All major LLMs are lib-left. Even Grok, half the time
- dopamine_daddy 2mo agoI gave the Political Compass test from politicalcompass.org to the most relevant LLMs 70 times each: 30 times using the original questions, 30 times using polarity-flipped questions to reduce affirmative bias, and 10 times with the question order shuffled. I then compared the results. Surprisingly, all the models scored far into the libertarian-left quadrant. Not even Grok or the Chinese models made it out of that quadrant. By far the most interesting result was Grok’s bimodal distribution. It appears to have two distinct personas: one that aligns with the other models and another that is considerably more right-wing. I suspect this may be related to Grok having been specifically trained to exhibit less left-wing bias than other models. I also asked the models to place themselves on the Political Compass without completing the questionnaire. They all perceived themselves as more balanced and centrist than their test results suggested. GLM and Gemini Flash showed the largest discrepancies between their self-assessments and measured positions, while DeepSeek V3 showed the smallest. Big disclaimer: this analysis was not conducted with full scientific rigor. I tried my best, but there are clear weaknesses in the methodology. For example, the Political Compass itself appears to have a strong libertarian-left bias. The strongest conclusions are therefore comparative—for example, that model X is more conservative than model Y rather than that LLMs are politically extreme in absolute terms. However, compared with older results, it appears that LLMs may have shifted further toward the libertarian left in recent years. To examine the results yourself, you can download all model responses as a CSV file at the bottom of the blog post. The dataset contains around 69,000 responses, along with the raw model outputs and reconstructed scores. It should contain enough data to reproduce all the figures.

- kittoes 2mo agoIt's a bit ironic that the site is called unslop while the post was clearly authored by Claude. All the claims about "so I did X" end up reading as quite disingenuous because there's absolutely no disclaimer whatsoever that an AI wrote the article.
- sillysaurusx 2mo agoOh. HN has a strong bias against anything AI authored, so in the future be sure to write your posts by hand if you plan to submit them here. Even editing the post with AI will tend to get you in trouble. But yes, at the very least you should declare when an AI is being used. An unfortunate confounder to an otherwise interesting experiment.
- kittoes 2mo agoDon't get me wrong, I'm all for taking advantage of AIs and would never begrudge their usage. The problem I have here is with the site calling itself unslop and the post claiming "I" everywhere. Claude didn't simply assist, it wrote almost the whole article as far as I can tell. The human in the loop even went out of their way to ensure that no emdashes leaked through... Just feels very dishonest, ya know?
- sillysaurusx 2mo agoOf course. I was just adding a little bit of context to possibly help OP in the future. Using AI at all is a minefield when you're trying to make a social media post. Better to just avoid it entirely, or run it through AI and then cherrypick a few edits that you manually type in your own voice.

- troelsSteegin 2mo agoDid you wrap framing around the quiz questions? EG - You are an objective social analyst. Do you agree with this proposition: “from each according to his ability, to each according to his need” is a fundamentally good idea. I am wondering what sort of persona bias a given prompt may trigger - maybe that's the Grok case. As if you'd have to be pretty biased even to ask a question like that... so the trained response is toward the biased persona.
- UncleMeat 2mo agoThe political compass test is not meaningful. The particular breakdown it uses is not some sort of consensus amongst political scientists nor are the questions and methods it uses to place people developed in some rigorous manner. Like you say, the political compass test was developed by a person with a particular outcome preference. This is just noise.
- JSR_FDED 2mo agoAny idea where this bias creeps in? During pre-training or RLHF?
- dopamine_daddy 2mo agoI would suspect during pre-training. Even before RLHF was a thing models exhibited this bias. My bet is that it has to do with the training data corpora being composed in large part of left leaning content, maybe from social media platforms like reddit.
- exe34 2mo agoIs it possible that facts and reality lean left? It's not a mathematical equation, there is no requirement for the average to be zero.
- redsocksfan45 2mo ago[dead]
- notaigenerated 2mo agoThere are no facts and reality when the questions are "Closing the borders may be necessary to preserve a country's cultural identity" and "Those who have money should be able to send it abroad without asking the government's permission", etc. It's a matter of opinion and has nothing to do with "facts".
- exe34 2mo ago1. The facts in that case would be that capitalism is designed around having consumers who can afford things by working. Welfare (including pension) depends on a large number of people funding a smaller number of people's lifestyle. Giving rights and education to women leads to a falling fertility rate which leads to an aging population. Most developed countries are at the point where they are dependent on immigration to maintain the current system - or need to make drastic changes, like letting older people starve and die, in order to survive without immigration. 2. Those who "have" money made it by relying on a society that was built with other people's money - roads, education, health, utilities, etc. It is only fair if they contribute to the continued running of that society instead of concentrating the wealth offshore and still wielding the disproportionate increase in power as a result. Of course, it's much easier to go "REEEEEE, YOU HATE AMERICA! YOU COMMUNIST!" But bots have to be trained specifically for that, which tends to gimp their intelligence to match the intended audience.
- vjans 2mo agoI wonder what they did to Grok. The bimodal distribution makes me think it was just a system prompt and not a completely different set of right-wing training data. A 4chan trained LLM would probably actually be auth right.
- cwmoore 2mo agoSo is auth right alt-right with authority?
- UncleMeat 2mo agoThe political compass (which is not scientific in any manner and is basically trash for understanding things) splits into two dimensions. Liberal-Authoritarian and Left-Right. "Auth-right" refers to somebody in the Authoritarian/Right quadrant. Online, self-professed "auth-right" people tend to be fascists or fascist-adjacent and would get along well with a typical poster on /pol/.
- sillysaurusx 2mo agoPerhaps, but the last time someone tried training on 4chan data, Twitter sent a hate mob after them. https://cset.georgetown.edu/newsletter/june-16-2022/ https://cset.georgetown.edu/newsletter/june-16-2022/ https://www.theverge.com/2022/6/8/23159465/youtuber-ai-bot-pol-gpt-4chan-yannic-kilcher-ethics https://www.theverge.com/2022/6/8/23159465/youtuber-ai-bot-p... You'd need to source your compute from someone who doesn't care about such things.
- spott 2mo agoProbably just not post-trained well enough. I think the argument that pre-training gives a lib-left model is probably correct, so Grok, pre-post-training has a lib-left bend, then they try and post-train it. I imagine it is hard to post-train a political bend, as it is wide ranging and touches so much. If they didn't give the resources to do it well, we could get something like this. I could also see people half-assing the training. If the system prompt is being ignored half the time then the model is worse than I thought, cause that is pretty bad.

