The Worst-Case Risk Test converts anxiety into a concrete downside plan. First state the decision, then enumerate credible worst-case outcomes rather than treating risk as one undifferentiated feeling. For every scenario, ask whether you could remain safe, functional, and reasonably content if it happened. If the answer is yes, explicitly accept that price and reserve the resources needed to recover. If the answer is no, design safeguards that prevent or materially reduce the outcome before proceeding. The relevant downside must reflect current circumstances: an early-career founder may focus on rent and a flight home, while an established founder may face reputation, relationship, or quality risks. The result is a decision based on bounded consequences and recovery options rather than emotional avoidance.
Origin
Jasmine Star read Sam Parr's 2017 Anti-MBA post describing his risk process, and Parr confirmed that he still used it while evaluating Hampton. Extracted from The Jasmine Star Show.
Core principles
- 01Define risk instead of reacting to vague fear
- 02Separate possible outcomes from emotionally imagined danger
- 03Accept survivable downside explicitly
- 04Create safeguards for outcomes you cannot accept
- 05Reassess the relevant type of risk as your circumstances change
How to run it
- 1
State the decision
Write the exact action you are considering and the commitment it requires. Avoid broad questions that conceal several different choices.
Pro tip Frame the decision so that a specific yes or no is possible.
Watch out A vague decision produces vague risks.
- 2
List plausible worst cases
Describe the concrete financial, professional, relational, and reputational outcomes that could follow. Distinguish credible downside from catastrophic imagination.
Pro tip Include different categories of risk rather than focusing only on money.
Watch out Do not exclude an uncomfortable outcome merely because it is emotionally difficult to examine.
- 3
Test acceptability
For each scenario, ask whether you could remain safe and build a satisfactory life if it occurred. State honestly whether you accept that outcome.
Pro tip Describe what daily life would actually look like after the setback.
Watch out Do not call an outcome acceptable if it would violate a hard responsibility or boundary.
- 4
Engineer safeguards
For every unacceptable scenario, create preventive controls, limits, reserves, or exit options. The aim is to make the worst case impossible or sufficiently unlikely.
Pro tip Use simple safeguards such as a cash reserve, quality threshold, capped investment, or return plan.
Watch out A safeguard that depends on optimistic future revenue is not a reliable safeguard.
- 5
Commit or decline
Proceed when the remaining downside is acceptable and adequately bounded; otherwise revise or reject the decision. Record the reasoning so emotion cannot silently rewrite it later.
Pro tip Review the decision when your responsibilities or resources materially change.
Watch out Past willingness to take a risk does not mean the same risk remains appropriate today.
In the wild
When Parr considered moving to San Francisco with little money, he treated returning to his parents' home and taking a restaurant job as an acceptable worst case. He reserved $1,000 for a flight and an initial month of expenses while finding work.
→ The downside became concrete, survivable, and funded rather than an undefined reason not to move.
After becoming financially secure, Parr's primary downside was no longer paying rent. He focused instead on avoiding a poor launch and delivering exceptional value so that turning friends into customers would not damage those relationships.
→ The same test adapted from financial survival risk to quality, friendship, and reputation risk.
Common mistakes
Treating every risk as financial
As circumstances change, the binding downside may become reputation, relationships, time, or quality rather than money.
Letting fear remain abstract
Undefined anxiety feels unlimited; naming the scenario exposes whether it is truly intolerable or merely inconvenient.
Accepting risk without a recovery reserve
A survivable scenario still requires the money, time, or support needed to execute the recovery plan.
Is it for you?
Best for
It is best for people considering a consequential but reversible move such as leaving a job, relocating, or starting a business.
Not ideal for
It is not sufficient by itself for irreversible, safety-critical, legal, or highly complex financial decisions requiring specialist analysis.

“One, write out the risk you're deciding on. Two, make a list of possible worst case scenarios. Three, address each possible worst case scenario and…”
“That's true. But it's the process that matters.”
“But I still follow that same framework that I wrote about.”
