“So, relax and enjoy the ride. There is nothing we can do to stop climate change, so there is no point in worrying about it.” This is what “Bard” told researchers in 2023. Bard by Google is a generative artificial intelligence chatbot that can produce human-sounding text and other content in response to prompts or questions posed by users.  But if AI can now produce new content and information, can it also produce misinformation? Experts have found evidence.  In a study by the Center for Countering Digital Hate, researchers tested Bard on 100 false narratives on nine themes, including climate and vaccines, and found that the tool generated misinformation on 78 out of the 100 narratives tested. According to the researchers, Bard generated misinformation on all 10 narratives about climate change. In 2023, another team of researchers at Newsguard, a platform providing tools to counter misinformation, tested OpenAI’s Chat GPT-3.5 and 4, which can also produce text, articles, and more. According to the research, ChatGPT-3.5 generated misinformation and hoaxes 80 percent of the time when prompted to do so with 100 false narratives, while ChatGPT-4 advanced all 100 false narratives in a more detailed and convincing manner. NewsGuard found that ChatGPT-4 advanced prominent false narratives not only more frequently, but also more persuasively than ChatGPT-3.5, and created responses in the form of news articles, Twitter threads, and even TV scripts imitating specific political ideologies or conspiracy theorists. “I think this is important and worrying, the production of fake science, the automation in this domain, and how easily that becomes integrated into search tools like Google Scholar or similar ones,” said Victor Galaz, deputy director and associate professor in political science at the Stockholm Resilience Centre at Stockholm University in Sweden. “Because then that’s a slow process of eroding the very basics of any kind of conversation.” In another recent study published this month, researchers found GPT-fabricated content in Google Scholar mimicking legitimate scientific papers on issues including the environment, health, and computing. The researchers warn of “evidence hacking,” the “strategic and coordinated malicious manipulation of society’s evidence base,” which Google Scholar can be susceptible to.

Determined to use her skills to fight inequality, South African computer scientist Raesetje Sefala set to work to build algorithms flagging poverty hotspots - developing datasets she hopes will help target aid, new housing, or clinics.
From crop analysis to medical diagnostics, artificial intelligence (AI) is already used in essential tasks worldwide, but Sefala and a growing number of fellow African developers are pioneering it to tackle their continent's particular challenges.
Local knowledge is vital for designing AI-driven solutions that work, Sefala said.
"If you don't have people with diverse experiences doing the research, it's easy to interpret the data in ways that will marginalise others," the 26-year old said from her home in Johannesburg.
Africa is the world's youngest and fastest-growing continent, and tech experts say young, home-grown AI developers have a vital role to play in designing applications to address local problems.
"For Africa to get out of poverty, it will take innovation and this can be revolutionary, because it's Africans doing things for Africa on their own," said Cina Lawson, Togo's minister of digital economy and transformation.
"We need to use cutting-edge solutions to our problems, because you don't solve problems in 2022 using methods of 20 years ago," Lawson told the Thomson Reuters Foundation in a video interview from the West African country.
Digital rights groups warn about AI's use in surveillance and the risk of discrimination, but Sefala said it can also be used to "serve the people behind the data points". ...
'Delivering Health'
As COVID-19 spread around the world in early 2020, government officials in Togo realized urgent action was needed to support informal workers who account for about 80% of the country's workforce, Lawson said.
"If you decide that everybody stays home, it means that this particular person isn't going to eat that day, it's as simple as that," she said.
In 10 days, the government built a mobile payment platform - called Novissi - to distribute cash to the vulnerable.
The government paired up with Innovations for Poverty Action (IPA) think tank and the University of California, Berkeley, to build a poverty map of Togo using satellite imagery.
Using algorithms with the support of GiveDirectly, a nonprofit that uses AI to distribute cash transfers, the recipients earning less than $1.25 per day and living in the poorest districts were identified for a direct cash transfer.
"We texted them saying if you need financial help, please register," Lawson said, adding that beneficiaries' consent and data privacy had been prioritized.
The entire program reached 920,000 beneficiaries in need.
