Everything in Life Has an Opportunity Cost

“Opportunity cost is a huge filter in life. If you’ve got two suitors who are really eager to have you and one is way the hell better than the other, you do not have to spend much time with the other. And that’s the way we filter out buying opportunities.”
Charlie Munger, Investor

Everything in Life Has an Opportunity Cost

Doing One Thing Makes You Sacrifice the Opportunity to Do Something Else of Value

In economics, opportunity cost is the cost of not choosing the next best alternative for your money, time, or some other resource.

One of the foundational principles in economics is affirmed by the popular American aphorism, “There ain’t no such thing as a free lunch.” Resources are scarce. When resources (time, money, mindshare, autonomy, and all that) are scarce, selecting one opportunity necessitates forgoing other opportunities.

Life is all about values and priorities. You face trade-offs. Life requires of you to make choices among mutually exclusive alternatives. Every time you select something, you forfeit other alternatives and the concomitant benefits. The cost of something is what you will give up to get it. This is opportunity cost.

You Can Do Anything but Not Everything … What Will You Sacrifice When You Choose One Option Over the Others?

When mulling over multiple choices, the quality of any option cannot be assessed in isolation from its alternatives. The price you pay (or the sacrifice you make, or the benefits you give up) for doing what you’ve chosen to do instead of doing something else is the opportunity cost.

In sum, an opportunity cost is the cost of passing up the opportunities that a different option would have afforded.

Many costs are calculated in terms of money. However, just because you don’t have to spend money to do something does not imply that the options you face are without their costs. For example, you don’t have to spend money to go for a hike or watch a sunset, but there is an opportunity cost there too. You could have used that time to do something else you value—visiting a friend or reading a book, perhaps.

  • If you decide to invest two years and some $100,000 getting an MBA at a brand-name business school, there’s an opportunity cost; it costs you lost wages and all the things you could have pursued during that time and with that money. But you anticipate that getting your MBA will pay off by way of a better job in a better company with a better salary.
  • If you spend your weeklong vacation taking your parents to a beach destination in Florida, there’s the opportunity cost of not going to Paris with your spouse.
  • Opportunity Costs Apply to All Your Choices If you decide to wake up twenty minutes earlier in the mornings to leave home sooner to work and beat the horrendous traffic, there’s the opportunity cost of twenty minutes of extra snoozing.
  • When the refrigerator at home breaks down and needs replacement, you will have to give up buying that latest big-screen TV you’ve been coveting.
  • There’s an opportunity cost to even reading this article at this moment. You could have been watching TV, taking a nap, calling up a friend, or moving on to another article in the time you’re devoting to reading this article.

In a nutshell, even decisions that appear to be no-brainers carry the hidden costs of the options you will decline. Thinking about opportunity costs may not change the decision you make, but it will give you a more rational assessment of the full implications of your decision.

Opportunity Costs Apply to All Your Choices—Big and Small

Opportunity cost is a concept of great magnitude. It is one of those apparently simple concepts in social sciences that are difficult to master and tough to put into consistent practice. Tim Harford, the British author of The Undercover Economist offers a particularly instructive example of appreciating opportunity costs in his Financial Times column:

Consider the following puzzle, a variant of which was set by Paul J Ferraro and Laura O Taylor to economists at a major academic conference back in 2005. Imagine that you have a free ticket (which you cannot resell) to see Radiohead performing. But, by a staggering coincidence, you could also go to see Lady Gaga—there are tickets on sale for £40. You’d be willing to pay £50 to see Lady Gaga on any given night, and her concert is the best alternative to seeing Radiohead. Assume there are no other costs of seeing either gig. What is the opportunity cost of seeing Radiohead? (a) £0, (b) £10, (c) £40 or (d) £50.

Answer: Going to see Lady Gaga would cost £40 but you’re willing to pay £50 any time to see her; therefore the net benefit of seeing Gaga is £10. If you use your free Radiohead ticket instead, you’re giving up that benefit, so the opportunity cost of seeing Radiohead is £10.

Learn to Evaluate Life Choices Via the Lens of Opportunity Costs—The Stakes Become Clearer

Evaluate Life Choices Via the Lens of Opportunity Costs You live in a world of scarcity and must therefore make choices. You cannot avoid regret since there are opportunity costs for every choice you will make.

Everything in life is about opportunity costs. Every time you say “yes” to a choice, you are also saying “no” to everything else you may have accomplished with your time, money, and resources.

