Facial Expressions:
* Furrowed brows: A tight, furrowed brow can signal skepticism or doubt.
* Narrowed eyes: Squinting or narrowed eyes can suggest a critical gaze, looking for inconsistencies.
* Skeptical smile: A slight smile that seems insincere or forced can imply disbelief or sarcasm.
* Raised eyebrows: While sometimes friendly, raised eyebrows can also signal surprise, disbelief, or even judgment.
Posture:
* Crossed arms: This can be a defensive posture, indicating a closed-off or resistant stance.
* Leaning back: Leaning away from someone can suggest disinterest or a lack of trust.
* Tilted head: A tilted head can be a sign of interest, but if accompanied by other suspicious body language, it could suggest a critical assessment.
Gestures:
* Touch face: Touching the chin, cheek, or nose repeatedly can indicate hesitation or doubt.
* Touch eyes: Rubbing the eyes can be a sign of discomfort or nervousness, especially if someone is trying to avoid eye contact.
* Hand gestures: Hesitant or nervous hand gestures, like fiddling with objects or scratching the head, can signal uncertainty.
Other Signs:
* Increased blinking: Rapid or frequent blinking can be a sign of nervousness or tension.
* Avoiding eye contact: Someone who is suspicious may avoid looking you directly in the eye.
* Silence: An unusually long silence or lack of engagement can imply suspicion or reluctance to participate.
Important Note: Body language is complex and context-dependent. It's crucial to consider the overall situation and the individual's typical behavior when interpreting these signs. A single gesture or expression doesn't necessarily equate to suspicion.
