People Can Accurately Predict Behavior of Complex Algorithms That Are Available, Compact, and Aligned
This paper introduces the ACA theory (Available, Compact, Aligned) which demonstrates that users can accurately predict the behavior of even complex algorithms when these three criteria are met. An experiment with 1250 participants predicting social media algorithm behavior shows significantly higher accuracy (85% for ACA vs. 54% for non-ACA) when algorithms adhere to ACA. This framework offers a pathway to designing predictable and trustworthy AI systems without sacrificing performance, enhancing user agency in human-AI interaction.

Availability: Recognizing the Algorithm's Purpose
Availability, drawing from availability bias, captures how easily an algorithm's underlying concepts come to mind for a user. This is influenced by the salience and prior exposure to these concepts, determining whether the algorithmic inputs and objectives are expected and recognizable.
Enterprise Example: For a customer support AI, if its ranking logic prioritizes "urgency" based on keywords visible in chat (e.g., "urgent," "problem," "help now"), this concept is highly available to human agents. If it ranks based on a hidden, complex sentiment score that doesn't visibly correlate with user language, it's less available.
Compactness: Integrating Concepts into a Mental Model
Compactness refers to whether an algorithm's behavior can be synthesized into a single cohesive cognitive concept or a small number of unified concepts. This criterion anchors on cognitive chunking, where smaller units of information are recoded into larger, familiar units, simplifying the mental model.
Enterprise Example: An inventory management AI that sorts items by "sales velocity" (a unified concept combining recent sales and stock levels) is compact. If it sorts by a diffuse combination of "warehouse aisle number - supplier ID + last order date / item weight," it would be non-compact and hard to mentally model.
Alignment: Matching Human and Algorithm Execution
Alignment tests whether the algorithm's execution of its concept agrees with the person's understanding and expectation of that concept. This is crucial for accurate predictions; if the user's mental model of a concept (e.g., "customer satisfaction") diverges from the algorithm's operationalization, predictions will be inaccurate.
Enterprise Example: A fraud detection AI that flags "suspicious activity" is aligned if human users broadly agree with what constitutes "suspicious" based on the AI's flags. If the AI consistently flags legitimate transactions due to an overly sensitive or miscalibrated internal threshold, it fails alignment, leading to distrust and manual overrides.

Designing Predictable Social Media Algorithms
Current social media algorithms often lead to user confusion due to lack of compactness and alignment in their "engagement" operationalization. By focusing on making algorithm concepts available, compact, and aligned, designers can create systems that are both powerful and inherently understandable. This framework encourages building 'concept-based' AI that aligns with human cognition, fostering trust and agency.
"Our theory provides some potential interventions towards this problem. We hypothesize that much of the confusion comes from users not understanding how the nebulous concept of “engagement” is operationalized."
This approach allows for higher-complexity algorithms that achieve specific goals (like personalized recommendations or content filtering) while remaining transparent and predictable to end-users.
