Outcomes and judgments depend on the frame from which they're observed. Relativity in physics — Einstein's special and general relativity — says that measurements of time, length, and simultaneity depend on the observer's state of motion and the local gravitational field. There is no single "true" frame; different frames give different but internally consistent descriptions. The same idea applies to strategy and perception. What looks like a win from inside the company can look like a loss to a customer. What looks like a premium product in one market looks like a commodity in another. The "facts" don't change, but their meaning and implications do.
Einstein's insight was that the laws of physics are the same in all inertial frames, but measured values (time, distance) vary. The speed of light is constant; time and space flex. In decision-making, the analogue is that the same situation can be interpreted differently depending on who you are, what you want, and what you already believe. Frame of reference shapes what you notice, what you value, and what you predict. Two observers with different frames can both be "right" about their experience while disagreeing on interpretation.
The strategic use: always ask "relative to what?" and "from whose perspective?" When someone says "we're winning" or "this is expensive," ask: in what frame? Compared to what baseline? Relativity doesn't mean there's no truth — it means truth is frame-dependent. Change the frame (customer, competitor, regulator) and the picture can flip. The mistake is assuming your frame is the only one or the neutral one.
Section 2
How to See It
Relativity shows up whenever the same situation is described differently by different parties: "We're the premium choice" vs "They're overpriced." "We're moving fast" vs "They're reckless." Look for disputes that resolve once you specify the frame (customer segment, time horizon, metric). When people talk past each other, they're often in different frames.
Business
You're seeing Relativity when pricing is "high" or "low" only relative to alternatives and willingness to pay. A $50/month tool is expensive for a solo dev and cheap for an enterprise. The number is the same; the frame (customer, use case) determines the judgment. Positioning and messaging are attempts to set the frame — "compared to X we're better."
Technology
You're seeing Relativity when performance is evaluated. "Fast" depends on the baseline: fast for a legacy migration, slow for a greenfield app. Latency is relative to user expectation and to what competitors deliver. Benchmarks are frame-setting; the choice of benchmark is a choice of frame.
Investing
You're seeing Relativity when valuation is "rich" or "cheap." Multiple and comps are frame-dependent: growth vs value, sector vs cross-sector. The same company can look expensive in one frame and cheap in another. Time horizon (hold for 1 year vs 10) is another frame that changes the conclusion.
Markets
You're seeing Relativity when "market share" or "leader" is claimed. Leader by what measure? Revenue, users, growth, geography, segment? The frame defines the answer. Competitors will choose frames where they lead; you choose frames where you do. Neither is absolute.
Section 3
How to Use It
Decision filter
"When evaluating a claim or a metric, ask: relative to what? From whose perspective? In what time frame? Make the frame explicit. If the conclusion changes when you change the frame, you're in a relative situation — design your strategy and communication for the frames that matter."
As a founder
Set the frame in your favour where you can. Position relative to the comparison that helps you (e.g. "faster than X," "cheaper than Y for this use case"). When receiving feedback or criticism, identify the frame — customer segment, competitor view, investor lens — and decide whether that frame matters for your goals. The mistake is believing there is one objective "truth" about your product or company. The second mistake is ignoring frames that matter to customers or capital and losing them.
As an investor
Explicitly choose the frame for valuation and thesis. Growth vs value, short vs long horizon, bull vs bear case — each is a frame. Stress-test the investment by changing frames: how does it look in a recession? In a different rate regime? From a customer's perspective? Relativity reminds you that "cheap" or "great" is always relative.
As a decision-maker
When people disagree, surface the frame. Often the disagreement is not about facts but about which comparison or which stakeholder view counts. Name the frames, then decide which should drive the decision. Relativity reduces false conflict and clarifies what's actually at stake.
Common misapplication: Using relativity to say "everything is subjective." Relativity means frame-dependent, not arbitrary. Within a chosen frame, you can still be right or wrong. The discipline is choosing the right frame for the question, not abandoning objectivity.
Second misapplication: Ignoring frames that matter to others. Your frame may be "we're building for the long term." The customer's frame may be "does this work today?" The investor's frame may be "what's the exit?" If you only operate in your frame, you'll be surprised when others don't share your view. Map the key frames and address them.
Einstein established that time, space, and simultaneity are relative to the observer's state of motion. The mental habit — question the "obvious" frame, look for invariants, and relate different perspectives through consistent rules — applies beyond physics to any situation where perspective shapes judgment.
Nadella shifted Microsoft's frame from "us vs competitors" to "us with customers and partners" and from "know-it-all" to "learn-it-all." The reframe changed how the company evaluated success and made decisions. Relativity in practice: change the frame, change the strategy and culture.

