Charle Munger 's questions list

CHECKLISTS

Helpful for achieving goals, making choices, solving problems,evaluating what is likely to be

true or false etc.

Use notions

- Use the big ideas that underlie reality

- Understand what something really means

- Simplify

- Use rules and filters

- Know what I want to achieve

- Find and evaluate alternatives

- Understand consequences and their consequences on the whole

- Quantify

- Search for and base things on evidence

- Think things through backward

- Remember that big effects come from large combinations of factors

- Evaluate the consequences ifI'm wrong

What is the issue?

- What's the question? What is this really about?

- What's the essence or nub of the issue? What is then the key question?

- Relevant? Solvable? Important? Knowable? Utility - applicability?

- Do I understand what the subject is all about? In order to have an opinion on a subject I need

some relevant data and basic knowledge about the subject, otherwise just say:"I don't know".

- Is my judgment here better than others?

- What must I predict here and is it predictable?

- Is a decision needed? What happens if I don't deal with this? Is this something I can do

anything about? Should "I" do this?

- Over what period of time am I considering this issue? Where am I at present?From whose

point ofview?

- Simplify by deciding big "no-brainer questions" first and beg infrom where I am.

Understand what it means

- Translate words and ideas in terms I understand. Do I understand what words and statements

really mean and imply? Does it mean anything? Will it help me make useful predictions on

what is likely to happen?

- Do I understand how and why something works and happens? What is it doing? Why does

it do that? What is happening? How and why is this happening? What is the consequence of

this (observation, finding, event, experience...)?

- Definitions and implications?

Filters and Rules

- Use filters incl. rules and default rules -what test(s) can I make?

- Adapt to my psychological nature, abilities, advantages, and limitations

- Consider values and preferences and therefore priorities and what I want toavoid

What do I specifically and measurable want to achieve and avoid and when and why?

- What future "value" do I want toachieve? Target numbers? Target effects? Time horizon?

- Assume I have already reached my target. What would this imply in numbers and effects?

What must then have been achieved? Is it (target) reasonable? Is it reasonable if I reverse

this to the present?

- Do I have ways to measure to what degree my goal is being achieved? Key variables or

components of yardstick?

- If I achieve this what will happen? Do I want that to happen?

- Can I break my goal into short-term goals with deadlines?

- What is my real reason for doing this? Is it because I want to or because I have to? Have I

stated my goal from internal and external realities or am I biased now or influenced by some

psychological forces?

- Can I express my goal in a way that makes it easier to see how it is going tobe achieved?

- Is this the true goal for what I want to achieve?

What is the cause of that?

- To achieve my goal I must understand what causes my goal to be achieved

- What is the equation for goal and what evidence do I have for that?

- What don't I want to achieve? What causes non-goal and what can I do to avoid that? What

must I not do or what must I avoid?

- What variables influence the system? What are the critical forces and variables, the ones

that account for the main outcome? What is the key unknown? What is the certainty with

which I can evaluate, optimize ... the different variables?

- Which variables are dependent on other variables (or situation, environment,context,

timing, behavior) and which ones act independently of each other?

- What force causes a variable to be achieved? What produces the force(s)? Are there short

and long-term forces? What is their relative strength? How do they combine and interact

and what are the effects? How can I get many forces to operate together in the same

direction? What lack of force would destroy the system? What produces this force? How

predictable are they? What can the forces in place rationally expect to cause?What forces

are temporary and which ones are permanent? How will the system change as the forces

that act on the variable change?

- How resistant is the system to a change in the variables and/or forces? What are the likely

wanted and unwanted short- and long-term consequences (on numbers and effects)of

changes (up/down) - scale, size or mass, strength, intensity, length, time horizon, environment,

participants etc. - in the variables or forces? What happens when a number of small causes

operate over a long time? What are the consequences if a force acts on the variable over a long

time? Which force could change it? What is needed to create a critical mass? What forces

when added can create a critical mass? How? Will something else happen

when I change a variable or force? What must happen for a force to change? Can a change

produce other consequences (observe that I am interested in effects on thewhole system  and

the final outcome)? Does a change in one variable make a dramatic difference in

outcome? Will the properties also change? What are the consequences if the relation

between the variables changes? What is the change point? Barriers? Catalyst?Tipping

point? Inflection point? Break point? Limits? Is there a time lag before effects happen?

Feedback? What can speed up the cause? What are the critical points when the effects get

reversed? What can I change in the equation and what can others change? How?Who?

