Background
The concept of "Invert, Always Invert" has its roots in ancient philosophical traditions, particularly within Stoicism. Philosophers like Seneca and Epictetus advocated for considering worst-case scenarios to build resilience, a practice known as premeditatio malorum or "premeditation of evils".
However, the modern formalization of this approach is often attributed to the German mathematician Carl Gustav Jacobi, who famously advised, "Invert, always invert" when faced with complex problems. Jacobi's method involved reversing problems to gain new insights, a strategy that has since been adopted in various fields including engineering, business, and decision-making.
This principle was popularized in modern times by Charlie Munger, the renowned investor and vice-chairman of Berkshire Hathaway. Munger emphasized that by looking at problems backward—thinking about what to avoid, what could go wrong, or the undesirable outcomes—one could uncover solutions that might otherwise remain hidden.

Netflix: A Story of Inversion in Action
In the early 2000s, Netflix operated as a DVD rental-by-mail service, a novel idea that was gaining traction. Customers could browse online, order DVDs, and receive them in the mail. But beneath the convenience lay a significant pain point: late fees. Similar to traditional video rental stores, Netflix charged customers penalties for failing to return DVDs on time. Late fees, while a reliable revenue stream, became a source of frustration for customers, tarnishing their experience and loyalty.
As customer complaints about late fees mounted, Netflix’s leadership faced a critical decision. Late fees were ingrained in the business model, providing a financial incentive for users to return DVDs promptly. Yet, they also created negative sentiment that risked damaging the company’s reputation and growth. To address this, Netflix applied the principle of inversion.
After months of struggling with the question, “How can we better manage or justify late fees?” they reframed the problem:
“What if we eliminated late fees entirely?”
This radical inversion shifted the focus from improving an imperfect system to removing the root cause of dissatisfaction altogether. It was a bold idea, as late fees were not just a source of revenue but a fundamental aspect of the DVD rental business model.
The inversion forced Netflix to rethink how it operated. Without late fees, they needed a new way to encourage customers to return DVDs.
This line of thinking led to the creation of the subscription model.
Customers would pay a flat monthly fee for unlimited DVD rentals, with the freedom to keep DVDs as long as they wanted. The removal of late fees made the service far more appealing and customer-centric.
The results were transformative. Customers embraced the subscription model enthusiastically, appreciating the simplicity and predictability of the pricing. By eliminating the frustration of late fees, Netflix significantly improved customer retention and loyalty. Meanwhile, competitors like Blockbuster, which relied heavily on late fees for revenue, struggled to adapt to the changing market dynamics.
This strategic use of inversion did more than solve a short-term issue. It set Netflix on a new trajectory, allowing the company to evolve into a dominant force in the home entertainment industry. The subscription model became a blueprint for its later ventures, including the groundbreaking transition into streaming.
By asking, “What should we stop doing?” rather than, “What should we improve?” Netflix not only solved a critical problem but also pioneered a customer-first business model that propelled it to industry leadership. The decision to invert their thinking remains one of the most pivotal moments in Netflix’s history.
How You Can Apply This Mental Model to Your Products?
The principle of inversion can be applied to multiple facets of product management - below are some key areas where inversion is particularly impactful:
1. Problem Identification
Traditional Approach: What features will delight our users?
Inverted Approach: What frustrates our users the most, and how can we eliminate it?
Inversion helps product managers focus on reducing friction and addressing pain points, which often simplifies the product and leads to greater customer satisfaction than adding new features. For example, instead of asking what makes a payment process better, invert the question: “What makes it frustrating?”, to bring out critical issues like unclear error messages or cumbersome forms etc.
2. Risk Management
Traditional Approach: What should we do to minimize risk?
Inverted Approach: What are the top 3 worst failures that could happen?
Risk is a multifaceted concept that can be difficult for the human mind to fully grasp. Traditional approaches to risk minimization often focus on areas we are already aware of, leading to a natural bias toward managing risks within that familiar spectrum. However, this narrow focus can leave significant vulnerabilities unaddressed, especially in areas outside our immediate oversight. By inverting the question, you broaden your perspective, compelling yourself to identify and address the most critical failure points, even those that might otherwise be overlooked.
3. Roadmap Planning and Prioritization
Traditional Approach: What should we build next?
Inverted Approach: What’s unnecessary or outdated, and what should we stop doing?
The traditional approach often assumes that adding more features is inherently better for the customer. However, this isn’t always the case—especially for mature products, where excessive features can overwhelm users and degrade the overall experience. The most successful products are highly focused, excelling at one thing better than any competitor. By asking, “What’s no longer serving our users?” you can streamline the product, simplify prioritization, and potentially unlock billions of dollars in customer value through a more intuitive and impactful user experience.
4. Customer Feedback Analysis
Traditional Approach: What new features are customers requesting?
Inverted Approach: What complaints or frustrations do customers repeatedly mention?
When gathering customer feedback, you’ll often hear comments like, “I wish XXX was possible...” However, as a product manager, your role isn’t to simply turn these wishlists into features. Instead, your job is to uncover the deeper frustrations or unmet needs driving these requests. To do this effectively, invert the question and ask, “What frustrations do customers repeatedly mention?” By focusing on recurring pain points and eliminating them, you address the core issues that matter most, building trust and fostering loyalty with your users.
5. Team Collaboration and Communication
Traditional Approach: How can we work better as a team?
Inverted Approach: What causes misalignment or friction within the team, and how can we remove it?
A team is made up of individuals, each bringing unique characteristics that shape how the team functions. Consequently, the issues that prevent a team from operating effectively are often rooted in people dynamics. In my experience, traditional approaches to identifying these issues tend to yield feel-good answers, as no one wants to single out or criticize a teammate. As a result, the real problems often remain unaddressed. By inverting the question, you create an opportunity for team leaders to surface meaningful insights and pinpoint areas of friction. For example: “Our meetings always run longer than expected,” or “We lack an effective process for agreeing on resource allocation.” This approach fosters honest discussions and actionable solutions.
6. Strategic Decision-Making
Traditional Approach: What opportunities should we pursue?
Inverted Approach: What opportunities should we avoid?
Companies that successfully scale do so by maintaining focus and avoiding distractions. In today’s fast-paced technological landscape, it’s easy to be tempted by the next shiny object and lose sight of core priorities. Inverting the question can be a powerful tool for strategic decision-making, as it helps clearly define the areas the business will intentionally avoid. This clarity enables more meaningful discussions about innovation within the company’s scope. By asking, “What’s not aligned with the company’s vision?” product managers can prioritize initiatives that deliver the highest impact and stay focused on driving meaningful growth.
Conclusion
The principle of "Invert, Always Invert" is a powerful tool for product management and business professionals. By focusing on what could go wrong and how to avoid failure, you can develop more robust and resilient strategies.
Inversion is not just a tool for solving immediate problems; it’s a mindset that encourages curiosity, rigor, and critical thinking. This approach enhances problem-solving effectiveness, improves decision-making, and builds a culture of continuous improvement.
As Charlie Munger aptly put it:
"It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid, instead of trying to be very intelligent."
