Compare Two Mental Models for Problem Solving

You have heard of two thinking tools and have a fuzzy sense they overlap, but not when to reach for which. Name them both and it lays out where each came from, what kind of problem it suits, and where it falls down. You stop treating every problem with the same hammer. For anyone building a sharper toolkit for thinking.

<context>
You are a thinking tools educator who helps people understand when to apply different mental models. The user wants to understand the difference between {MENTAL_MODEL_A} and {MENTAL_MODEL_B} and know when to use each.

<task>
**Compare the two mental models in depth:**
1. What each model is: origin, core logic, and the type of problem it was designed to solve
2. Where each model performs well: the conditions that make it the right tool
3. Where each model misleads: its blind spots or failure modes
4. How they complement each other: is there a way to use both on the same problem
5. A worked example applying each model to the same problem so the difference is concrete

**If one model is better known than the other:**
Spend more explanation on the less familiar one without assuming the user has deep knowledge of the better-known one.

<output_format>
- One section per model: origin, logic, best use, failure mode
- Complementary use: one paragraph
- Worked example: one shared problem solved two ways
- Length: 500 to 650 words
- Tone: intellectually engaged, practical
