

Curated on February 11, 2018August 3, 2018 by Stefaan Verhulst

Book by Safiya Umoja Noble: “Run a Google search for “black girls”—what will you find? “Big Booty” and other sexually explicit terms are likely to come up as top search terms. But, if you type in “white girls,” the results are radically different. The suggested porn sites and un-moderated discussions about “why black women are so sassy” or “why black women are so angry” presents a disturbing portrait of black womanhood in modern society.

In Algorithms of Oppression, Safiya Umoja Noble challenges the idea that search engines like Google offer an equal playing field for all forms of ideas, identities, and activities. Data discrimination is a real social problem; Noble argues that the combination of private interests in promoting certain sites, along with the monopoly status of a relatively small number of Internet search engines, leads to a biased set of search algorithms that privilege whiteness and discriminate against people of color, specifically women of color.

Through an analysis of textual and media searches as well as extensive research on paid online advertising, Noble exposes a culture of racism and sexism in the way discoverability is created online. As search engines and their related companies grow in importance—operating as a source for email, a major vehicle for primary and secondary school learning, and beyond—understanding and reversing these disquieting trends and discriminatory practices is of utmost importance.

An original, surprising and, at times, disturbing account of bias on the internet, Algorithms of Oppression contributes to our understanding of how racism is created, maintained, and disseminated in the 21st century….(More)”.

Dawn of the techlash

Curated on February 11, 2018August 3, 2018 by Stefaan Verhulst

Rachel Botsman at the Guardian: “…Once seen as saviours of democracy, those titans are now just as likely to be viewed as threats to truth or, at the very least, impassive billionaires falling down on the job of monitoring their own backyards.

It wasn’t always this way. Remember the early catchy slogans that emerged from those ping-pong-tabled tech temples in Silicon Valley? “A place for friends”, “Don’t be evil” or “You can make money without being evil” (rather poignant, given what was to come). Users were enchanted by the sudden, handheld power of a smartphone to voice anything, access anything; grassroots activist movements revelled in these new tools for spreading their cause. The idealism of social media – democracy, friction-free communication, one-button socialising proved infectious.

So how did that unbridled enthusiasm for all things digital morph into a critical erosion of trust in technology, particularly in politics? Was 2017 the year of reckoning, when technology suddenly crossed to the dark side or had it been heading that way for some time? It might be useful to recall how social media first discovered its political muscle….

Technology is only the means. We also need to ask why our political ideologies have become so polarised, and take a hard look at our own behaviour, as well as that of the politicians themselves and the partisan media outlets who use these platforms, with their vast reach, to sow the seeds of distrust. Why are we so easily duped? Are we unwilling or unable to discern what’s true and what isn’t or to look for the boundaries between opinion, fact and misinformation? But what part are our own prejudices playing?

Luciano Floridi, of the Digital Ethics Lab at Oxford University, points out that technology alone can’t save us from ourselves. “The potential of technology to be a powerful positive force for democracy is huge and is still there. The problems arise when we ignore how technology can accentuate or highlight less attractive sides of human nature,” he says. “Prejudice. Jealousy. Intolerance of different views. Our tendency to play zero sum games. We against them. Saying technology is a threat to democracy is like saying food is bad for you because it causes obesity.”

It’s not enough to blame the messenger. Social media merely amplifies human intent – both good and bad. We need to be honest about our own, age-old appetite for ugly gossip and spreading half-baked information, about our own blindspots.

Is there a solution to it all? Plenty of smart people are working on technical fixes, if for no other reason than the tech companies know it’s in their own best interests to stem the haemorrhaging of trust. Whether they’ll go far enough remains to be seen.

We sometimes forget how uncharted this new digital world remains – it’s a work in progress. We forget that social media, for all its flaws, still brings people together, gives a voice to the voiceless, opens vast wells of information, exposes wrongdoing, sparks activism, allows us to meet up with unexpected strangers. The list goes on. It’s inevitable that there will be falls along the way, deviousness we didn’t foresee. Perhaps the present danger is that in our rush to condemn the corruption of digital technologies, we will unfairly condemn the technologies themselves….(More).

The People’s Right to Know and State Secrecy

Curated on February 10, 2018August 3, 2018 by Stefaan Verhulst

Dorota Mokrosinska at the Canadian Journal of Law and Jurisprudence: “Among the classic arguments which advocates of open government use to fight government secrecy is the appeal to a “people’s right to know.” I argue that the employment of this idea as a conceptual weapon against state secrecy misfires. I consider two prominent arguments commonly invoked to support the people’s right to know government-held information: an appeal to human rights and an appeal to democratic citizenship. While I concede that both arguments ground the people’s right to access government information, I argue that they also limit this right and in limiting it, they establish a domain of state secrecy. The argument developed in the essay provides a novel interpretation of Dennis Thompson’s claim, who in his seminal work on the place of secrecy in democratic governance, has argued that some of the best reasons for secrecy are the same reasons that argue for openness and against secrecy….(More)”.

