"Dr. Lora Aroyo, Senior Research Scientist at Google DeepMind, argues that this assumption no longer holds up. Her research at the intersection of data-centric AI and pluralistic alignment challenges the binary worldview that underpins most AI systems. Instead of seeking a single "gold standard" answer, she advocates for embracing disagreement, diversity, and pluralism as the foundation of more reliable, culturally aware AI."
"In her work, through frameworks like CrowdTruth, GRASP, and datasets such as DICES and DIVE, Aroyo has shown that human variation isn't noise to eliminate. It's the signal that can help AI truly reflect the societies it serves. From Data Quantity to Data Quality In the mid-2000s, the AI community experienced an explosion of progress fueled by one key realization: with enough data, models improve. The now-famous 2009 study demonstrating the power of data quantity marked a turning point for the field."
AI's assumption of a single universal truth limits model understanding and interaction. Human disagreement, diversity, and pluralism supply essential signals rather than noise. Frameworks such as CrowdTruth and GRASP and datasets like DICES and DIVE capture human variation to inform models. Early AI progress prioritized data quantity, producing large but demographically narrow datasets that missed cultural context. Data-centric AI emphasizes data quality, contextual diversity, and data excellence. Rigorous collection, curation, and evaluation must consider whose perspectives and values data encode. Embracing pluralistic alignment and culturally aware datasets yields more reliable, inclusive AI systems.
