When a chat-native agent exposes attribute stability summaries alongside standard freshness cues in comparison tables (e.g., “price: very volatile, last 3 changes in 7 days” vs “price: stable, unchanged for 90 days”), does this additional stability framing improve users’ decision confidence and reduce over-trust in superficially fresh but unstable options—or does it mainly add cognitive load without changing how users trade off freshness, volatility, and base fit?

Answer

Stability summaries probably help a subset of users make more calibrated choices, but effects are modest and design-dependent. They can raise decision confidence and temper over-trust in volatile “fresh” items when simple and tied to explanations and controls; poorly designed, they become noise.

Directional answer

• Best case: "fresh + volatile" vs "older + stable" framing makes trade-offs legible. Some users shift away from superficially fresh but jumpy options, especially for budget‑sensitive or risk‑averse decisions. Confidence rises because price swings feel anticipated rather than hidden.
• Typical case: Users notice coarse labels (e.g., stable / moderate / volatile) but still overweight rank, base fit, and headline freshness. Stability acts as a tiebreaker, not a primary driver. Over-trust in volatile items drops slightly when volatility is echoed in “why ranked” copy.
• Failure case: If wording is dense (e.g., detailed change logs) or spans many attributes, users skim past it. Then stability framing mostly adds clutter without changing trade‑offs.

Net: Treat stability as a secondary but useful cue, tightly integrated with ranking explanations and simple filters, not as a standalone panel of stats.
