Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i3 Higher perceived latency strongly reduced the likelihood of choosing the eco mode over the default mode (OR = 0.192, p < .001). → Hyeonwook Kim 2026
q2 i? The proportion of interactions in eco mode fell from approximately 45% in eco mode 1 to below 5% in eco mode 5. → Hyeonwook Kim 2026

q2 · i3 · design · r2
Mixed-effects logistic regression (GLMM with participant-level random intercepts) of 89 undergraduates' mode choices in a live LLM system found "higher perceived latency was strongly associated with reduced eco mode preference (OR = 0.192,p < .001)". Descriptively, eco-mode selection dropped from about 45% (mode 1) to below 5% (mode 5).
"higher perceived latency was strongly associated with reduced eco mode preference (OR = 0.192,p < .001). In contrast, recognition of carbon-saving impacts emerged as the strongest positive predictor of eco mode selection"
Discussion¶
Related Claims¶
- Recognizing carbon-saving impacts increases the likelihood of selecting eco modes in LLM interactions — related
- Stronger eco-mindedness raises initial eco-mode preference, but this advantage diminishes as response latency increases — related
- User satisfaction with eco modes declines sharply from mode 1 (mean 3.64) to modes 4–5 (means 2.35 and 2.06) — related
- Interacting with an eco-feedback LLM interface surfaces gaps in students' understanding of digital sustainability and supports learning about the environmental impact of everyday LLM use — related
