Top 50 Mental Models

A curated collection of the best problem solving frameworks in product management and design.

A curated collection of the best problem solving frameworks in product management and design.

Each model provides a lens to enhance your structured thinking, communication, and decision-making when solving complex problems. These mental models serve as cognitive tools that simplify complexity, reveal hidden patterns, and illuminate paths forward in product development. From understanding user behavior to making strategic trade-offs, these frameworks offer practical wisdom for navigating the multifaceted challenges of creating products people love.

1.

Jevons Paradox

The observation that increased efficiency in resource use tends to increase (rather than decrease) total consumption of that resource. First noted with coal: more efficient steam engines led to more coal consumption as new uses became economical. In AI today, efficiency gains will paradoxically increase total energy consumption through expanded deployment and novel applications.

William Stanley Jevons (economist who identified the pattern in coal use in 1865)

The recognition that emptiness or absence is a critical design element, not merely the lack of something. In architecture, empty space creates function (rooms); in music, silence frames notes; in graphic design, white space creates focus.

Lao Tzu (ancient Chinese philosopher); Dieter Rams (modernist designer known for minimalism); John Cage (composer who explored silence)

A framework for managing unsolvable problems – ongoing dilemmas where both poles have value and need balancing rather than choosing one side. Unlike problems with solutions, polarities (quality vs. speed, individual vs. team) require managing both poles simultaneously.

A leadership response framework for volatile, uncertain, complex, and ambiguous (VUCA) environments. For each VUCA challenge, VUCA Prime offers a corresponding leadership approach: Vision counters volatility; Understanding counters uncertainty; Clarity counters complexity; Agility counters ambiguity.

A philosophical paradox where a perfectly rational donkey, placed exactly between two identical hay piles, would starve to death because it has no reason to choose one over the other. This illustrates how too much symmetry in options can lead to decision paralysis.

The observation that "institutions will try to preserve the problem to which they are the solution." Organizations founded to address specific problems often resist truly solving them, as doing so would eliminate their reason for existence.

Shirky Principle

The observation that "institutions will try to preserve the problem to which they are the solution." Organizations founded to address specific problems often resist truly solving them, as doing so would eliminate their reason for existence.

Clay Shirky (technology writer who articulated it in 2010); similar to the economic concept of "regulatory capture"

The principle that non-perishable things (ideas, technologies, books) can be expected to survive in proportion to their current age. If a book has been in print for 100 years, it will likely remain for another 100 years – while a new book will likely disappear quickly.

Each of these mental models offers a lens to dissect problems and make better decisions. By internalizing this diverse toolkit – from cognitive biases like the Zeigarnik Effect to economic principles like Jevons Paradox, from creative heuristics like the Vacation Principle to structured frameworks like Polarity Mapping – we can approach challenges with more clarity, creativity, and rigor. The conceptual metaphors provided for each model (like "Future Rearview Mirror" for the Regret Minimization Framework or "Problem Preservation" for the Shirky Principle) help communicate and remember these powerful ideas, making them not just intellectual tools but also shared narratives for team learning and leadership.


Sources: The explanations and contributors draw on a range of literature spanning psychology, economics, design, and systems thinking. These models have been developed by diverse thinkers like Jeff Bezos, Herbert Simon, Don Norman, and Nassim Taleb, among many others noted in the document. Each model provides a unique way to cut through complexity – whether by simplifying, looking at opposites, considering human biases, or structuring thinking – and collectively they form a robust "latticework" of mental models for better problem-solving and decision-making.