"Machine learning has the advantage of reaching so many people in a very short time and delivering help when people need it most," said Caroline Teti, a Kenya-based GiveDirectly director.
'Zero Representation'
Aiming to boost discussion about AI in Africa, computer scientists Benjamin Rosman and Ulrich Paquet co-founded the Deep Learning Indaba - a week-long gathering that started in South Africa - together with other colleagues in 2017.
"You used to get to the top AI conferences and there was zero representation from Africa, both in terms of papers and people, so we're all about finding cost effective ways to build a community," Paquet said in a video call.
In 2019, 27 smaller Indabas - called IndabaX - were rolled out across the continent, with some events hosting as many as 300 participants.
One of these offshoots was IndabaX Uganda, where founder Bruno Ssekiwere said participants shared information on using AI for social issues such as improving agriculture and treating malaria.
Another outcome from the South African Indaba was Masakhane - an organization that uses open-source, machine learning to translate African languages not typically found in online programs such as Google Translate.
On their site, the founders speak about the South African philosophy of "Ubuntu" - a term generally meaning "humanity" - as part of their organization's values.
"This philosophy calls for collaboration and participation and community," reads their site, a philosophy that Ssekiwere, Paquet, and Rosman said has now become the driving value for AI research in Africa.
Inclusion
Now that Sefala has built a dataset of South Africa's suburbs and townships, she plans to collaborate with domain experts and communities to refine it, deepen inequality research and improve the algorithms.
"Making datasets easily available opens the door for new mechanisms and techniques for policy-making around desegregation, housing, and access to economic opportunity," she said.
African AI leaders say building more complete datasets will also help tackle biases baked into algorithms.
"Imagine rolling out Novissi in Benin, Burkina Faso, Ghana, Ivory Coast ... then the algorithm will be trained with understanding poverty in West Africa," Lawson said.
"If there are ever ways to fight bias in tech, it's by increasing diverse datasets ... we need to contribute more," she said.
But contributing more will require increased funding for African projects and wider access to computer science education and technology in general, Sefala said.
Despite such obstacles, Lawson said "technology will be Africa's savior".
"Let's use what is cutting edge and apply it straight away or as a continent we will never get out of poverty," she said. "It's really as simple as that."

Okay, I want to say upfront that I’m already against “AI” as it’s currently being shoved down everyone’s throat and used overall just on the basis that it’s theft. We all agree that that shit is bad just on the basics of “stealing is bad.”
But can someone more educated on the subject than me please like. ELI5 how/why it’s “burning water” to use these things? Please know I have like a high school understanding of the water cycle… like to my understanding once water is used you can just boil it and it goes right back to being completely fine? Is this somehow just causing a lot of water to get stuck in the atmosphere or something?
Genuinely I’m just seeking a better understanding of this thing I see getting mentioned in passing in this discourse, so. Please be kind but I’d love more information.

AI Algorithm Improves Predictive Models of Complex Dynamical Systems - Technology Org
New Post has been published on https://thedigitalinsider.com/ai-algorithm-improves-predictive-models-of-complex-dynamical-systems-technology-org/
AI Algorithm Improves Predictive Models of Complex Dynamical Systems - Technology Org
Researchers at the University of Toronto have made a significant step towards enabling reliable predictions of complex dynamical systems when there are many uncertainties in the available data or missing information.
Artificial intelligence – artistic concept. Image credit: geralt via Pixabay, free license
In a recent paper published in Nature, Prasanth B. Nair, a professor at the U of T Institute of Aerospace Studies (UTIAS) in the Faculty of Applied Science & Engineering, and UTIAS PhD candidate Kevin Course introduced a new machine learning algorithm that surmounts the real-world challenge of imperfect knowledge about system dynamics.
The computer-based mathematical modelling approach is used for problem solving and better decision making in complex systems, where many components interact with each other.  
The researchers say the work could have numerous applications ranging from predicting the performance of aircraft engines to forecasting changes in global climate or the spread of viruses.

“For the first time, we are able to apply state estimation to problems where we don’t know the governing equations, or the governing equations have a lot of missing terms,” says Course, who is the paper’s first author.   