When? Which variables must I change to achieve goal? How can I measure the amount of

change? Degree of sensitivity if I change the assumptions? Effects on goal and path? What

will happen if I hold one variable constant? If I at the same time increase one variable and

decrease another? Net effect? If I change one variable or force at a time? What is it in the

environment that can change the situation? What other advantages and disadvantages can

I achieve if I optimize one of the variables? What must happen to cause a change in outcome?

Is it still a variable if I change the conditions?

- Are there exceptions to the equation and why? What conditions are required to achieve

goal? Has my goal different cause short-term and long-term? Is the cause time-dependent?

Can I deduce the cause by observing the effects? Have I looked upon the systemfrom

different angles and viewpoints? What does the measurement of the subject depend on?

- What is the major constraint that limits the goal from being achieved?

What available alternatives do I have to achieve my goal?

- Judge alternatives in terms of goal, subjectin question, rules and filters, cause and effect,

human behavior, evidence, counter evidence, simplicity and opportunity cost ofmoney,

time, other resources, effort, understanding, risk and mental stress.

- What evidence (incl. models) do I have that these alternatives are most likely to achieve

goal?

- Are they depending on time horizon or event?

- What are the likely consequences of each action? What possible outcomes canhappen?

Likelihood? How desirable is each consequence?

- Do I forego any future opportunities if I make a specific action now?

What are the consequences?

- Find out which alternative are most likely to achieve my goal by estimating their likely

consequences

- If I do this, what will happen? Why will this not happen?

- What are the likely (logical) wanted and unwanted (or unintended) consequences

(quantitative and qualitative) and consequences of consequences (immediate and over the

course of a long period) of each alternative!event (proposition) factoring in relevant variables?

- What are the different scenarios and outcomes that can happen? What is likelyto happen

short and long-term based on the evidence?

- What can help me make predictions on consequences or if something is likely to be true

or false?

- What must happen for the goal to be achieved? How likely is it that the necessary events

will happen and happen to me? What does the probabilities favor? What will happen if I

reverse the proposition?

- What are the uncertainties that can significantly influence the outcome? What unintended

consequences are there due to repeating effects, complications... ?Is the net effect positive?

Does the consequences predict anything else? What else does this mean?

- What are the consequences if this is true or false?

- Have I considered the whole system from different viewpoints? Have Iconsidered social,

financial, physical and emotional consequences? What are others likely to do?What are my

experiences of earlier behavior? What happens when others do the same?

Bias

- Is there any reason for bias due to self-interest or psychological influences that may cause

misjudgment?

- Is this a biased statement or a fact? What are factual judgments and what are value

judgments?

- How reliable is he? Is he competent enough to judge? Credentials? What is his purpose with

this? Does he have any motive to lie? How does he know that this is true?

The hypothesis

- Based on what I want to achieve; test statement implied by goal or statement for

consequences.

- For every alternative ask: Is this alternative likely to achieve my goal(true)? For proposition

ask: Is this proposition likely to be true?

- How can I test (testability) if this is true? Can I try to prove it is false before I try to see if

it's true?

- What do I need to know if! shall test this statement? I must first find out the equation for

what causes the statement to be true so I know what is the most important Ineed to know

the future true outcome of and then search for the evidence for and against that this will

be achieved. What is the statement that should be proved?

- What is the simplest hypothesis?

Look for evidence and judge the evidence

- How likely is it that the key cause (for goal,non-goal, and proposition) will be achieved?

- When evaluating statements or true/false, look for meaning, motives, causes,consequences

and evidence for and against.

- If this were true what would the consequences then imply? Are the consequences of it not

being true illogical or unbelievable? Does it have any predictability?

- How and where can I find the representative evidence if this is true?What is given? What

are unquestionable truths? Will the test or other ways of measure give the same results when

repeated (reliable)? Can I test for consequences (verifiable)? Is the evidencebased on what

is known and have I interpreted the data correct (valid)? What evidence do Ihave? Evidence

against? What grounds do I have for accepting that evidence? Weight of evidence?What is

the quality of the evidence? How credibleisthe evidence? Dependent on time,

environment? Too small sample? Does the statement agree with the available evidence?

Does it violate any scientific laws or laws of nature?

- What representative information do I have? What is happening by observation?Can I do an

experiment to confirm my guess? Does it agree with experiment?

