Why do algorithms often fail to accurately reflect user preferences?
Algorithms commonly fall short in capturing user preferences because they rely on the assumption that user behavior (revealed preferences) reflects rational choices. This overlooks psychological biases and the limitations of this 95-year-old economic model.
What biases can emerge when algorithms learn from user behavior?
Algorithms may inadvertently perpetuate biases and discrimination present in user behavior. For instance, training algorithms on historical hiring decisions at companies like Amazon revealed gender bias that was not initially apparent in human decisions.
How do algorithms handle conflicting desires and preferences among users?
Algorithms often prioritize immediate rewards (‘wants’) over long-term resolutions (‘shoulds’), leading to a discrepancy between user intentions and actual behavior. An example is users filling their watchlists with highbrow films but ultimately streaming lowbrow shows recommended by algorithms.
Can AI alone address the limitations in algorithm design?
No, AI alone is not sufficient. The article suggests that a paradigm shift is needed in algorithm design. It emphasizes the importance of incorporating behavioral science, expanding the time horizon of observed behavior, and conducting algorithmic audits to identify and rectify biases.
What are the recommendations for improving algorithm design?
To enhance algorithm design, the article proposes various strategies, including expanding the time horizon of observed behavior, incorporating stated preferences, and conducting both algorithmic and external audits. These measures aim to better align algorithms with normative preferences and improve social welfare.