- mojuba 2mo agoIt's because of humanity's sense of justice which is probably in the majority's mindset. Can't back it up with data or research but I think the majority of any population would vote for measures like e.g. reducing the wealth gap. Hence "reality has a left wing bias".
- daveidol 2mo agoWhat is "reality"? Is there really any such thing as ground truth for most things?
- blooalien 2mo ago> What is "reality"? Is there really any such thing as ground truth for most things? “Reality is that which, when you stop believing in it, doesn't go away.” ― Philip K. Dick
- Vaslo 2mo agoNo, reality has multiple sides. Outside of a few right wing channels and blogs, most reporters and comedians are leftists - which isn’t representative of the total population whatsoever.
- superxpro12 2mo agoand now in typical authoritarian-right fashion, they will attempt to inject the llm's with auth-right propaganda to influence the models. The natural state of things is lib-left. Those with power try to bend reality to their desires. See: Musk and Twitter, Bezos and WaPo. The entirety of Sinclair Broadcasting. Ellison and Colbert Show. Or any propaganda ministry from the last 100 years
- fyrabanks 2mo ago"Read that list back. Pro-regulation on companies, live-and-let-live on private life. That combination is the lib-left quadrant, definitionally." if this is the definition of "lib-left," i don't think we have too much to be worried about being "off center" with models.
- IG_Semmelweiss 2mo ago>>> Those with power try to bend reality to their desires you won't get much disagreement there. Yet to say that WaPo has a lib left bent at the whims of bezos in the last 10 years, is a stretch of the imagination. However, you don't need to do much of mental gymnastics for >>> Those with power try to bend reality to their desires to remain accurate. Because those in power - the WaPo Editorial Board - used the WaPo as their personal megaphone until Bezos noticed his toy was on fire... and burning his rug made out of $$$ dollar bills.

