Reaffirming the Core Principles of Psychology

Principle 1: Behavior has causes
→ Even behavior that appears impulsive is the product
  of biological, psychological, and social factors

Principle 2: Both nature and nurture matter
→ Nature vs. Nurture → now understood as Nature AND Nurture
→ Genes represent possibilities; the environment determines
  which possibilities are realized

Principle 3: Scientific method is what separates knowledge from myth
→ Randomized controlled trials > individual case studies > intuition

Principle 4: Humans are vulnerable to cognitive biases
→ We need habits of mind that question System 1's rapid judgments

Psychology in Relationships

Attraction and Liking

Proximity effect:    the closer we are to someone, the more we like them
Mere exposure effect: repeated contact increases liking
Similarity:          we are drawn to people who share our values and traits
Reciprocity:         we tend to like people who like us

Sternberg's Triangle of Love:
→ Passion + Intimacy + Commitment = Consummate love
→ The balance of these three components determines relationship quality

Conflict Resolution

Gottman's research — the Four Horsemen that predict relationship breakdown:
1. Criticism:    attacking character or personality
2. Contempt:     sarcasm, cynicism, eye-rolling
3. Defensiveness: self-justification, counter-attacking
4. Stonewalling: emotional withdrawal and shutdown

→ Contempt is the most toxic of all
→ Replace criticism with "I" statements that express your own feelings

Psychology in the Workplace

Motivation

Intrinsic vs. extrinsic motivation:
→ Excessive external rewards can reduce intrinsic motivation
  (the overjustification effect)

Psychological safety (Amy Edmondson):
→ The shared belief that the team is safe for interpersonal risk-taking
→ A prerequisite for innovation and learning
→ Google's Project Aristotle: the #1 factor in high-performing teams

Flow (Csikszentmihalyi):
→ Peak productivity when challenge matches skill level
→ Requires clear goals + immediate feedback

Decision-Making

Preventing groupthink:
→ Assign a devil's advocate
→ Deliberately seek out diverse perspectives
→ Use anonymous voting

Overcoming confirmation bias:
→ Test the opposite hypothesis ("What if my idea is wrong?")
→ Premortem: vividly imagine the project has failed — what went wrong?

Psychology and Health

Stress and the body:
Selye's General Adaptation Syndrome (GAS):
Alarm → Resistance → Exhaustion

Chronic elevated cortisol → suppressed immune function, impaired memory

Psychoneuroimmunology:
→ Mental states directly influence immune function
→ Positive emotions → increased NK cell activity

Building resilience:
→ Cultivate a strong social support network
→ Find meaning in adversity (logotherapy)
→ Practice mindfulness

Closing Thoughts

Psychology is a tool for understanding what it means to be human.

What psychology can give you:

Self-understanding:
→ Grasp the causes of your own emotional and behavioral patterns
→ Recognize your capacity for change

Understanding others:
→ Judge less
→ See the context behind behavior

Better decisions:
→ Recognize cognitive biases → reason more clearly
→ Understand group dynamics → be a more effective team member

Resilience:
→ Turn stress and adversity into opportunities for growth
→ Put scientifically validated happiness strategies into practice

Understanding others is, ultimately, a journey toward understanding yourself.
