The exact text we saved

This is the version exactly as it was saved, character for character. The SHA-256 hash below is a 64-character code worked out from that text. Run the same text through SHA-256 and you get the same code; change a single letter and the code comes out completely different. Each version also stores the previous version’s hash, which chains them together so no version can be swapped out quietly.

headline: Which is better? Matching effect on feedback content and source: Gen AI vs. human leaders in driving work engagement
dek: Purpose Generative artificial intelligence (Gen AI; e.g. ChatGPT, DeepSeek) is increasingly being integrated into performance feedback systems in service organizations, operating alongside human leaders as a dual-source feedback mechanism. Yet the effects of Gen AI feedback on employee work engagement remain unclear. This study addresses the central question of whether and how the matching between feedback source (Gen AI vs. human leaders) and feedback content (positive vs. negative) differentially influences em…
gain_title: In three scenario experiments with 736 valid responses, employees showed higher work engagement when Gen AI delivered negative feedback and human leaders delivered positive feedback.

gain_reading: In three scenario experiments with 736 valid responses, employees showed higher work engagement when Gen AI delivered negative feedback and human leaders delivered positive feedback.
gain_evidence: Gen AI paired with negative feedback and human leaders paired with positive feedback form complementary pairings that more effectively enhance employee work engagement

quick_read: Three scenario-based experiments with a pooled 736 valid responses tested how the source of performance feedback (generative AI or a human leader) and its content (positive or negative) combine to shape employee work engagement. The matching effect was significant: Gen AI delivering negative feedback and human leaders delivering positive feedback produced the strongest engagement.

The finding matters for service organizations that are adding Gen AI, such as ChatGPT or DeepSeek, to feedback systems that run alongside human managers. The results suggest the two sources have complementary strengths rather than one simply replacing the other.

The researchers traced the effect to two kinds of motivation, promotion focus and prevention focus, and found that self-efficacy changed how strong the effect was. All three studies used scenarios rather than live workplaces, so they measure responses to described situations.
limitation: The evidence comes from scenario-based experiments rather than observed workplace feedback, so it reflects responses to described situations.
tag: Evidence-backed gain
key_points: The research combined three scenario-based experiments with 736 valid responses in total. | It tested feedback source (Gen AI or human leader) against feedback content (positive or negative). | Gen AI plus negative feedback, and human leaders plus positive feedback, were the pairings that best raised work engagement. | Promotion-focused and prevention-focused regulation mediated the effect. | Employee self-efficacy moderated the effect. | The authors build on signaling theory and regulatory focus theory and cite the dehumanized nature of Gen AI as part of the explanation.
rundown: The study responds to the spread of Gen AI in performance feedback in service organizations, where it increasingly works alongside human leaders as a second source of feedback. The authors say the effect of that AI feedback on employee work engagement had been unclear.

Using three scenario-based experiments, they compared who gives the feedback with whether it is positive or negative. The best results came from complementary pairings: AI for negative feedback and human leaders for positive feedback.

Further analyses showed that promotion-focused and prevention-focused regulation explained the effect, and that self-efficacy moderated it. The authors offer practical guidance for designing dual-source feedback systems that optimize employee engagement.
