Two Ways Your Brain Makes Decisions
Understanding fast and slow thinking helps you organize better, convince people faster, and make smarter choices
Meet Your Two Thinking Systems
Scientists discovered that our brains work in two different modes. Think of them like two different gears in a car.
⚡Fast Thinking
Quick. Automatic. Emotional.
This is your gut reaction. It happens instantly without effort. Your fast thinking helps you:
- Recognize faces
- Feel emotions
- Make snap judgments
- React to danger
- Form first impressions
🧠Slow Thinking
Careful. Deliberate. Logical.
This is your reasoning brain. It takes effort and energy. Your slow thinking helps you:
- Solve math problems
- Compare options
- Plan ahead
- Check your work
- Make complex decisions
Real-Life Example
Fast thinking: You see someone you know across the street. You wave instantly.
Slow thinking: You're choosing health insurance. You compare plans, read details, and calculate costs.
The key point: Most of your decisions use fast thinking. Your slow thinking only kicks in when you force it to.
Why Changemakers Need to Know This
Understanding these two systems helps you in every part of civic work:
Better Messages
Connect with people emotionally first. Then give them facts to back it up.
Stronger Organizing
Know when people need time to think versus when to ask for quick action.
Smarter Strategies
Use slow thinking for planning. Use fast thinking to read the room.
Fairer Decisions
Catch your biases. Question your gut reactions when they matter.
What This Means for Your Work
- People make most choices with their fast brain
- Emotions drive action more than facts alone
- Complex decisions need time and thought
- First impressions happen in milliseconds
- Stories stick better than statistics
Using Fast Thinking in Your Work
Fast thinking is powerful. Here's how to use it well:
1. Lead with Stories, Not Stats
People's fast brains love stories. Stories create emotion. Emotion drives action.
Before and After
Less effective: "30% of Houston families struggle with food insecurity."
More effective: "Meet Maria. She works two jobs but still can't always feed her kids. She's one of 300,000 Houston parents facing this choice every day."
2. Make Things Visual
Fast thinking processes images quickly. Use photos, graphics, and symbols.
- Put faces in your materials
- Use colors that mean something
- Create simple icons
- Show before-and-after images
3. Create Simple Choices
Fast thinking hates complexity. Give people clear options.
Making It Easier
Too complex: "There are 47 ways to get involved. Review our 12-page guide."
Just right: "Pick one: Attend an event. Donate $10. Share our post."
4. Use Familiar Language
Fast thinking recognizes patterns. Use words people already know.
- Say "neighborhood" not "census tract"
- Say "get help" not "access services"
- Say "your rights" not "statutory entitlements"
Watch Out For
Fast thinking also creates biases. It makes snap judgments that can be wrong. Always check important decisions with slow thinking.
Using Slow Thinking in Your Work
Some situations need careful thought. Here's when and how:
When to Use Slow Thinking
- Planning campaigns
- Choosing partners
- Setting budgets
- Making policy decisions
- Evaluating results
- Handling conflicts
How to Encourage Slow Thinking
Give Time
Say "Think about this overnight" or "Let's decide next week."
Ask Questions
Use "What if..." and "Have we considered..." to trigger deeper thinking.
Use Checklists
Create lists of questions to ask before big decisions.
Get Input
Other people spot things you miss. Ask for feedback.
Slow Thinking in Action
Situation: Your group wants to support a new policy.
Fast thinking says: "This sounds great! Let's endorse it!"
Slow thinking asks:
- Who benefits? Who might be harmed?
- What are the costs? Who pays?
- Are there unintended consequences?
- What do experts say?
- What do affected communities want?
Tips for Better Slow Thinking
- Write things down
- Sleep on big decisions
- Do research before choosing
- Challenge your assumptions
- Consider the opposite viewpoint
Putting It Together: Real Situations
Here's how to use both systems in common civic situations:
Situation: Running a Community Meeting
Use fast thinking for:
- Creating a welcoming atmosphere
- Reading people's body language
- Sensing when energy is dropping
- Building emotional connection
Use slow thinking for:
- Planning the agenda
- Deciding who speaks when
- Analyzing what you learned
- Planning next steps
Situation: Creating Campaign Materials
Use fast thinking for:
- Choosing powerful images
- Writing emotional headlines
- Picking attention-grabbing colors
- Creating memorable slogans
Use slow thinking for:
- Fact-checking all claims
- Testing messages with focus groups
- Ensuring accessibility
- Measuring effectiveness
Situation: Recruiting Volunteers
Use fast thinking for:
- Making people feel welcome
- Sharing inspiring stories
- Creating immediate opportunities
- Celebrating quick wins
Use slow thinking for:
- Matching skills to roles
- Creating training programs
- Building leadership pipelines
- Evaluating volunteer impact
The Golden Rule
Connect emotionally first. Then provide the logical backing.
People need to feel something before they think deeply about it. Once you've touched their fast brain with emotion, their slow brain will engage to justify the feeling with logic.
Quick Reference Guide
- Recruiting people: Fast brain first (inspiration)
- Planning strategy: Slow brain required
- Writing social posts: Fast brain focus
- Making partnerships: Slow brain essential
- Responding to crisis: Fast brain first, slow brain follows
- Evaluating programs: Slow brain required
Common Mistakes to Avoid
Mistake 1: Facts Without Feelings
Many advocates think data alone will convince people. It doesn't. Lead with emotion and story. Then back it up with facts.
Mistake 2: Forcing Slow Thinking When People Are Tired
Slow thinking takes energy. Don't ask people to make complex decisions at the end of long meetings. Plan important discussions when people are fresh.
Mistake 3: Trusting Your Gut on Everything
Fast thinking creates biases. It makes you see patterns that aren't there. Always check big decisions with slow thinking.
Mistake 4: Making Things Too Complicated
If you need a 20-page document to explain your idea, people's fast brains will reject it. Simplify first. Add details later for those who want them.
Mistake 5: Ignoring Emotions in Planning
Some organizers think emotions don't belong in strategic planning. They're wrong. Emotions drive motivation. Plan for how people will feel, not just what they'll think.
The Biggest Mistake
Trying to be purely logical in civic work. Humans aren't logical creatures. We're emotional creatures who can think logically when we need to. Plan for both systems.
Ready to Practice?
Look at your next campaign message, meeting plan, or volunteer ask. Which brain are you talking to? Are you using both systems effectively?

This article is based on research by Nobel Prize winner Daniel Kahneman, author of "Thinking, Fast and Slow." His work explains how our minds really work—not how we think they work.
Key takeaway: Both thinking systems are valuable. Fast thinking helps you connect, inspire, and act quickly. Slow thinking helps you plan, evaluate, and make wise choices. Master both to become a more effective changemaker.