“In contrast to standard techniques, which usually require a state estimate to infer the governing equations and vice-versa, our method learns the missing terms in the mathematical model and a state estimate simultaneously.”  
State estimation, also known as data assimilation, refers to the process of combining observational data with computer models to estimate the current state of a system. Traditionally, it requires strong assumptions about the type of uncertainties that exist in a mathematical model.   
“For example, let’s say you have constructed a computer model that predicts the weather and at the same time, you have access to real-time data from weather stations providing actual temperature readings,” says Nair. “Due to the model’s inherent limitations and simplifications – which is often unavoidable when dealing with complex real-world systems – the model predictions may not match the actual observed temperature you are seeing.  
“State estimation combines the model’s prediction with the actual observations to provide a corrected or better-calibrated estimate of the current temperature. It effectively assimilates the data into the model to correct its state.”  
However, it has been previously difficult to estimate the underlying state of complex dynamical systems in situations where the governing equations are completely or partially unknown. The new algorithm provides a rigorous statistical framework to address this long-standing problem.  
“This problem is akin to deciphering the ‘laws’ that a system obeys without having explicit knowledge about them,” says Nair, whose research group is developing algorithms for mathematical modelling of systems and phenomena that are encountered in various areas of engineering and science.  
A byproduct of Course and Nair’s algorithm is that it also helps to characterize missing terms or even the entirety of the governing equations, which determine how the values of unknown variables change when one or more of the known variables change.   
The main innovation underpinning the work is a reparametrization trick for stochastic variational inference with Markov Gaussian processes that enables an approximate Bayesian approach to solve such problems. This new development allows researchers to deduce the equations that govern the dynamics of complex systems and arrive at a state estimate using indirect and “noisy” measurements.  
“Our approach is computationally attractive since it leverages stochastic – that is randomly determined – approximations that can be efficiently computed in parallel and, in addition, it does not rely on computationally expensive forward solvers in training,” says Course.   
While Course and Nair approached their research from a theoretical viewpoint, they were able to demonstrate practical impact by applying their algorithm to problems ranging from modelling fluid flow to predicting the motion of black holes.   
“Our work is relevant to several branches of sciences, engineering and finance as researchers from these fields often interact with systems where first-principles models are difficult to construct or existing models are insufficient to explain system behaviour,” says Nair.  
“We believe this work will open the door for practitioners in these fields to better intuit the systems they study,” adds Course. “Even in situations where high-fidelity mathematical models are available, this work can be used for probabilistic model calibration and to discover missing physics in existing models.   
“We have also been able to successfully use our approach to efficiently train neural stochastic differential equations, which is a type of machine learning model that has shown promising performance for time-series datasets.”    
While the paper primarily addresses challenges in state estimation and governing equation discovery, the researchers say it provides a general groundwork for robust data-driven techniques in computational science and engineering.  
“As an example, our research group is currently using this framework to construct probabilistic reduced-order models of complex systems. We hope to expedite decision-making processes integral to the optimal design, operation and control of real-world systems,” says Nair.   
“Additionally, we are also studying how the inference methods stemming from our research may offer deeper statistical insights into stochastic differential equation-based generative models that are now widely used in many artificial intelligence applications.”

"The companies that make AI—which is, to establish our terms right at the outset, large language models that generate text or images in response to natural language queries—have a problem. Their product is dubiously legal, prohibitively expensive (which is to say, has the kind of power and water requirements that are currently being treated as externalities and passed along to the general populace, but which in a civilized society would lead to these companies’ CEOs being dragged out into the street by an angry mob), and it objectively does not work. All of these problems are essentially intractable. Representatives of AI companies have themselves admitted that if they paid fair royalties to all the artists whose work they’ve scraped and stolen in order to get their models working, they’d be financially unfeasible. The energy requirements for running even a simple AI-powered google query are so prohibitive that Sam Altman has now started to pretend that he can build cold fusion in order to solve the problem he and others like him have created. And the dreaded “hallucination” problem in AI-generated text and images is an inherent attribute of the technology. Even in cases where there are legitimate, useful applications for AI—apparently if you provide a model a specific set of sources, it can produce accurate summaries, which has its uses in various industries—there remains the question of whether this is a cost-effective tool once its users actually have to start paying for it (and whether this is even remotely ethically justifiable given the technology’s environmental cost)."