- What is the track record (case rate, base rate frequency, variability,average rate, degree of

randomness, my own experiences, environment, players, and other relevant factors for the

case) on what happened (worked and not) in the past? Is there any reason to believe that

this record isn't representative for what is likely to happen in the future?What can make

the future a lot different than the past? What's been permanent and what hasn't?

- How long can this continue? What is the major cause(s) now? What force(s) can make it

continue, initiate a change, or stop it and why? Is it likely?

- If I  get evidence that is the opposite of my previous convictions I must ask:How does this

happen? What is going on here? What evidence do I have? What grounds do I have for

accepting the evidence?

Disprove my (or others) conclusion by thinking like a prosecutor

- Consider causes for misjudgments

How can I test and prove that my idea and conclusion is wrong? What reasons arethere

why I might be wrong? Where can I find the evidence that suggest I am wrong? How

credible is my evidence? What facts and evidence disagree with my conclusion/idea?

What major assumptions have I built the case on? Are they built on reality? Are their

consequences logical? Has anyone proved that my assumptions are right? What are the

consequences if my beliefs and assumptions are wrong?

What have I ignored or overlooked? Better alternatives? Have I ignored evidence? Have I taken

into account the limitations when humans are involved? What factors are uncertain and

why? Have I just projected present trends? What have I misinterpreted? Have Iused the right

definitions? Did I consider and combined all the relevant factors? Have I used the

appropriate measure/yardstick? Did I go wrong in the measurement? Have I confused cause

and correlation? What about if my goal is shaped by what I believe is true butit isn't? Are there

random or systematic errors? What other causes can explain my results? Have I considered the

whole system and that interacting parts sometimes canvary in unexpected and unwanted

ways?

- Bias for my own ideas? Is my ego getting in the way ofmaking an intelligent decision? Will

I really beat the historical average/record? Have I looked for contrary effects?

- What do I not see? What is the significance of this? Does an inversion of the assumption

lead to a logical absurdity? Is the opposite more likely? Is there any contrary evidence? What

evidence can prove it is false (or not achieving goal)? What experimental (or experience,

291

observation... ) evidence are there that it's false? More evidence infavor of that? What

causes it to be false?

- Meaning? Can I show that the consequences ofit being true are unbelievable?What is the

implied effect if! trace it out mathematically? Would the opposite of the statement be more

likely? If yes, the proposition is probably false.

What is the downside?

- How can I be hurt? What could possible gowrong? What can turn this into a mistake?

What would the consequences be?

- How often do things go wrong? Surprise factors? What can happen that will dramatically

change the outcome?

- What is the worst thing that could happen - the nightmare scenario? How likely is that?

What will I do if it does? What are the consequences if things go from bad to worse? And

what are then the consequences?

- What are the consequences if I get two or three forces acting in concert against me? Which

alternatives net effects are least worse?

- Execution risk?

- What do I least like? What am I least sure of?

- Can an advantage give me unwanted consequences? How do I lose an advantage?

- How can I structure the "system" to minimize the influence of negatives? Antidotes to what

I don't want happen? Do I have a backup plan for surprises? Can I correct it?What rules

can I install to achieve goal and avoid non-goal? Is there a built-in safety factor?

What are the consequences if I am wrong?

What key thing am I betting on? Do I risk whatis important for me for something of relative low

utility for me?

What is the cost (dollars, time, mental stress etc) of being wrong weighted against the

benefit or value of being right compared to the next best available opportunity?

If I do this because I believe the consequences are in my best interest/it'strue but I turn out

wrong/it is false, what are the short- and long-term consequences (actual loss and

opportunity cost loss) for my goal and can I handle them and/or reverse them?

If I don't do this because I believe the consequences is not in my best interest/it's false but

I turn out wrong/it's true, what are the short- and long-term consequences formy goal and

can I handle them and/or reverse them?

- If I don't take a decision at all now because I don't believe it is necessary but I am wrong,

what are the short-and long-term consequences for my goal and can I handle them and/or

reverse them?

What is the value?

- What is the utility or preference of each ofthese alternatives to me? Which alternative is

most likely to achieve my goal and ultimate objective? Is it really more attractive than the

other choices I have?

- What can I use as criteria to judge my alternatives against each other?

- What do I like best if I weigh the alternatives against each other by assigning their

characteristics numerical values?

- Will it make a difference? Make an impact? How willing am I to accept certain out comes?

What yardstick can be used to measure progress or to measure things against?