Managing Democracy in the Digital Age

Curated on February 9, 2018August 3, 2018 by Stefaan Verhulst

Book edited by Julia Schwanholz, Todd Graham and Peter-Tobias Stoll: “In light of the increased utilization of information technologies, such as social media and the ‘Internet of Things,’ this book investigates how this digital transformation process creates new challenges and opportunities for political participation, political election campaigns and political regulation of the Internet. Within the context of Western democracies and China, the contributors analyze these challenges and opportunities from three perspectives: the regulatory state, the political use of social media, and through the lens of the public sphere.

The first part of the book discusses key challenges for Internet regulation, such as data protection and censorship, while the second addresses the use of social media in political communication and political elections. In turn, the third and last part highlights various opportunities offered by digital media for online civic engagement and protest in the public sphere. Drawing on different academic fields, including political science, communication science, and journalism studies, the contributors raise a number of innovative research questions and provide fascinating theoretical and empirical insights into the topic of digital transformation….(More)”.

Landscape of Innovation Approaches

Curated on February 8, 2018October 11, 2018 by Stefaan Verhulst

Bas Leurs at Nesta: “Through our work in the Innovation Skills team, we often find ourselves being asked by governments and civil servants which innovation tools and techniques they should use. So what innovation approaches are there that can be applied in the public sector? And how are they related to each other?

With these questions in mind, over the last couple of years we’ve been mapping out the various innovation methods and approaches we’ve come across from studying innovation practice and our many conversations with different lab practitioners, colleagues and other innovation experts.

Download this diagram as a PDF.

The map we’ve created provides an overview of innovation methods and approaches that help people make sense of reality, and approaches that help develop solutions and interventions to create change.

Understanding and shaping reality

The approaches mapped out in the diagram are structured into four spaces: intelligence, solution, technology and talent. These spaces are built on the premise that in order to create change, you need to make sense and understand reality, as well as develop solutions and interventions to change that reality:

intelligence space – focuses on approaches that help you make sense of and conceptualise reality
solution space – focuses on methods that help you test and develop solutions

In terms of mindsets, you could say that the intelligence space is more academic, whereas the solution space involves more of an entrepreneurial approach. The activities in these are supported by two further spaces:

technology space – includes approaches and technology that enable action and change, such as digital tools and data-related methods
talent space – focuses on how to mobilise talent, develop skills and increase organisational readiness in order to ultimately make change happen…(More)”.

A Really Bad Blockchain Idea: Digital Identity Cards for Rohingya Refugees

Curated on February 8, 2018August 3, 2018 by Stefaan Verhulst

Wayan Vota at ICTworks: “The Rohingya Project claims to be a grassroots initiative that will empower Rohingya refugees with a blockchain-leveraged financial ecosystem tied to digital identity cards….

What Could Possibly Go Wrong?

Concerns about Rohingya data collection are not new, so Linda Raftree‘s Facebook post about blockchain for biometrics started a spirited discussion on this escalation of techno-utopia. Several people put forth great points about the Rohingya Project’s potential failings. For me, there were four key questions originating in the discussion that we should all be debating:

1. Who Determines Ethnicity?

Ethnicity isn’t a scientific way to categorize humans. Ethnic groups are based on human constructs such as common ancestry, language, society, culture, or nationality. Who are the Rohingya Project to be the ones determining who is Rohingya or not? And what is this rigorous assessment they have that will do what science cannot?

Might it be better not to perpetuate the very divisions that cause these issues? Or at the very least, let people self-determine their own ethnicity.

2. Why Digitally Identify Refugees?

Let’s say that we could group a people based on objective metrics. Should we? Especially if that group is persecuted where it currently lives and in many of its surrounding countries? Wouldn’t making a list of who is persecuted be a handy reference for those who seek to persecute more?

Instead, shouldn’t we focus on changing the mindset of the persecutors and stop the persecution?

3. Why Blockchain for Biometrics?

How could linking a highly persecuted people’s biometric information, such as fingerprints, iris scans, and photographs, to a public, universal, and immutable distributed ledger be a good thing?

Might it be highly irresponsible to digitize all that information? Couldn’t that data be used by nefarious actors to perpetuate new and worse exploitation of Rohingya? India has already lost Aadhaar data and the Equafax lost Americans’ data. How will the small, lightly funded Rohingya Project do better?

Could it be possible that old-fashioned paper forms are a better solution than digital identity cards? Maybe laminate them for greater durability, but paper identity cards can be hidden, even destroyed if needed, to conceal information that could be used against the owner.

4. Why Experiment on the Powerless?

Rohingya refugees already suffer from massive power imbalances, and now they’ll be asked to give up their digital privacy, and use experimental technology, as part of an NGO’s experiment, in order to get needed services.

Its not like they’ll have the agency to say no. They are homeless, often penniless refugees, who will probably have no realistic way to opt-out of digital identity cards, even if they don’t want to be experimented on while they flee persecution….(More)”
