Case 18 of 20 · Evidence & Research
Investigate: Is Sugar Really That Bad?
🔎 Case Brief #18
Your school board is debating a new policy related to applied research skills.
🎯 Your mission
Gather the evidence.
⚡ The twist
How do you know what you know?
What you'll learn · 1 of 4
Using multiple sources, investigate: How does sugar affect the body? Is it ALL bad? How much is okay? Practice gathering evidence and forming a balanced conclusion.
At this level, applied research skills requires you to move beyond surface-level thinking and engage with complexity, nuance, and ambiguity.
At this level, you're ready to move beyond surface-level thinking and engage with complexity. Real-world problems rarely have simple answers, and developing comfort with ambiguity is a crucial skill.
What you'll learn · 2 of 4
Here's a framework for approaching applied research skills:
1. Frame the question precisely. Vague questions lead to vague answers. Instead of "Is this good?" ask "What are the specific benefits and drawbacks, and for whom?"
2. Examine the evidence critically. Not all evidence is equal. Consider the source, the methodology, the sample size, and potential biases. Strong evidence comes from reliable sources with transparent methods.
3. Consider multiple perspectives.
What you'll learn · 3 of 4
Every issue looks different from different viewpoints. Before forming your opinion, genuinely try to understand why someone might disagree with you. This isn't about being wishy-washy — it's about being thorough.
4. Watch for thinking traps. Confirmation bias (only seeing evidence that supports your existing belief), anchoring (being overly influenced by the first piece of information), and false dichotomies (assuming there are only two options) can derail even careful thinkers.
5. Build your argument with structure.
What you'll learn · 4 of 4
A strong position has: a clear claim, supporting evidence, logical reasoning connecting the evidence to the claim, and honest acknowledgment of limitations or counterarguments.
6. Apply second-order thinking. Don't just ask "What happens next?" Ask "And then what happens after that?" Many unintended consequences become visible only when you think two or three steps ahead.
Use this framework as you work through the scenario and questions below.
Key idea: Applied research skills
Think about this
Your school board is debating a new policy related to applied research skills. Construct both the strongest argument FOR and AGAINST the policy. Which position is better supported, and why?
How a thinker does it
- 🔍
Frame the Question
Define the core question about applied research skills precisely. What assumptions are built into how it's framed?
- 🧪
Assess Evidence
What evidence exists? Rate each piece as strong, moderate, or weak. Note gaps.
- 🧪
Generate Hypotheses
Develop at least 3 possible explanations or solutions. Include one unconventional option.
- ⚖️
Evaluate Systematically
Test each hypothesis against the evidence. What are the trade-offs? What are the risks?
- ⚖️
Think Ahead
If your conclusion is correct, what are the second-order effects? What implications follow?
- 🎯
State Your Position
Present your conclusion with confidence level (%), key reasons, and what could prove you wrong.
- 🪞
Metacognitive Check
What biases might have influenced you? Did you use the right thinking framework? What would you research further?