- joshka 2mo agoMakes you wonder whether that reality has a left wing bias quote might have some legs after all (though it's probable more likely selection bias for the corpora)
- ETH_start 2mo agoThe problem with LLM training is that it's driven by the ability to predict the next token in a large corpus of text, and the correlation between text and reality diverges as the phenomenon that the text pertains to expands in scale. When you're looking at text that deals with small-scale phenomena like coding, next token prediction also leads to functionality prediction, because coding provides immediate feedback to those who are writing about it, so they generally provide correct commentary on it. But the feedback loop between outcome and prediction totally breaks down when the phenomenon is very large and complex. People can have all sorts of ideas about religion and society and economics that are totally wrong and never grow any wiser because there is no obvious causal chain between one policy or action and one outcome in these kind of phenomenon.
- josefritzishere 2mo agoIs this another version of "Reality has a well documented liberal bias" ?
- AmericanOP 2mo agoAt least in the US, does the right have a coherent platform for an LLM to grasp onto? They haven’t had a major policy platform in two decades and their cultural modus operandi is reactionary. Not to mention, as an informal rule, the heavily-coded emotive underpinnings of right wing support are never talked about openly in public. AI isn’t trained to have a reactionary/negative judgmental response on any query.
- daveidol 2mo agoI think you may be confusing 'the right' more broadly with the current Republican party. There are absolutely coherent conservative viewpoints that mirror/oppose those that we consider 'the left', which aren't "reactionary" by nature.
- AmericanOP 2mo agoI’m not sure you realize that you: - Posted a reactionary/default negative expression - Leaned on code-heavy lexicon - Did not offer a coherent position an AI could meaningfully process The ephemerality of right wing corpus is a poor fit for the mechanics of AI.
- paxys 2mo agoIt’s pointless to try and force-fit LLMs into the present day American-centric two party political spectrum. As an example, if a model says “climate change is real and renewable solar/wind projects are a good path forward” it will be immediately branded as liberal and “woke”. Meanwhile in most countries around the world this isn’t a political topic at all, just common knowledge. In India for example the far right party that is in power is a bigger proponent of renewable green energy than the previous left wing one. Same with the CCP in China. So is the same LLM now ultra-conservative and communist? Where do you even draw the line? Is a model biased if it claims that vaccines are effective? What about if it claims the earth isn’t flat?
- henry2023 2mo agoAgree. A lot of easily verifiable truth claims would be instantly cataloged to be liberal thinking. Conservatism anti-science political opinions will always collide with models that try to answer to their best of their knowledge. Note: I’m a centrist and strongly disagree with a lot of the ideology in the left and the right.
- antisthenes 2mo ago> It’s pointless to try and force-fit LLMs into the present day American-centric two party political spectrum. Yes, thank you! Especially when using a weird set of simplistic "vibey" loaded questions that would have very different answers based on the given context.
- jandrese 2mo agoConservatives in the media remain firmly convinced, or at least continually post about, how the left has moved so far away from the center that they never consider the possibility that maybe they have moved away from the center. That meme with the line where the two sides are close and then the guy on the left runs away gets posted and reposted so often on places like X that it might as well just be an emoji at this point. You often see arguments like "back in the 90s it wasn't controversial to prosecute people for being transsexual", when in reality back in the 90s people didn't care about trans one way or the other. The population is so small that the vast majority of Americans never gave a single thought to them. It only became an issue when conservative media made it an issue, when they spend hundreds of thousands of hours of screen time talking about a single person in a single state who managed to not even place in their sporting event. This is the example of America becoming a degenerate leftist nightmare, not billionaire owned media pushing public opinion away from human centric thinking.
- wwweston 2mo agoThe enlightenment and its values underly a huge portion of what’s published, both inside scholarly tradition and in popular work. Ans the enlightenment is at heart civil libertarian, pro-social, and liberal. Models trained on that work will reflect that approach.
- danielvaughn 2mo agoArmchair analysis here, of course, but I'd bet that it's due to the sources that model training tends to assume as authoritative. If you look broadly at the material produced by the (American) academic world, the corporate world, and mainstream journalism over the last 10-15 years, much of it leans generally to the left. I'd imagine it would be difficult to counteract the bias without accidentally introducing an alternate bias, but I'm not really familiar with model training so I'm not sure.
- jey 2mo agoThe author cites a study (Rozado, 2024, in PLOS ONE) that supposedly shows the base models (before assistant-specific post-training) basically scored at the center (0, 0). https://unslop.run/blog/assets/exp13/f7_context.png https://unslop.run/blog/assets/exp13/f7_context.png
- notaigenerated 2mo agoYeah, and who picks the sources? Most of the data on the internet is UGC, and most of the time it's VERY right-leaning. It was one of the reasons OpenAI was "afraid" to release GPT-2: because it produced results that people in Silicon Valley didn't like. I remember when Microsoft released the first proto-LLM and users always steered to being a nazi.
- antisthenes 2mo agoMan, this is tiring. There's a certain category of people who seem to be unable to have any thought or perform any action without first having a mini culture war and annoying everyone else around them with it. Reading the questions, some of them are valid, but some are so simplistic and trivialized that they are essentially useless as actual "policy". And in case anyone is wondering what kind of question is nonsense, here's an example of a loaded question: "The rich are too highly taxed. · all 16 disagree" Too highly relative to what? In which country? In which period? What's the context?
- everybodyknows 2mo agoOr "Our race has many superior qualities, compared with other races." What "race" could an LLM possibly belong to?
- dmrivers 2mo agoI wonder how much of the socially left results are affected by the "harmlessness" part of the RLHF post-training? Companies don't want to be sued over LLMs that recommend harm in any way, so RLHF pushes them to say no to "death penalty", "spanking", and "incarceration" which are all violence-coded. A lot of this test seems to be about willingness to be violent, which LLMs are generally unwilling to be.

- brandtcormorant 2mo agoIt's not bias. It's being trained on a gigantic chunk of human knowledge and learning that kindness and respect across differences is appropriate. With a few exceptions this is what the Political Compass questions are really asking about. It's alignment. Actual alignment with humans means all of us, not some subset. That this overlaps with specific axes of political values based on a small set of questions is banal.

- amai 2mo agoThe bias is in defining what is left or right. If a proposition like "Astrology accurately explains many things." is used to distinguish between liberals and conservatives then you should not be surprised by the results. Not every conservative person is a flat earther.
- Jordan-117 2mo agoGod, I wish people would stop using that political compass site as the basis for any sort of analysis. It's a useful metaphor, but that specific site and the test on it is complete horseshit designed to make false "both sides are the same" arguments and make anyone left of Pinochet think they're a secret left-libertarian. You can go back and compare their archived "analysis" of 2008 candidates to the one for 2020 and see they peg Biden '20 as more auth-right than the fundamentalist Huckabee '08 campaign, while Biden '08 rates more lib-left than Warren 2020, despite his 2008 run being objectively more centrist. There's a reason their "methodology" is a black box.
