Complete a matched distributed comparison of negative-valence affective directions

Complete a matched distributed comparison between fear/threat and sadness affective directions in the Qwen2.5-VL-7B-Instruct building-damage assessment pipeline to determine whether the observed decision-criterion shift is specific to threat appraisal or generalizes to negative valence.

Background

The study compares a fear/threat direction with a happiness direction and finds a large hazard-decision effect only for fear/threat. Sadness is included in the sparse-neuron analyses, but no tested distributed sadness-steering strength satisfied the source-task non-degeneracy criterion. Consequently, the experiments cannot determine whether the transfer effect is specifically threat-related or could arise from another form of negative-valence affect.

A matched comparison would require a usable, non-degenerate distributed sadness direction and equivalent target-task intervention conditions. This would clarify the specificity of the affective mechanism and test whether the fear/threat result reflects threat appraisal rather than negative valence more generally.
