What Are Thought Experiments?
Thought experiments are hypothetical scenarios designed to help us explore ideas, test principles, and examine our reasoning processes. Unlike real experiments, they take place entirely in our minds, but they can reveal important insights about how we think and what we believe.
In critical thinking, thought experiments help us:
- Uncover hidden assumptions: Reveal beliefs we didn't know we held
- Test moral and logical frameworks: See how our principles apply in edge cases
- Practice reasoning: Develop skills in a safe, low-stakes environment
- Explore complex issues: Break down complicated problems into manageable parts
- Challenge intuitions: Discover when our gut reactions might mislead us
Experiment 1: The Hiring Dilemma
🤝 Testing Fairness and Bias Recognition
The Scenario
You're the hiring manager at a tech company. Two candidates have identical qualifications, experience, and interview performance. However:
- Candidate A: Alex, graduated from an elite university, has a polished LinkedIn profile, comes from a well-connected family
- Candidate B: Jordan, graduated from a state school, grew up in a working-class family, was the first in their family to attend college
The Questions
Step 1: Who would you be more likely to hire? Be honest with your initial reaction.
Step 2: What factors influenced your choice?
Step 3: How would you justify this decision to someone who chose differently?
Step 4: Now consider: What if the backgrounds were reversed but everything else stayed the same?
Experiment 2: The Autonomous Vehicle Dilemma
🚗 Modern Ethics and Decision Frameworks
The Scenario
You're designing the ethical framework for autonomous vehicles. The car's AI must make split-second decisions in unavoidable accident scenarios. Consider these situations:
Scenario A
Unavoidable accident. The car can either:
- Continue straight: Kill 5 jaywalkers
- Swerve right: Kill 1 person on the sidewalk
Scenario B
Brake failure. The car can either:
- Hit a group of elderly people (5 people)
- Swerve and hit a child (1 person)
Scenario C
System malfunction. The car can either:
- Protect the passenger (certain death to 3 pedestrians)
- Sacrifice the passenger (save the 3 pedestrians)

Experiment 3: The Misinformation Challenge
📰 Information Evaluation in the Digital Age
The Scenario
You're scrolling through social media and see a post claiming: "Scientists discover that drinking coffee reduces cancer risk by 50%." The post has 10,000 shares and many positive comments. However, you also see conflicting information elsewhere.
Information Sources
Social Media Post
Viral post with impressive-looking infographic, shared by a "wellness influencer" with 100K followers. No scientific citations.
News Article
Article from a health website with the headline "Coffee May Help Fight Cancer." Mentions a single study but provides few details.
Scientific Paper
Original research paper showing a correlation in 200 participants over 6 months. Study funded by a coffee company.
Meta-Analysis
Review of 50 studies showing mixed results: some positive, some negative, many inconclusive. Published in peer-reviewed journal.
Critical Evaluation Exercise
Apply these critical thinking tools:
- Source Credibility: Rank these sources from most to least reliable. Why?
- Confirmation Bias Check: How does your existing opinion about coffee affect your evaluation?
- Scientific Method: What would better evidence look like?
- Probabilistic Thinking: What's the likelihood this claim is true given all information?
- Occam's Razor: What's the simplest explanation for the conflicting information?
Experiment 4: The Prediction Challenge
🔮 Testing Probabilistic Thinking and Overconfidence
The Scenario
You've been asked to make predictions about various events. For each prediction, you must:
- Give a probability estimate (0-100%)
- Provide your reasoning
- Consider what could make you wrong
Prediction Challenges
Make Your Predictions:
1. Personal Prediction: What's the probability you'll exercise at least 4 times next week?
Consider: Your past behavior, current schedule, motivation level, potential obstacles
2. Weather Prediction: What's the probability of rain in your area this weekend?
Consider: Current weather forecast, seasonal patterns, forecast accuracy
3. Technology Prediction: What's the probability that AI will significantly impact your job within 5 years?
Consider: Current AI capabilities, your industry, adoption rates, definition of "significant impact"
4. Economic Prediction: What's the probability that your local housing market will be higher in 2 years?
Consider: Current trends, economic factors, historical patterns, local conditions
5. Social Prediction: What's the probability that you'll still be friends with your closest friend in 10 years?
Consider: History of friendship, life changes, geographic factors, personal growth
Experiment 5: The Value Comparison Challenge
⚖️ Exploring Hidden Values and Assumptions
The Scenario
You have a limited budget and must choose how to allocate resources. Each option will help people, but in different ways. Consider these trade-offs:
Option A: Local Impact
Fund after-school programs in your city that will help 100 at-risk children improve their grades and life prospects.
Option B: Global Impact
Provide malaria nets that will save the lives of approximately 10 children in developing countries.
Option C: Future Impact
Fund research that has a 10% chance of preventing a disease that could kill 1,000 people in 20 years.
Option D: Immediate Impact
Provide food and shelter for 50 homeless individuals in your community for one month.
Value Exploration Questions
Reflect on these questions:
- Which option did you instinctively choose? Why?
- How do you weigh local vs. global impact?
- Is saving lives more important than improving lives?
- How do you factor in certainty vs. uncertainty?
- Does geographic or cultural distance affect your decision?
- How do you compare immediate vs. future benefits?

Self-Assessment Questions
Remember: The goal isn't to get the "right" answers, but to become more aware of how you think and to develop more systematic approaches to complex decisions.