Opportunity cost is a commanding tool that you should be wise to apply to all decision-making. If you integrate this concept into your thought process, you will not only make judicious choices, but also better understand the world in which you live.

Idea for Impact: Whether you’re choosing graduate school, mulling over switching careers, starting a business, investing your money, buying a car, or frittering away your evening watching TV, considering the value of forgone alternatives will help you make better choices. Make the lens of opportunity costs the underpinning of your decision-making processes.

Let Go of Sunk Costs

When people put their weight behind an idea or a belief, they become invested in it. They are likely to fight its corner rather than discard that idea or renounce their prior decision.

This tendency to throw good resources after bad, rather than cut losses, is the Sunk Cost Fallacy.

Quitting is Not Always Wrong

'Thinking, Fast and Slow' by Daniel Kahneman (ISBN 0374275637) People frequently become stuck with poor decisions that they keep holding on to in hopes that they will eventually prove their efforts worthwhile. Here’s Nobel laureate in economics Daniel Kahneman (author of Thinking, Fast and Slow, the bestselling exposition of human irrationality) in an interview with financial journalist Morgan Housel:

When I work I have no sunk costs. I like changing my mind. Some people really don’t like it but for me changing my mind is a thrill. It’s an indication that I’m learning something. So I have no sunk costs in the sense that I can walk away from an idea that I’ve worked on for a year if I can see a better idea. It’s a good attitude for a researcher. The main trap that young researchers fall into is sunk costs. They get to work on a project that doesn’t work and that is not promising but they keep at it. I think too much persistence can be bad for you in the intellectual world.

Don’t Become Biased Against Quitting

Sunk cost fallacy, also called the Concorde Effect Sunk cost fallacy is why people who have already wasted money on tickets to an awful movie continue to watch it to the end and waste their time instead of walking out of the cinema hall. It’s the urge to justify previous decisions using the next one—for example, when people force themselves to munch their way through an unsavory meal at a restaurant or when people waste time in dead-end romantic relationships because they’ve already devoted so much time to the relationships and irrationally hope things will improve someway.

Some leaders continue a project once an initial investment is made and found flawed because stopping the project would be tantamount to conceding that previously-allocated resources have been wasted. For this reason, the sunk cost fallacy is also called the ‘Concorde Effect’ after the Anglo-French supersonic jet. In the ’60s, even though there was never a sufficient demand from airlines for the Concorde, the British and French governments continued to subsidize the development and production of the Concorde instead of admitting that they had wasted billions on a non-viable undertaking. The airline industry had long understood that the economics of supersonic transport were dubious, which had forced Americans to abandon their preliminary studies of supersonic jets.

Idea for Impact: Let to Cut Your Losses When Something’s Not Working

Sunk cost fallacy - Know How to Cut Your Losses When Something's Not Working Sunk costs are backward-looking decisions. Don’t become excessively focused on a specific goal or outcome—you’ll become inflexible and unyielding. You’ll narrow your options and make yourself feel more limited and inhibited.

Don’t get attached to ideas and become affected by the sunk cost fallacy as your projects develop. Remain objective, identify the warning signs of losing propositions, and abandon lost causes where sensible. As the American cartoonist Charles Schulz of Peanuts fame once said, “No problem is so formidable that you cannot walk away from it.”

Everything Takes Longer Than Anticipated: Hofstadter’s Law [Mental Models]

Think of your weekend days. You typically wake up and think of all the free time at hand. You plan a day of leisure. You intend to run some errands and get a few things done around the house. Yet, at the end of the day, you’ve done barely half of what you originally set out to do.

People Habitually Underestimate the Time Tasks Take

Almost everything that humankind has ever wished for—from renewing a driver’s license to achieving peace between countries at war—seems to have not completed within the time originally planned.

As the following case studies will illustrate, interruptions, deferrals, and delays characteristically result in cost overruns, benefit shortfalls, and disputes.

