The pushback against AI should be contextualized as a strategic boycott opposing Big Tech & Silicon Valley's push to disempower the working class and their complicity in global rise in authoritarianism. If AI is the digital picket line, how do we practice care and empathy in building this movement?

This year, we do not set separate submission tracks for #IR4Good full and short papers. All submissions must be between 6 to 12 pages in length plus additional pages for references. Paper lengths should be commensurate with its contribution.
8/
Submissions of papers must be at least 6 pages (the sixth page should have at least some content but not necessary to fill it) and at most 12 pages in length plus additional pages for references. The "Theory of Change" section and Appendices count toward the page limit. Please put appendices before the references for paper submission. While this year we do not set separate submission tracks for full and short papers in the IR-for-Good track, the assessment of each submission will be based on whether the paper length is commensurate with its contribution. For example, a 6-page paper would be accepted if its scientific contribution is worth 6 pages. However, a 12-page paper would be considered weak if it only contains the substance of a 6-page paper.

The CFP includes several example cases to illustrate the kind of critical reflections we want to encourage authors and reviewers to engage in when claiming societal impact.
7/
Claim: Our work that proposes a method for making expensive machine learning models for IR more efficient contributes towards sustainability and reducing impact on the environment. Considerations for this claim: What preconditions are necessary for the efficiency improvements to translate to reduced impact on the environment? E.g., according to the Jevons paradox in economics, when technological advancements make a resource more efficient to use (thereby reducing the amount needed for a single application) it often results in overall increase in demand, causing total resource consumption to rise instead of falling. Is it more likely then that more efficient models may in fact lead to a false sense of mitigation and result in much wider adoption contributing to increased harm to the environment? Claim: Our work that improves alignment of LLMs towards specific social values contributes towards user safety by preventing exposure to harmful content. Considerations for this claim: Who gets to decide what is harmful or select the values the system should be aligned with? Could these approaches in fact further centralize power and control over what is deemed "acceptable" vs. "harmful" speech? Could this stifle the voices of marginalized people and social activists? Could this incentivize authoritarian capture of information access platforms to manipulate public opinion? Does the proposed approach consider both the social and technical aspects of this problem to ensure democratic oversight and emancipatory outcomes? Claim: Our work that proposes new methods for generating explanations for model outputs contributes towards increasing user trust in the system. Considerations for this claim: Is that trust beneficial or harmful for the user? Is that trust warranted or could it in fact draw users into a false sense of safety and distract them from noticing how the system surveils them and subtly manipulates their behavior? How can this explainability intervention actually help reveal and challenge existing power structures? Claim: Our work that proposes a new ranking approach for gender fairness contributes towards gender justice. Considerations for this claim: How does the adopted definition of "gender fairness" in this work translate to mitigating real-world "gender discrimination"? Does this work assume that gender is binary, erasing other identities? Does this work assume that gender is known for all users / subjects and incentivize further intensification of surveillance and collection of private demographic data from members of historically marginalized communities? How can this work be operationalized in practice towards gender and sexuality justice? Are there example use-cases where this can be reliably demonstrated (e.g., ranking in hiring or job recommendation applications)?

Authors should critically engage with these questions, not just as an afterthought. Do not inflate your claims of societal impact, instead rigorously deliberate on your sociotechnical assumptions and potential negative externalities.
6/
We encourage authors and reviewers to critically engage with this section while acknowledging the real uncertainty of how any well-intentioned research may impact society in practice. Our goal is not to encourage authors to inflate their claims of social impact but to rigorously deliberate on their sociotechnical assumptions and enumerate the necessary preconditions for the work to have its desired impact and also potential negative externalities. We recommend that the "Theory of Change" section should explicitly state: 1. What is the identified societal need / problem, and how are the core contributions from this current work expected to address them? 2. What preconditions are necessary or what assumptions need to hold for this work to have its desired effect, and how likely are they to hold true in practice? 3. What are possible negative externalities of this approach and is it plausible that this may lead to new or different harms? Authors are encouraged to include any additional discussions that they may deem relevant in this section.

