This article examines the growing adoption of AI tools in the performance review process, prompted by JPMorgan Chase & Co.'s formal decision to permit manager use of an internal chatbot for drafting reviews. The author's central argument is that AI-assisted reviews present a genuine tradeoff: potential gains in objectivity, data synthesis, and time efficiency on one side, and risks of dehumanization, sycophancy, reduced credibility, and analytical offloading on the other. Key evidence includes JPMorgan's internal guidelines prohibiting AI from assigning scores or influencing pay decisions, commentary from Wharton professor Peter Cappelli on human cognitive bias and AI credibility gaps, and examples from companies such as KPMG, Shopify, and Rippling, the latter of which markets an automated 90-day employee assessment tool called Talent Signal. HR consultant Nora Jenkins Townson cautions that AI tools require a pre-existing, well-defined performance standard to function effectively. The article concludes that organizational norms around AI in performance management remain unsettled, and that human judgment retains a necessary role regardless of the technology deployed. Key insights: AI can help managers synthesize larger volumes of employee data — such as peer feedback and work submissions — reducing recency bias and cognitive load, but risks reducing employee perception of review authenticity. Chatbots are observed to exhibit sycophantic tendencies, raising concerns that AI-assisted reviews may be overly positive and fail to surface genuine performance issues. Experimental research indicates that when people are given AI tools, they tend to offload cognitive analysis to the technology, which in a performance review context could degrade the quality of managerial judgment rather than augment it. Practical takeaways: JPMorgan Chase's approach — permitting AI for drafting assistance while prohibiting its use in scoring, pay, and promotion decisions — represents one organizational model for drawing boundaries around AI involvement in performance evaluation. Organizations such as KPMG and Shopify have incorporated AI utilization itself as a performance review criterion, signaling a shift in how AI competency is being formally recognized within evaluation frameworks.
