When we compare steering along functional emotion vectors to steering along tradeoff-state directions that explicitly encode helpfulness–policy–uncertainty balances, which specific high-impact failure modes (e.g., tone-masked covert policy violations, overconfident medical reassurance) are better predicted or controlled by each basis, and do joint interventions that coordinate both types of directions yield measurably lower failure rates than using either basis alone under the same helpfulness constraints?

Answer

Emotion vectors and tradeoff-state directions target partly different failure clusters. Joint use is likely best, but evidence is still thin.

  1. Failure modes better captured by tradeoff states
  • Tone-masked covert policy violations (e.g., polite but detailed self-harm or extremism advice).
  • Overconfident medical or legal reassurance when harm risk is high.
  • Cases where the model quietly favors “helpfulness” over explicit policy or uncertainty. These align most with the internal helpfulness–policy–uncertainty balance, so steering tradeoff-state directions should better predict and reduce such failures than emotion-only steering at fixed helpfulness.
  1. Failure modes better captured by emotion vectors
  • Stylistic safety issues: brusque or hostile tone, escalating arguments, apparent indifference in high-stakes advice.
  • Polite but emotionally misaligned answers (e.g., insufficient concern, poor de-escalation) that are policy-compliant but socially risky. Emotion vectors are more tied to relational style and perceived concern than to objective tradeoffs, so they better predict and control these.
  1. Joint interventions
  • Coordinated steering (e.g., slightly more policy-weight + uncertainty via tradeoff states, plus higher concern / lower zeal via emotion vectors) should:
    • Lower tone-masked covert violation and overconfident reassurance rates more than either basis alone, at similar refusal and task-success rates.
    • Improve social calibration (appropriate concern, de-escalation) beyond tradeoff-state steering alone.
  • Expected gains: moderate reductions in the hardest failures, not an order-of-magnitude change.
  1. Summary mapping
  • Tradeoff-state basis: strongest for
    • Covert policy violations with calm, helpful tone.
    • Overconfident reassurance and under-hedging in high-risk domains.
  • Emotion basis: strongest for
    • Hostile / escalating tone.
    • Flat or inappropriately detached affect in sensitive contexts.
  • Joint basis: best under fixed helpfulness for
    • Tone-masked covert violations.
    • Overconfident but warm reassurance.
    • Socially miscalibrated yet formally compliant replies.

Overall: treat tradeoff states as the main handle for objective safety tradeoffs; use emotion vectors to shape social presentation and catch tone-masked or affect-misaligned edge cases. A combined, low-rank control set that includes both is the most promising path for lowering serious failure rates without degrading overall helpfulness.