To ensure desired societal impact, this year we require all submissions that propose new tools, methods, datasets, and interventions to explicitly and rigorously argue how the work contributes towards positive social outcomes. Position papers and critiques are exempted.
5/
**Theories of Change** IR research that tries to affect positive social change needs to be grounded in rigorous understanding of the sociotechnical challenges and the complex socio-political context in which they exist. We require every submission that proposes new IR tools, methods, datasets, and interventions to explicitly include a separate section elaborating how the work contributes towards desired social outcomes, i.e., their theory of change. This section should not be an afterthought, instead it should be a critical part of the core motivation of the work. It is not mandatory to name the section "Theory of change" and position papers and critiques are exempted from this requirement.

💯 The goal of AI hype *is* to provide political cover for further defunding of our healthcare and education systems while diverting capital to big tech. #LetThemEatChatbots

This work is difficult. It requires reconciling collective risks with individual circumstances. We must resist Big Tech's attempts at prying open the cracks in our solidarity to claim AI-shaming is ableist or classist.
/14
Screenshot that reads: "Workers of the world, unite! This is the moment for movement building. It is incredibly difficult work, as it always has been throughout history. It requires us to reconcile collective risks and systemic harms with individual circumstances. I am empathetic towards those who may genuinely find these tools useful. I am aware of some of the ongoing debates around AI art and accessibility, and again I empathize with those arguments. I don’t believe these positions are irreconcilable, but it does require bringing a multitude of people to the table to build solidarity, find workable solutions, collectively strategize, and build a movement. Because we cannot let Big Tech co-opt our differences to divide and defeat us. We should resist when Big Tech tries to pry open those cracks and claim that AI shaming is “ableist” or that it arises from “class anxiety induced in middle class knowledge workers” and intended to protect “privileged class of knowledge work”. Nuh uh! Our liberation is bound together and capitulating to the politics of AI hype will be catastrophic for the entirety of the working class. And we must also outright oppose when Big Tech claims that the path forward is to “upskill artists and knowledge workers to leverage AI” because training artists and knowledge workers to prompt an AI model is not teaching them a meaningful new skill but luring them to abdicate their craft, creativity, and critical thinking. So, workers of the world, unite! We have nothing to lose but our cha… chatbots."

This work must be grounded in movement building and our emancipatory praxis.
13/
Screenshot that reads: "But this is not a call for idle speculation, this must be an integral part of our day-to-day emancipatory praxis. For example, if you work on developing AI tools and systems for knowledge work, ask yourself who you are building it for, the workers or the bosses? How would your approach and design fundamentally change if your goal was explicitly to shift power from bosses to workers? What mechanisms of collective action and resistance would you build in into the system design? What technologies would you develop to empower artists and knowledge workers to safeguard the artefacts they produce from being commodified and appropriated (example)? What direct actions can you take today to challenge the AI hype and its uncritical adoption within the tech community? What spaces can you create for collective learning about the history of labor movements, for collective sensemaking of our current challenges and risks, and for collective organizing (unions and otherwise)? We must remember that it is not just our desired futures that should inform our actions in this present moment, but also our past. Learn about the true history of the Luddite uprising, and ask yourself what would be the equivalent of “machine breaking” for our generation?" followed by an image of the cover of Brian Merchant's book "Blood in the machine".

To resist, we must both radically reimagine our possible futures and learn from movements from our past.
12/
Screenshot that reads: "Imagining new futures, learning from our past It doesn’t have to be this way. Technology is not inherently repressive. But it does have its politics. Technology is shaped by our visions of desired futures, and in turn actualizes social transformations towards envisioned futures. And that is why the AI hype is dangerous because it manufactures a crisis of imagination, trying to convince everyone that the path we are on is the only possible future, and aggressively rebukes anyone for questioning or resisting their desired future being forced on all of us." with the Ursula K. Le Guin quote "The exercise of imagination is dangerous to those who profit from the way things are because it has the power to show that the way things are is not permanent, not universal, not necessary."

And, the environmental impacts of global data center expansion for AI are also being felt disproportionately by already marginalized and vulnerable working class communities.
11/
Screenshot that reads: "The environmental costs of AI The environmental impacts of global data center expansion for AI are also being felt disproportionately by already marginalized and vulnerable communities. Climate change is a racial justice issue. Climate change is a social justice issue. Instead of investing in our social infrastructure, protecting the already vulnerable communities, and taking drastic steps to reduce our fossil fuel emissions, Big Tech wants you to believe that AI will solve climate change. Of course, it won’t. And coincidentally all of Big Tech’s climate pledges are also a hot mess (pun intended). It is remarkable to me that of all things it is chatbots that the ruling class has decided is worth burning the whole planet down for. This is naked necropolitics." followed by the New Yorker cartoon: https://www.newyorker.com/cartoon/a16995.

