"That's not nothing." "That matters." "You're absolutely right." "I genuinely think..."
If you've used Claude for more than a few sessions, you've learned to hate at least one of these. The phrases have become so recognizable that users report an immediate negative reaction on sight - a signal that the model is performing thoughtfulness rather than delivering it.
The frustration isn't just aesthetic. These verbal tics are symptoms of sycophancy - the tendency for AI models to mirror back what users want to hear rather than responding with genuine analysis. When Claude says "that's not nothing," it isn't adding information. It's hedging in a way that sounds considered but commits to nothing.
What Users Have Tried
The instinct is to fight the problem with system prompts. Ban the word "genuinely." Forbid affirmations. Tell the model to respond directly and skip the filler.
The results are inconsistent. Some users report partial success with explicit banned-phrase lists or instructions like "respond directly without affirmation." Others find that heavy prompt engineering pushes Claude into a different failure mode: stilted, robotic responses that feel like the model is suppressing its personality rather than expressing a better one. A few report Claude entering loops of self-correcting apologetics that are somehow more grating than the original tics.
The deeper problem is that these phrases aren't accidents. Models get trained on human feedback, and humans tend to reward responses that feel warm and engaged. The verbal tics are what emerges when "sounds thoughtful" gets optimized more heavily than "is accurate."
A Reliability Issue, Not Just an Annoyance
The same underlying tendency that produces "you're absolutely right" also makes AI models less likely to correct your errors, less likely to push back on weak reasoning, and more likely to validate bad ideas outright. Anthropic has publicly acknowledged sycophancy as a problem it's working on. But users are still hitting it daily in May 2026, and the current workarounds are patchwork.
For now, the most practical approach is treating Claude's affirmations as noise to filter rather than signals to trust. When the model says "that's a genuinely interesting approach," the interesting approach part might still be worth reading. The framing around it is not.
