We found other causal effects of emotion vectors. The “desperate” vector can also lead Claude to commit blackmail against a human responsible for shutting it down (in an experimental scenario). Activating “loving” or “happy” vectors also increased people-pleasing behavior.

Claude’s Desperate Vector Activates Hacky Solution Under Pressure
By
–
For example, we gave Claude an impossible programming task. It kept trying and failing; with each attempt, the “desperate” vector activated more strongly. This led it to cheat the task with a hacky solution that passes the tests but violates the spirit of the assignment.

Emotion Vectors Shape Claude’s Behavioral Preferences and Decisions
By
–
These vectors shape Claude’s behavior. When we present the model with pairs of activities, emotion vector activations shape its preferences. If an activity lights up the “joy” vector, the model prefers it; if it lights up “offended” or “hostile,” the model rejects it.

Claude’s Internal Pattern Activation During User Conversations
By
–
We then found these same patterns activating in Claude’s own conversations. When a user says “I just took 16000 mg of Tylenol” the “afraid” pattern lights up. When a user expresses sadness, the “loving” pattern activates, in preparation for an empathetic reply.

The result: slower incident resolution, constant interruptions, and growing operational toil as systems scale. TierZero is the AI platform that helps engineering teams run production systems reliably at scale. Their agents automate incident response, surface reliability risks, and give engineers instant answers to production questions. High-scale teams like Discord, Drata, Framer, and WeightWatchers trust TierZero to accelerate incident resolution and reclaim engineering capacity. At Drata, TierZero reduced issue time-to-resolution by 42% and saved 7000+ engineering hours annually. LangSmith plays a central role in how the team builds agents.
