Why Defaults Dominate Human Choice
1. Cognitive Ease: Processing trade-offs requires mental energy; defaults offer a zero-effort escape hatch.
2. Implied Endorsement: Users assume designers selected the optimal, safest path.
3. Loss Aversion: Deselecting a pre-checked benefit feels like voluntarily forfeiting value.
Ethical Redesign Guidance:
Switch to Forced Active Choice or provide explicit opt-in checkboxes with symmetric visual weight to eliminate deceptive compliance risks.