- What yardstick(s) do I use? What is the yardstick by which the decision is made?

- How can I easily measure to what degree my goal are being achieved? What indicators can

I track?

- Does the "system" give people an incentive to behave in away sothat my goal will be achieved?

Or does it work against the goal?

How act now?

- Can I execute? What specific action(s) do I have to do (must do) now? What do I need to

do first?

Who is going to do what, where, when, why and how?

Have I decided on where the critical points (time and effects) are?

Have I installed some kind of control stations and rules? Why is this the right rule? What

are the consequences if I don't install this rule (or change my way of doing something)?

What administrative and practical actions must I do due to the rule? How much time will

it take to follow the rule? Can I control how I follow the rule? Can I installa time-limited

rule? Where does the rules not work?

Have I made an active decision?

- AmI prepared to change the decision to reflect new information or new insights on what

works and not?

- Is another decision contingent on a specific event happening? Have Ievaluated the issue as

it exists today? Is the underlying rationale for the decision still there? What new evidence

is there that can change the likelihood? Does my way of measuring progress give any clue

of what is likely to happen in the future? Events - relevant or irrelevant? Does it make any

difference for my goal (independent of time horizon)?

Post mortem or learning from mistakes

- How well did it or didn't it work out? Did I act? Did I do what I said? What did I think at

the time? Original reasons compared to reality?

- Why did I go wrong? How? Where? Opportunity cost?

- How can I figure out if this is going to continue? Have I acted on mymistakes? How act

to not repeat? What should I have done and didn'tdo? What should I concentrate on? What

must I improve? What must I learn?ager

What exactly is the problem

- What do I want to achieve? Why don't I achievemy goal? What happen? How does it

happen? Where does it happen and not? When does it happen and not? Who's affected?

- What causes my goal? What interferes with the factors that cause my goal?Symptoms or

core cause? What is the single most important limiting factor for reaching mygoal? What

principles or assumptions do I base this on? What are the consequences if theyare wrong?

Assuming no limitations, what would be the best course of action? Other consequences?

WHAT ARE THE LIKELY CONSEQUENCES

WHAT ARE THE LIKELY CONSEQUENCES CONSIDERING HUMAN BEHAVIOR?

What is causing me to do this?

What are my present environment and my state of mind? What is rewarding for me to do/say

if I want to avoid pain? What do I perceivetobe the consequences for me? Are they painful

or pleasurable? What psychological tendencies will influence me? Are they likely to cause a

misjudgment?

What is the context?

What does the environment and participants(incl. size) look like? Who is the decision-maker

and what are his criteria for making decisions? Who benefits and who pay? Who is responsible

for outcome? Who and what are influencing the participant's perception ofreality?

Can I judge him?

him? What temptations are there that appeal to his self-interest? What activates his behavior?

What are the consequences?

What are the consequences for me? Will my goal still be achieved? Is what is rewarding for

him also rewarding for me? Is the system set up so that the relevant participant's interest

How shall I behave if! want to guarantee non-goal? Can I now turn around and avoid those?

Is this the right system?

Can I appeal to his self-interest? Can I appeal to fear of losing reputation, money, status,

family..? Can I change his present associations to pain? How can I organize the system to

minimize certain influences? Have I told him what I expect? Have I inspected what is done?

BUSINESS EVALUATION

Filter 1 - Can I understand the business - predictability?

who is going to make the money in this market and why?

- Real Customer-Who decides what to buy and what are hisdecision-criteria?

Filter 2 - Does it look like the business has some kind of sustainable competitive advantage?

- Competitive Advantage- How certain am I that (and can explain why) they are likely to

buy the product or service from the company rather than from someone else? Are the

reasons virtually unchanged from what they were ten years ago? Are these motivations

likely to be unchanged over the next ten years?

product life cycle? Customer cost and incentive to switch supplier? Annual cost differential

against competition? Capital investments needed? Bargaining power? Obsolescence risk?

New customer alternatives? Change in buying habits or power? Competitor potential to

undercut prices assuming same cost structure? What is needed to make sure the advantages

stay sustainable? Growth opportunities left? Is the demand for the productlikely to grow?

would it be and why? If the company would go away for 5 years which competitor would

they bet on and why? How resistant is the business to adversity? Assume the company paid

out all its equity capital, would it still have any value? Could someone with the access to

billions of dollars and talent, successfully compete with the company? How much damage

could a competitor do if he doesn't care about returns? Recession sensitivity?Execution