Visual Explanation
Relativity — Same situation, different frames. Outcome and judgment depend on who is observing and from what position.
Section 7
Connected Models
Relativity ties to how we set and shift perspective. These models either define frames or help correct for them.
Reinforces
Frame of Reference
Frame of reference is the explicit model: the coordinate system and assumptions from which you observe. Relativity is the principle that conclusions depend on it. Making the frame explicit is the first step to using relativity well.
Reinforces
Observer Effect
The observer changes what is observed. Relativity adds that the observer's frame (position, motion, goals) also changes how the observation is interpreted. Both warn against assuming a "view from nowhere."
Reinforces
Map vs Territory
The map is a representation that depends on purpose and frame. Relativity says the same territory can yield different maps for different observers or uses. Updating the map when the frame changes is critical.

Miles's Law
"Where you stand depends on where you sit." Miles's Law is relativity applied to organisations: your position (role, incentives) shapes your view. Understanding others' "where they sit" explains their stance.

One Key Quote
"It is the theory which decides what we can observe."
— Albert Einstein
Einstein meant that the conceptual frame (theory) shapes what counts as an observation and how it's interpreted. In strategy, the "theory" is your frame — customer, competitor, investor. Change the theory (frame), and what you see and what you do change with it.
Section 9
Analyst's Take
Faster Than Normal — Editorial View
Always specify "relative to what?" When someone says we're winning, losing, cheap, or expensive, ask for the comparison. The frame is usually implicit. Making it explicit reveals whether the claim holds in the frames that matter.
Set the frame when you can. Positioning and narrative are frame-setting. You want customers and investors to use the frame where you win (e.g. "best for X," "compared to legacy we're Y"). Competitors will set frames where they win. The battle is often over whose frame gets used.
Stress-test by changing frame. How does the strategy look from the customer's perspective? The competitor's? The regulator's? If it only looks good in your frame, you're vulnerable. Relativity is a check against frame-blindness.
Invariants still exist. Some things don't depend on frame: cash flow, churn rate, ship dates (if measured the same way). Use invariants for shared truth; use frame-awareness for interpretation and persuasion.
Miles's Law in meetings. When people disagree, ask where they sit — role, incentives, information. Often the disagreement is frame-based. Naming the frames doesn't always resolve it, but it makes the disagreement tractable.

Test Yourself
Is this mental model at work here?
Scenario 1
A product is described as 'expensive' by some users and 'great value' by others. The price is the same.
Scenario 2
Two departments disagree on whether a project succeeded. One cites revenue impact; the other cites strategic positioning.
Scenario 3
A company claims to be 'the market leader.' A competitor claims the same. They use different definitions of market and leader.
Scenario 4
An investor says a stock is cheap. Another says it's expensive. Both use the same P/E ratio.

Summary: Relativity is the dependence of observation and judgment on frame of reference. Specify "relative to what?" Set the frame when you can; stress-test by changing it. Invariants exist, but interpretation is often frame-dependent.
Marketing as frame-setting: how to position a product in the customer's frame so they see you as you want.
Context is the set of circumstances that define the frame — who, when, where, what goal. Relativity says context isn't optional; it's what makes the interpretation. Missing context is missing the frame.
Tension
Confirmation Bias
Confirmation bias is sticking to one frame (the one that confirms prior belief). Relativity says multiple frames exist; the bias is refusing to switch or to make the frame explicit. Good judgment requires testing conclusions across frames.
