Halo Effect

One strong first impression changes how users judge everything else. Positive halo lifts trust. Negative halo creates horn effect.

Goal

• Strengthen positive halo triggers.
• Remove horn effect risks.
• Prioritize polish where perception matters most.

Halo triggers

Horn risks

• Broken first flow.
• Confusing copy.
• Visual inconsistency.
• Placeholder or unfinished UI.
• Poor support signal.

Rules

• Invest most in first 30 seconds.
• Fix first-use bugs before adding secondary polish.
• Test with fresh users.
• Keep quality consistent across adjacent flows.
• Do not rely on users discovering value later.
