untrickable
Immune to deception
Untrickable describes someone who cannot be deceived or fooled.
The word suggests a person too sharp, experienced, or skeptical to fall for manipulation: She's untrickable—every scam artist in town has tried.
The term is informal and emphasizes imperviousness to deception rather than mere caution.