  • Sydney’s Opera House was originally forecast in 1957 to be completed in 1963. The magnificent performing arts complex formally opened only in 1973 and cost 15 times the original budget.
  • Hofstadter's Law: Boeing 787 Dreamliner Delays and LossesWhen Boeing first launched its 787 Dreamliner aircraft in 2004, it ambitiously planned for first flight in September 2007. After six delays in the design and prototype phases, the 787 first flew only in December 2009. First aircraft delivery was scheduled for 2008, but didn’t happen until September 2011, more than three years behind schedule. Then, after a series of early in-service technical and operational problems, Boeing embarked on serious drawn-out repairs on 787s. Following yet more production delays, the 787 started flying full-fledged only in 2013. The innumerable delays and cost overruns associated with the 787 program became a financial nightmare for Boeing’s investors. Boeing took nine years to get the Dreamliner off the drawing board and into mature service at a total development cost of $32 billion—twice as long as the company’s original estimation and more than five times more expensive.
  • Less than 50 days before the start of last year’s Summer Olympic Games in Brazil, the state of Rio de Janeiro declared a “state of public calamity” citing severe delays and acute cost overruns. The New York Times reported, “The city is a huge construction site. Bricks and pipes are piled everywhere; a few workers lazily push wheelbarrows as if the Games were scheduled for 2017.”

Hofstadter’s Law: We Chronically Underestimate the Time Things Take

Hofstadter's Law: We Chronically Underestimate the Time Things TakeThe American cognitive scientist Douglas Hofstadter conceived an ironic and recursive rule to characterize the observation that everything takes longer than planned.

Hofstadter’s Law states, “It always takes longer than you expect, even when you take into account Hofstadter’s law”

Hofstadter first discussed this law in his Pulitzer Prize-winning Gödel, Escher, Bach: An Eternal Golden Braid, a book popular among American computer programmers.

Underestimating Task-Time Means Constantly Rushing to Finish Things

According to planning fallacy, when people predict the time it takes to complete a task, they make their estimations by considering the various steps they have to take, but fail to imagine the pessimistic conditions where things could go wrong.

Project Delays: Hofstadter's Law, Planning Fallacy and Optimism BiasIn other words, thanks to optimism bias, people are generally too optimistic about the time it takes for them to complete a task, even when they are explicitly asked to think about potential obstacles.

Hofstadter’s Law also alludes to,

  • Superiority Bias where people overrate their own positive qualities and abilities—and underrate their negative qualities—when compared with others. “This takes three hours for the average Joe, but I am smarter, and I can do it in two hours.”
  • Beneffectance Bias where people perceive themselves as selectively accountable for the desired—but not the undesired—outcomes. “Last week, this took me 45 minutes, but the delay was because of conditions beyond my control. Today, I have full control; so I should take just 20 minutes.”

Idea for Impact: The problem with unforeseen delays is that you can’t foresee them, no matter how comprehensively you plan

Though somewhat silly in its recursive character, Hofstadter’s Law observes that, irrespective of how carefully you plan, every project will be prone to something unanticipated that will hinder its timely completion. The law’s recursiveness affirms that, even if you know a project may overrun and build that expectation into your planning, the project will overrun even your new estimated finish time.

Zeigarnik Effect: How Incomplete Tasks Trigger Stress [Mental Models]

Zeigarnik Effect: How Incomplete Tasks Trigger Stress {Mental Models}

People Remember Incomplete Tasks Better than Completed Tasks

When you listen to a song that’s unexpectedly cut off in the middle, your mind will repeatedly inject your thought stream with bits of the song in an attempt to remind you that you’re not yet “done” listening. But, once you listen to that song completely, your mind moves on.

Psychologists identify this tendency for interrupted tasks—and thoughts—to be evoked better than completed tasks the Zeigarnik Effect.

Ruminating about Unfinished Tasks Causes Anxiety

Lithuanian psychologist Bluma Wulfovna Zeigarnik who reported Zeigarnik Effect when working with research advisor Kurt Lewin at the University of BerlinThis phenomenon was first reported in the 1920s by the Lithuanian psychologist Bluma Zeigarnik. Working with her research advisor Kurt Lewin at the University of Berlin, Zeigarnik observed that restaurant waiters seemed to remember a complex order just so long as the order was in the process of being prepared and served, but not after it was finished.

Zeigarnik Effect and Cliffhangers

Zeigarnik effect is in force when an episode of a TV series ends with a cliffhanger leaving the audience in suspense until the next episode. Teachers who conclude their lectures by posing a perplexing question stimulate the class to think about the answer until the next class.

In another prominent use of the cliffhanger and the Zeigarnik Effect as a literary device, the English novelist Charles Dickens released most of his novels in the form of serial publications, i.e. in monthly or weekly installments. Dickens’s cliffhangers initiated such anticipation in reader’s minds that his American fans would gather at New York City’s docks for the latest installment to arrive by ship from England. The installment format also allowed Dickens to rework his character development and his plots depending on audiences’ reactions.

