The Problem with Making Big Decisions Alone
When you're facing a major decision—whether it's choosing an enterprise software solution, launching a strategic initiative, or restructuring your team—there's a dangerous trap: your own perspective. No matter how experienced you are, you have blind spots. You favor certain types of solutions. You overlook risks that don't naturally occur to you.
Most of us try to compensate by seeking advice, but here's what usually happens: you get polite feedback that doesn't challenge your assumptions, or you get input from people who all think similarly. You end up with validation, not genuine scrutiny.
Lincoln's Secret: Surrounding Himself with People Who Disagreed
Abraham Lincoln had a radically different approach. He deliberately filled his cabinet with rivals and critics—people who had competed against him, who disagreed with his methods, and who weren't afraid to challenge him directly. His Secretary of State, William Seward, had been his chief rival for the Republican nomination. His Secretary of the Treasury, Salmon Chase, actively undermined him while serving in his cabinet.
Why would Lincoln do this? Because he understood that rigorous debate and diverse perspectives led to better decisions. He wanted his ideas stress-tested by people who naturally saw their weaknesses, not cheerleaders who'd rubber-stamp whatever he proposed.
Now you can apply this same approach to your decisions using AI—by creating a custom ChatGPT that simulates a "Team of Rivals" advisory council.
How to Create Your Own Team of Rivals Custom GPT
Here's how to build a custom GPT that gives you the kind of rigorous, multi-perspective analysis Lincoln valued. This takes about 5-10 minutes to set up, and you can use it repeatedly for any major decision.
SETUP STEPS
- Go to ChatGPT and click your profile icon in the top-right
- Select "My GPTs" then click "Create a GPT"
- Click "Configure" at the top to skip the conversation builder
- Give it a name like "Team of Rivals Decision Council"
- In the Instructions field, paste the configuration document (download link provided at the end of this post)
- Set Conversation starters like "Help me evaluate this strategic decision" or "I need multiple perspectives on this initiative"
- Click "Save" and choose whether to keep it private or share with others
The configuration document creates six distinct advisors, each with different personalities, priorities, and ways of thinking. They'll challenge each other—and challenge you—to ensure you've considered all angles.
What Makes This Approach Powerful
Unlike asking ChatGPT a straightforward question, this custom GPT is specifically instructed to generate authentic disagreement. You're not getting six variations of the same perspective—you're getting genuinely different ways of looking at your problem.
The advisors include a data-driven strategist, a pessimistic risk manager, an ethics-focused advocate, a blunt pragmatist, an optimistic visionary, and someone focused on historical precedent. Each one looks for what the others might miss.
How to Use It for Real Decisions
When you open your Team of Rivals GPT, describe your decision or challenge in specific detail. The more context you provide, the better analysis you'll get. Include relevant constraints, stakeholders, resources, and your preliminary thinking.
WHAT YOU'LL GET
Phase 1: Each advisor presents their initial recommendation and concerns—you'll see six different takes on your situation.
Phase 2: The advisors debate each other, questioning assumptions and poking holes in each other's logic. This is where you discover blind spots.
Phase 3: After hearing all perspectives, advisors refine their positions and identify where they can't compromise.
Phase 4: You get final recommendations, including areas of consensus, irreconcilable differences, and implementation considerations.
The whole process typically takes one conversation of 15-30 minutes, depending on the complexity of your decision. You can ask follow-up questions, introduce new information, or ask specific advisors to elaborate on their concerns.
Real Scenarios Where This Works
This approach is particularly valuable for decisions where multiple factors compete: choosing between enterprise software platforms (cost vs. features vs. implementation complexity), deciding whether to pursue a strategic partnership (opportunity vs. risk vs. resource commitment), or planning organizational restructuring (efficiency vs. employee impact vs. cultural change).
It's less useful for straightforward technical questions or situations where there's a clearly right answer. Use it when you need genuine strategic thinking, not just information.
WAYS TO CUSTOMIZE THIS PROMPT
- Adjust the advisors: Modify the six advisor personalities to match your specific domain (add a "technical architect" or "customer advocate" if relevant)
- Change the intensity: Tell the GPT to be more or less confrontational based on your preference
- Add industry context: Include specific information about your industry or organization in the configuration
- Focus the questions: Customize the "Questions to Address" section to match your recurring decision types
The Bottom Line
KEY TAKEAWAY
Lincoln understood that good decisions come from rigorous debate between people who see problems differently. You can replicate this by creating a custom ChatGPT that generates authentic disagreement and diverse perspectives. The result: better-tested decisions and fewer blind spots.