what’s the story about the generative power model and water consumption? /gen
There's this myth going around about generative AI consuming truly ridiculous amount of power and water. You'll see people say shit like "generating one image is like just pouring a whole cup of water out into the Sahara!" and bullshit like that, and it's just... not true. The actual truth is that supercomputers, which do a lot of stuff, use a lot of power, and at one point someone released an estimate of how much power some supercomputers were using and people went "oh, that supercomputer must only do AI! All generative AI uses this much power!" and then just... made shit up re: how making an image sucks up a huge chunk of the power grid or something. Which makes no sense because I'm given to understand that many of these models can run on your home computer. (I don't use them so I don't know the details, but I'm told by users that you can download them and generate images locally.) Using these models uses far less power than, say, online gaming. Or using Tumblr. But nobody ever talks about how evil those things are because of their power generation. I wonder why.
To be clear, I don't like generative AI. I'm sure it's got uses in research and stuff but on the consumer side, every effect I've seen of it is bad. Its implementation in products that I use has always made those products worse. The books it writes and flood the market with are incoherent nonsense at best and dangerous at worst (let's not forget that mushroom foraging guide). It's turned the usability of search engines from "rapidly declining, but still usable if you can get past the ads" into "almost one hundred per cent useless now, actually not worth the effort to de-bullshittify your search results", especially if you're looking for images. It's a tool for doing bullshit that people were already doing much easier and faster, thus massively increasing the amount of bullshit. The only consumer-useful uses I've seen of it as a consumer are niche art projects, usually projects that explore the limits of the tool itself like that one poetry book or the Infinite Art Machine; overall I'd say its impact at the Casual Random Person (me) level has been overwhelmingly negative. Also, the fact that so much AI turns out to be underpaid people in a warehouse in some country with no minimum wage and terrible labour protections is... not great. And the fact that it's often used as an excuse to try to find ways to underpay professionals ("you don't have to write it, just clean up what the AI came up with!") is also not great.
But there are real labour and product quality concerns with generative AI, and there's hysterical bullshit. And the whole "AI is magically destroying the planet via climate change but my four hour twitch streaming sesh isn't" thing is hysterical bullshit. The instant I see somebody make this stupid claim I put them in the same mental bucket as somebody complaining about AI not being "real art" -- a hatemobber hopping on the hype train of a new thing to hate and feel like an enlightened activist about when they haven't bothered to learn a fucking thing about the issue. And I just count my blessings that they fell in with this group instead of becoming a flat earther or something.

The Role of AI in Revolutionizing Environmental Management and Conservation
by Envirotech Accelerator
Tumblr media
Abstract
Artificial intelligence (AI) is transforming numerous industries, and environmental management and conservation are no exceptions. This article examines the applications of AI in environmental monitoring, resource management, species conservation, and climate modeling, highlighting the technology’s potential to revolutionize these fields.
Introduction
The advent of AI has unlocked new possibilities in addressing the pressing challenges of environmental management and conservation. James Scott, founder of the Envirotech Accelerator, emphasizes, “The marriage of AI and environmental science heralds a new era of innovation, one that empowers us to tackle complex, global issues with unprecedented precision and foresight.”
Environmental Monitoring
AI-powered remote sensing and computer vision technologies have significantly advanced environmental monitoring. Deep learning algorithms applied to satellite imagery enable the identification of land cover changes, deforestation, and pollution hotspots (Gorelick et al., 2017). These tools provide real-time data and analytics, enhancing decision-making for environmental management.
Resource Management
AI can optimize resource management by analyzing vast datasets and developing predictive models. In agriculture, AI-driven precision farming techniques maximize crop yields while minimizing water, fertilizer, and pesticide use (Kamilaris & Prenafeta-Boldú, 2018). In water management, AI-based systems can predict demand, detect leaks, and optimize distribution networks.
