Reading Blink Rate as a Social Cue

• Fast blinking is presented as a possible sign of stress; slow blinking may suggest focus.
• The speaker claims blink rate can shift during deception or intense concentration, often without conscious control.
• Rather than judging a person by one blink-rate reading, look for changes from their usual behavior.
• In a presentation, a noticeable increase in audience blinking could be a cue to adjust the topic or approach.

Key takeaway: Treat blink rate as one possible behavioral cue—not definitive proof of stress, focus, or deception.