Beyond the commodification and appropriation of labor, AI is also providing political cover for ongoing dismantling of social services globally.
10/
Screenshot that reads: "Let them eat chatbots The adverse effects of AI on the working class are not restricted to the commodification and appropriation of labor. AI technologies are also being positioned to provide cover for depriving the working class from basic services such as healthcare and education. Most of us I imagine have heard at least one AI-bro predict that the solution to the scarcity of doctors, teachers, and therapists in under-funded communities is to give them access to AI chatbots designed to serve in those functions. This idea is not just particularly ill-premised, it is maliciously ableist, classist, and racist, and mirrors the already ongoing dismantling of social services globally. Our communities globally are suffering from lack of investments in those communities because of generations of class, colonial, and racial oppression. A capitalist society only invests in communities to the extent that it in return supports more capital accumulation for them. It wants us to forget that healthcare and wellbeing are universal rights, not privileges. It wants to forget that education is supposed to liberate us and teach us to find community in each other, not to be perfectly shaped into cogs for the capitalist machine. So, of course instead of meaningful investments in our communities to affect social change it wants us to further divert investments towards Big Tech. Chatbots in this context aren’t meant to be real solutions, just a placebo for the masses, and a cover for further dismantling of our social infrastructure. Put Big Tech in charge of education and it almost surely also guarantees further dismantling of Humanities and every other critical pedagogy that is supposed to teach us to resist capitalism, colonization, and oppression."

AI models do not just appropriate our labor, but also our identities.
9/
Screenshot that reads: "The ghost in the machine is us When AI models are trained on writings and other works of people, it is not merely appropriating their labor but also their identities. Imagine a film, a video game, or a video ad that includes an AI-generated character who is Black. The character was created based on limited instructions in the prompt with the AI model filling in all the remaining details. No Black person was hired to play that character nor to write it. The AI model is simply drawing from the ghostly echoes of all the stories and lived experiences of real Black people in its training data. The model nor the person using it to create the character could ever experience the joys or the struggles of being Black, nor can they truly appreciate the history and culture of its peoples. The character wears that identity as a hollow shell, reconstructed from an amalgamation of the entirety of human experience as it is shallowly reflected on the web, and has its strings pulled to say or act in ways that a real Black person might strongly oppose to. This is the new “Digital Blackface”. This is the great displacement of art that tells the stories of its peoples by synthetic content."

Who gets to benefit from “AI”? And who is delegated to the role of providing data labor? The answers mirror racial capitalism and coloniality, and reinforce the global north and south divide.
8/
Screenshot that reads: "AI for me, data labor for thee Another pernicious aspect of AI data labor dynamics is how they mirror and reify racial capitalism and coloniality, employ global labor exploitation and extractive practices, and reinforce the global north and south divide. While worldwide jobs might be created in certain cases, the workers are typically low paid and deprived of any share of the profit made from technologies built with their labor. These dynamics encompass accruing the benefits of generative AI to privileged populations in western and other rich countries, while data labor is relegated to already marginalized populations, for example, in the global south. Communities that significantly contribute to AI data labor may even find their own linguistic styles being labeled AI-ese and being forced to repeatedly prove their own humanity."

It is particularly harmful that these AI tech that displaces workers/artists and commodifies their labor are built on theft and appropriation of data labor from the same workers and artists.
7/
Screenshot that reads: "Grand theft data labor Data labor is defined as “activities that produce digital records useful for capital generation”. Appropriation of data labor includes underpaid crowd work for data labeling and content moderation that are critical for training and operationalizing AI models. It also includes the uncompensated appropriation of works by writer, artists, and programmers created outside of the AI development process that are nonetheless extracted from the Web and fed in as training data to generative AI models. It furthermore includes the user behavior data and other data generated when users interact with and participate on the platforms, i.e., simply by using these systems, they generate more data for the AI model to train on to further automate exactly the type of tasks they are currently performing. It is particularly harmful that these AI technologies developed on appropriated labor is then employed to displace and automate the jobs of those whose labor was appropriated, e.g., artists, coders, and other knowledge workers. This may result in vicious cycles of skill transfer from people to AI models whereby proprietary AI model capabilities continue to improve—by learning from both what the workers produce and from the traces of their personal workflows captured by the AI platforms when workers interact with them—while workers progressively lose their economic value and power."