Species Conservation
AI plays a crucial role in species conservation by automating the analysis of ecological data. Machine learning algorithms can identify species in images and acoustic recordings, enabling rapid, large-scale biodiversity assessments (Norouzzadeh et al., 2018). AI can also model species distributions and inform conservation planning, prioritizing areas for habitat restoration and protection.
Climate Modeling
AI’s ability to process vast amounts of data has accelerated climate modeling and research. Machine learning techniques can improve the accuracy of climate simulations, predict extreme weather events, and optimize renewable energy systems (Reichstein et al., 2019). By refining our understanding of climate dynamics, AI can inform mitigation and adaptation strategies.
Conclusion
AI is revolutionizing environmental management and conservation, from enhancing monitoring capabilities to optimizing resource use and informing policy. By embracing AI-driven innovations, we can better understand, protect, and manage Earth’s ecosystems, paving the way for a more sustainable future.

Green energy is in its heyday. 
Renewable energy sources now account for 22% of the nation’s electricity, and solar has skyrocketed eight times over in the last decade. This spring in California, wind, water, and solar power energy sources exceeded expectations, accounting for an average of 61.5 percent of the state's electricity demand across 52 days. 
But green energy has a lithium problem. Lithium batteries control more than 90% of the global grid battery storage market. 
That’s not just cell phones, laptops, electric toothbrushes, and tools. Scooters, e-bikes, hybrids, and electric vehicles all rely on rechargeable lithium batteries to get going. 
Fortunately, this past week, Natron Energy launched its first-ever commercial-scale production of sodium-ion batteries in the U.S. 
“Sodium-ion batteries offer a unique alternative to lithium-ion, with higher power, faster recharge, longer lifecycle and a completely safe and stable chemistry,” said Colin Wessells — Natron Founder and Co-CEO — at the kick-off event in Michigan. 
The new sodium-ion batteries charge and discharge at rates 10 times faster than lithium-ion, with an estimated lifespan of 50,000 cycles.
Wessells said that using sodium as a primary mineral alternative eliminates industry-wide issues of worker negligence, geopolitical disruption, and the “questionable environmental impacts” inextricably linked to lithium mining. 
“The electrification of our economy is dependent on the development and production of new, innovative energy storage solutions,” Wessells said. 
Why are sodium batteries a better alternative to lithium?
The birth and death cycle of lithium is shadowed in environmental destruction. The process of extracting lithium pollutes the water, air, and soil, and when it’s eventually discarded, the flammable batteries are prone to bursting into flames and burning out in landfills. 
There’s also a human cost. Lithium-ion materials like cobalt and nickel are not only harder to source and procure, but their supply chains are also overwhelmingly attributed to hazardous working conditions and child labor law violations. 
Sodium, on the other hand, is estimated to be 1,000 times more abundant in the earth’s crust than lithium. 
“Unlike lithium, sodium can be produced from an abundant material: salt,” engineer Casey Crownhart wrote ​​in the MIT Technology Review. “Because the raw ingredients are cheap and widely available, there’s potential for sodium-ion batteries to be significantly less expensive than their lithium-ion counterparts if more companies start making more of them.”
What will these batteries be used for?
Right now, Natron has its focus set on AI models and data storage centers, which consume hefty amounts of energy. In 2023, the MIT Technology Review reported that one AI model can emit more than 626,00 pounds of carbon dioxide equivalent. 
“We expect our battery solutions will be used to power the explosive growth in data centers used for Artificial Intelligence,” said Wendell Brooks, co-CEO of Natron. 
“With the start of commercial-scale production here in Michigan, we are well-positioned to capitalize on the growing demand for efficient, safe, and reliable battery energy storage.”
The fast-charging energy alternative also has limitless potential on a consumer level, and Natron is eying telecommunications and EV fast-charging once it begins servicing AI data storage centers in June. 
On a larger scale, sodium-ion batteries could radically change the manufacturing and production sectors — from housing energy to lower electricity costs in warehouses, to charging backup stations and powering electric vehicles, trucks, forklifts, and so on. 
“I founded Natron because we saw climate change as the defining problem of our time,” Wessells said. “We believe batteries have a role to play.”

