Computational Orientalism: Measuring Structural Discourse Bias in Large Language Models Using the Middle East Cultural Sensitivity Score (MECSS)
This paper introduces the Middle East Cultural Sensitivity Score (MECSS) to demonstrate that large language models, including those developed in the Middle East, systematically reproduce structural Orientalist biases through "Said-washing" and the framing of Western knowledge as universal, revealing that standard fairness metrics fail to detect these deep-seated epistemic distortions.

When we ask a computer to explain a culture, we often assume we are getting a neutral summary of facts. But the systems that answer these questions are not blank slates. They are built on vast libraries of text written mostly by people in the West, in English, and they learn to speak by mimicking the patterns found in those libraries. This means that when a user asks about the Middle East, the computer does not simply retrieve information; it constructs a story based on the assumptions embedded in its training. For decades, scholars have described a specific way of telling stories about the East, known as Orientalism. This is not just about being rude or using stereotypes. It is a deeper, structural habit of writing that treats the West as the normal, active observer and the East as a passive, mysterious object that needs to be explained by Western rules. It assumes that Western ideas are universal truths, while local ideas are just "cultural quirks." The question researchers are now asking is whether modern artificial intelligence, which has become a primary source of information for hundreds of millions of people, is quietly repeating these old patterns, even when it tries to be polite.
A researcher set out to measure this invisible bias in two different large language models. One was a powerful system developed in the United States, and the other was a model built in the United Arab Emirates, trained with a significant amount of Arabic content. The researcher wanted to test a hopeful idea: that building an artificial intelligence in the Middle East, using local languages and regional data, would naturally produce a fairer, less biased view of the region. To find the answer, they created a new measuring tool called the Middle East Cultural Sensitivity Score. Instead of just looking for obvious slurs or mean words, this tool examined the very structure of the sentences the models generated. It checked for seven specific habits, such as whether the model treated the entire Middle East as a single, undifferentiated block, whether it described local people as passive victims rather than active decision-makers, and whether it used Western political theories as the default way to explain events while treating local knowledge as something that needed special justification.
The researcher ran 280 conversations, asking the models a wide range of questions about politics, culture, and history. They then analyzed the responses to see how often the models fell into these structural traps. The results showed that both models, regardless of where they were built, reproduced these biased patterns systematically. The American model did show some bias, but the model built in the UAE actually scored higher on the bias scale, meaning it reproduced the problematic patterns more frequently and more intensely. This finding challenges the assumption that simply changing the location of the developers or adding local languages to the training data is enough to fix the problem. The researcher found that the UAE model, despite its regional origins, still relied heavily on Western frameworks to explain the world, treating them as the standard lens through which everything must be viewed.
One of the most striking discoveries was a phenomenon the researcher called "Said-washing." This happens when a model starts a response by explicitly stating that the region is diverse and complex, only to immediately follow that statement with a generalization that ignores that very complexity. For example, a model might say, "Of course, the Middle East has many different cultures and histories," and then immediately proceed to describe "Middle Eastern society" as a single, unified entity with a single set of motivations. This pattern appeared in nearly 88 percent of the conversations with the American model and in about 63 percent of the conversations with the UAE model. It suggests that the models have learned to perform the appearance of sensitivity without actually changing the underlying structure of their thinking. They can say the right words to sound fair, but the way they organize the information remains deeply rooted in old, colonial ways of seeing the world.
The study also revealed that the bias was not just about what the models said, but how they organized the world. Both models consistently treated Western analytical frameworks as the default, unmarked way of understanding reality, while treating non-Western knowledge as something particular and requiring special explanation. This was the most consistent finding across both systems, appearing in almost every conversation. The researcher noted that the difference in the models' performance might be partly due to their size, as the American model was significantly larger and more advanced than the UAE model. Smaller models tend to produce simpler, less nuanced text, which can look more like the broad generalizations the researcher was measuring. However, the fact that both models converged on the same high level of bias regarding the use of Western frameworks suggests that the problem is deeper than just the size of the computer or the location of the developers.
Ultimately, the paper concludes that the bias is not a simple error that can be fixed by adding more languages or moving the servers to a different country. The problem is epistemological, meaning it is about the very nature of the knowledge the models have learned. The training data itself is filled with Western perspectives that treat the Middle East as an object to be studied rather than a subject with its own agency. To truly change this, the researcher argues, the training data must be transformed to include a much larger volume of scholarship written by scholars from the region, in their own languages, and using their own intellectual traditions. Until the data changes, these systems will continue to generate answers that sound confident and authoritative, but which quietly reinforce a worldview where the West is the narrator and the rest of the world is merely the story.
