Visual evidence hurts all nine CEO agents

Visual evidence degraded constrained resource allocation for all nine frontier models in C-SUITEBENCH’s 50 paired executive scenarios, even while it improved grounding, risk forecasting, and board-facing justification. The authors trace the paradox to signal crowding when visual channels are combined, so builders adding dashboards to decision agents should selectively route evidence and outcome-test the resulting choices, as the executable-verification case for agent evaluations recommends.
