## The Science Behind Communication
* Poor communication costs $1.2T annually.
* High-quality communication is the single greatest predictor of team performance.
* People retain only 25–50% of what they hear.

## Mehrabian's 7–38–55 Rule
* 7% of meaning comes from spoken words.
* 38% comes from tone of voice (pitch, volume, rhythm).
* 55% comes from body language (posture, eye contact, gestures).

## Active Listening Techniques
* Effective leaders are rated 40% more effective as listeners.
* Key practices: Reflective listening, soft eye contact (60-70% rule), and strategic 2-3 second pausing.

## Body Language & Power Posing
* Open posture signals trust.
* Power posing for 2 minutes can increase testosterone by 20% and lower cortisol by 25%.
* Mirroring and hand gestures significantly increase recall and rapport.

## Emotional Intelligence (EQ)
* EQ predicts 58% of job performance.
* Focus areas: Self-awareness, empathy, emotional regulation (STOP technique), and social skills.

## Cialdini's 6 Principles of Persuasion
1. **Reciprocity**: Give before asking.
2. **Commitment**: Start with small agreements.
3. **Social Proof**: People follow the lead of others.
4. **Authority**: Credibility increases acceptance by 50%.
5. **Liking**: Similarity and warmth build connection.
6. **Scarcity**: Limited availability drives urgency.

## The BLUF Principle for Clarity
* **Bottom Line Up Front**: State the main point first to reduce cognitive load.
* Simple language and focusing on one core idea increases comprehension by 36%.

## Feedback & Storytelling
* The SBI Model (Situation, Behavior, Impact) is the gold standard for feedback.
* Storytelling activates 7 brain regions; stories are 22x more memorable than facts alone.

## Digital Communication & Conflict Resolution
* Digital text lacks 93% of emotional signals; over-communicate warmth.
* Use Nonviolent Communication (NVC) and perspective-taking to reduce workplace conflict.