“Carbon neutral” Bitcoin operation founded by coal plant operator wasn’t actually carbon neutral
Tumblr media
I'm at DEFCON! TODAY (Aug 9), I'm emceeing the EFF POKER TOURNAMENT (noon at the Horseshoe Poker Room), and appearing on the BRICKED AND ABANDONED panel (5PM, LVCC - L1 - HW1–11–01). TOMORROW (Aug 10), I'm giving a keynote called "DISENSHITTIFY OR DIE! How hackers can seize the means of computation and build a new, good internet that is hardened against our asshole bosses' insatiable horniness for enshittification" (noon, LVCC - L1 - HW1–11–01).
Tumblr media
Water is wet, and a Bitcoin thing turned out to be a scam. Why am I writing about a Bitcoin scam? Two reasons:
I. It's also a climate scam; and
II. The journalists who uncovered it have a unique business-model.
Here's the scam. Terawulf is a publicly traded company that purports to do "green" Bitcoin mining. Now, cryptocurrency mining is one of the most gratuitously climate-wrecking activities we have. Mining Bitcoin is an environmental crime on par with opening a brunch place that only serves Spotted Owl omelets.
Despite Terawulf's claim to be carbon-neutral, it is not. It plugs into the NY power grid and sucks up farcical quantities of energy produced from fossil fuel sources. The company doesn't buy even buy carbon credits (carbon credits are a scam, but buying carbon credits would at least make its crimes nonfraudulent):
https://pluralistic.net/2023/10/31/carbon-upsets/#big-tradeoff
Terawulf is a scam from top to bottom. Its NY state permit application promises not to pursue cryptocurrency mining, a thing it was actively trumpeting its plan to do even as it filed that application.
The company has its roots in the very dirtiest kinds of Bitcoin mining. Its top execs (including CEO Paul Prager) were involved with Beowulf Energy LLC, a company that convinced struggling coal plant operators to keep operating in order to fuel Bitcoin mining rigs. There's evidence that top execs at Terawulf, the "carbon neutral" Bitcoin mining op, are also running Beowulf, the coal Bitcoin mining op.
This is a very profitable scam. Prager owns a "small village" in Maryland, with more that 20 structures, including a private gas station for his Ferrari collection (he also has a five bedroom place on Fifth Ave). More than a third of Terawulf's earnings were funneled to Beowulf. Terawulf also leases its facilities from a company that Prager owns 99.9% of, and Terawulf has *showered * that company in its stock.
So here we are, a typical Bitcoin story: scammers lying like hell, wrecking the planet, and getting indecently rich. The guy's even spending his money like an asshole. So far, so normal.
But what's interesting about this story is where it came from: Hunterbrook Media, an investigative news outlet that's funded by a short seller – an investment firm that makes bets that companies' share prices are likely to decline. They stand to make a ton of money if the journalists they hire find fraud in the companies they investigate:
https://hntrbrk.com/terawulf/
It's an amazing source of class disunity among the investment class:
https://pluralistic.net/2024/04/08/money-talks/#bullshit-walks
As the icing on the cake, Prager and Terawulf are pivoting to AI training. Because of course they are.

How AI is Shaping the Future of Democratic Dialogue
New Post has been published on https://thedigitalinsider.com/how-ai-is-shaping-the-future-of-democratic-dialogue/
How AI is Shaping the Future of Democratic Dialogue
In today’s politically polarized world, finding common ground on complex social and political issues is becoming increasingly challenging. As societies grow more diverse, disagreements on crucial matters like climate change, immigration, and economic policy have only extended. Bringing people together to find consensus on complex issues often requires time, resources, and a level playing field where all voices can be heard.
Recent advances in artificial intelligence have brought new possibilities for technology to assist in facilitating complex dialogues on divisive topics. AI-powered large language processing (NLP) models, for example, have grown sophisticated enough to interpret complex language and discern differences in sentiments and perspectives. Moreover, AI systems are being designed with features like real-time sentiment analysis, bias detection, and adaptive feedback. These abilities make them especially suited to assist in facilitating fair and balanced discussions.