Zeigarnik Effect and Cliffhangers

Zeigarnik Effect and the Need for Closure: Task Management

Psychologist Bluma Zeigarnik’s research showed that the human mind hates unfinished tasks. Zeigarnik theorized that incomplete tasks incite “psychic tension” in you, which can be a persuasive impetus to complete the task. As long as you leave the task unfinished, your brain is in an uncomfortable position. Thoughts of the task serve to remind your brain of what it needs to do to get “comfortable” once again. As soon as you complete the task, this tension is alleviated, and in so doing, your brain lets the mind to release thoughts of the task from consciousness.

In other words, much mental effort is required when your tasks are interrupted or are still in the process of being completed.

From a time-management perspective, uncompleted tasks and unmet goals have a propensity for popping into your mind and worrying you persistently until the task is completed and the goal reached.

Emptying Your Mind of Nagging Tasks to Get Things Done

'Willpower: Rediscovering the Greatest Human Strength' by Roy F. Baumeister and John Tierney (ISBN 0143122231) According to John Tierney and Roy Baumeister’s Willpower: Rediscovering the Greatest Human Strength, further research in cognitive psychology has suggested that the Zeigarnik effect exists not just until you actually finish a task but also until you make concrete plans related to the task.

… turns out that the Zeigarnik effect is not, as was assumed for decades, a reminder that continues unabated until the task gets done. The persistence of distracting thoughts is not an indication that the unconscious is working to finish the task. Nor is it the unconscious nagging the conscious mind to finish the task right away. Instead, the unconscious is asking the conscious mind to make a plan. The unconscious mind apparently can’t do this on its own, so it nags the conscious mind to make a plan with specifics like time, place, and opportunity. Once the plan is formed, the unconscious can stop nagging the conscious mind with reminders.

According to Willpower, one research study asked students to think about an important exam. Half of the students were asked to put in writing specific plans of what/where/when they would study. Later, all students were asked to do a word association test. The group of students that did not write any study plans produced more word associations related to studying because studying was still on their mind; the group who did write down their study plans did not exhibit a comparable bias during the word association test.

Emptying Your Mind of Nagging Tasks to Get Things Done

The Zeigarnik Effect is the central theorem in David Allen’s legendary “Getting Things Done” method for task-management works.

Allen reasons that the dominant cause of everyday anxiety is that you are never truly sure of all the ‘things’ you’re supposed to do. You know you’ve got things to take care of and haven’t. Therefore, your mind keeps incoherently revisiting all that’s important but not yet completed. These “open loops” occupy much of your cognitive effort and debilitate your attention, causing anxiety, sapping your energy, and draining your willpower.

The primary benefit of using Allen’s Getting Things Done system is to reduce anxiety by emptying your mind of nagging tasks, filing away (or writing down) everything that must be done, placing them into a processing system, and scheduling chunks of time to single-mindedly do important things.

Human Mind Hates Unfinished Tasks

'Getting Things Done' by David Allen (ISBN 0670899240) According to the Zeigarnik Effect, unresolved and interrupted tasks thieve the attention of your brain until you have a clear—if subconscious—proposal of what you’re going to deal with them.

Just the simple act of capturing a task that reaches your head can achieve that sense of completion. Even if you haven’t completed the task, you’ll know that you’ve accomplished what could be done up to the moment.

Here’s three clever ways to use the Zeigarnik Effect to your advantage:

  • Use the Two-minute ‘Do-It-Now’ Rule. See my previous article on this task management discipline—in a nutshell: act immediately upon a contemplated task if it can be completed in less than two minutes. Don’t add it to your to-do list.
  • Make a Concrete Plan. Whenever you have a task in mind, stop doing whatever you’re doing, take a blank sheet of paper, and invest one minute to plan and record how you intend to tackle the task. If you intend to write an essay, write an outline; if it’s a report, start the list of contents.
  • Use To-Do Lists Judiciously. Establish and peruse a trusted system to capture your projects and tasks, and the commitments you have to yourself and others. According to David Allen’s Getting Things Done, your human brain is an ineffective and unreliable repository of all the things you try to cram into it. All this “stuff” collectively clutters your headspace. Getting all your stuff out of your head and into a trusted system can bring about a profound sense of relief.