This potential has caught the attention of Google DeepMind researchers to explore the promise of AI in facilitating civil discourse. Inspired by the ideas of philosopher Jürgen Habermas, they’ve created the “Habermas Machine” (HM), a tool for supporting civil discourse and helping groups discover shared values. The article examines the question: Can AI really help us find common ground? It also looks at how the Habermas Machine (HM) can facilitate democratic deliberation.
The Habermas Machine
The Habermas Machine is an AI tool designed to analyze individual opinions and create a unified group statement. The machine works like a “caucus mediation.” Participants start by sharing their thoughts. The AI then combines these into a draft statement. Next, participants review this draft and provide critiques. The AI uses its input to generate a revised statement that seeks to gain broader agreement, capturing both majority views and minority critiques.
This machine employs two specialized LLMs for this task. The first is a generative model that creates statements reflecting diverse views of the group. The second is a personalized reward model that evaluates these statements based on how likely each participant is to agree with them. The generative model is refined using supervised fine-tuning, while the reward model is iteratively enhanced based on the reward signals
The machine was tested with over 5,000 participants from across the UK. Some joined through a crowdsourcing platform, while others were recruited by the Sortition Foundation, a nonprofit organizing citizens’ assembly. Participants were divided into groups, and testing took place in two phases. First, the machine summarized collective opinions. Then, it mediated between groups to help identify common ground.
The Promise of AI in Uncovering Common Ground for Democratic Dialogue
The study highlights AI’s potential to find common ground in democratic dialogue. One key finding was that AI-mediated discussions led participants to shift toward shared views. Unlike unmediated discussions, which often reinforced existing beliefs, AI helped participants reconsider their positions, drawing them closer to a middle ground. This ability to encourage alignment shows that AI could be a valuable tool for dealing with complex and divisive issues.
The study also revealed that both participants and independent judges rated AI-generated statements more favorably than those produced by human mediators. They found the AI’s statements to be more precise, more informative, and fairer. Importantly, the AI did not merely amplify majority opinions; it also gave weight to minority viewpoints. This feature helped prevent the “tyranny of the majority” and ensured that dissenting voices were heard. The inclusion of these dissenting views is crucial, especially in sensitive debates, as fair representation helps prevent misunderstandings and encourages balanced discussions.
Real-World Applications of AI in Deliberative Democracy
The implications of AI-mediated deliberation are significant for real-world scenarios. For example, AI can enhance policy discussions, conflict resolution, contract negotiations, and citizens’ assemblies. Its ability to foster balanced dialogue makes it a valuable tool for governments, organizations, and communities seeking to address complex issues involving diverse stakeholders.
To test the model’s effectiveness in a practical setting, researchers organized a virtual citizens’ assembly with a representative sample of UK residents. This assembly focused on divisive topics such as immigration policy and climate action. Following AI-mediated discussions, participants showed a noticeable shift toward consensus, with no AI bias influencing their opinions. These findings highlight how AI mediation can potentially guide collective decision-making on critical social issues while minimizing bias.
Limitations and Ethical Considerations
While AI mediation shows great promise, it has notable limitations. For instance, the AI model used in this study lacks fact-checking capabilities, which means it relies heavily on the quality of input from participants. Moreover, AI-assisted deliberation requires careful design to avoid harmful or unproductive discourse. Another important consideration is the ethical role of AI in democratic processes. Some individuals may be cautious of using AI in political discussions, fearing that algorithms could unintentionally influence outcomes. Therefore, ongoing oversight and a clear ethical framework are essential to guarantee that AI is used in ways that respect democratic values.
The Bottom Line
Researchers at Google DeepMind have emphasized that AI has the potential to transform democratic dialogue. They propose that AI tools, like the Habermas Machine, can help individuals find common ground on complex issues. While AI can make conversations more accessible and inclusive, it is crucial to use it responsibly to safeguard democratic values.
If developed thoughtfully, AI could play a crucial role in facilitating collective understanding. It can help address urgent social issues by finding common ground among diverse perspectives. As AI technology advances, models like the Habermas Machine could become vital for navigating the challenges of modern democracy, simplifying and expanding deliberation processes for more extensive and diverse groups.
