In this episode of Hidden Brain, Shankar Vedantam and organizational psychologist Amy Edmondson examine how understanding different types of failures can transform our approach to setbacks. They distinguish between intelligent failures that occur when exploring unknown territory, complex failures that result from multiple small issues aligning, and basic failures caused by inattention or disregarding protocols. The conversation explores how psychological safety in organizations enables honest error reporting and learning, and why context matters when determining appropriate responses to mistakes.
The episode also addresses cognitive biases in personal finance with behavioral economist John Dinsmore. He explains how optimism bias, intertemporal discounting, and expense prediction bias lead people into unsustainable debt, and how marketing tactics exploit consumer psychology. The discussion examines structural economic barriers and why self-compassion matters when facing financial setbacks shaped by forces beyond individual control.

Mistakes happen everywhere, but Shankar Vedantam and Amy Edmondson explain that not all failures are equal—understanding whether a failure is intelligent, complex, or basic transforms how we learn from setbacks.
Intelligent failures occur when venturing into genuinely unknown territory, whether in cutting-edge science or personal life. Edmondson defines these as undesired results from well-prepared experiments designed to be as small as possible. Jennifer Heemstra, a chemist, normalizes failure in her lab, noting that 90% of hypotheses at the research frontier fail—but each failure reveals what doesn't work, bringing researchers closer to answers. Blind dates work similarly: despite preparation, only trying reveals the outcome.
Edmondson emphasizes scaling down intelligent failures to minimize risk. Her mother learned this lesson after a disappointing weekend visit with a potential match, agreeing to just coffee dates afterward. Similarly, pilots train in simulators where failures carry no real-world consequences. The key is reframing setbacks as discoveries rather than deficiencies—Thomas Edison famously said he found thousands of ways that didn't work, turning mistakes into useful information.
Complex failures happen when multiple minor issues unexpectedly align, causing major breakdowns in otherwise safe systems. The 2003 Columbia space shuttle disaster exemplifies this: foam insulation struck the wing during launch, but NASA management dismissed concerns based on past experience with minor foam strikes—a belief that proved fatal when this strike was worse.
Edmondson introduces the "Swiss cheese model," where defensive layers each have holes representing defects. When holes align, small oversights combine into major errors. In one hospital case, understaffing, inexperience, poor lighting, and unclear labels led to a [restricted term] overdose—no single defect caused failure, but together they resulted in harm.
Prevention requires empowering frontline workers to report and halt processes. At Toyota, any worker can pull the "Andon cord" to stop production when spotting potential issues, allowing problems to be addressed before they cascade into complex failures.
Basic failures result from inattention or disregarding safety protocols. Edmondson recounts her own sailing mishap: casualness after a regatta led to being struck by the boom and thrown into the river. Such errors commonly arise when tasks feel routine and operators think "I can do this in my sleep."
Checklists can prevent basic failures, but only with mindful engagement. The Air Florida Flight 90 crash occurred when crew members went through checklist motions without actual attention—the first officer announced "anti-ice" but the captain responded "habitually off" without confirming the crucial need for de-icing that day.
Edmondson's research on hospital teams reveals that psychological safety—environments where people can report mistakes without fear—is essential for organizational learning. Surprisingly, well-led teams with high ratings for supportive relationships reported more errors, not because they made more mistakes, but because members felt safe speaking up. In authoritarian units where mistakes were met with punishment, staff hid problems out of fear.
Edmondson emphasizes that when failure isn't tolerated, failures don't stop—they just stop being reported. Organizations can't learn from unreported mistakes, so fostering honest communication about errors is the foundation of improvement. Psychological safety ensures problems are caught early, giving organizations chances to remedy errors before harm occurs.
Failure must be managed differently depending on context. The "fail fast, fail often" philosophy popular in Silicon Valley works well for research and development, where frequent experimentation drives innovation within safe laboratory boundaries. Conversely, in operating rooms, airline cockpits, or assembly lines, strict protocols and zero-tolerance approaches are essential—mistakes here can be catastrophic.
Edmondson warns against "lumping all failures into the same bucket." Treating all mistakes the same way leads to poor outcomes. Organizations must discern between intelligent failures inherent to discovery and preventable failures that compromise safety, employing differentiated strategies matched to each context.
Cognitive biases heavily influence financial decisions, often leading prudent individuals into unsustainable debt. John Dinsmore identifies three pervasive biases: optimism bias leads people to assume their finances will improve despite past patterns, encouraging them to take on more debt expecting future income increases. Intertemporal discounting causes people to favor immediate gratification over future consequences, making today's debt feel manageable since payment is postponed. Expense prediction bias leads people to forecast regular expenses accurately but overlook irregular costs like home repairs—Hannah's unexpected $90,000 dry rot repair exemplifies this oversight.
Dinsmore notes these biases contributed to the housing crisis, as homeowners failed to budget for maintenance costs. While debt is often necessary for housing or education, these cognitive distortions can cause even careful individuals to accept unsustainable debt levels when economic conditions shift or costs exceed projections.
Modern markets exploit consumer psychology through tactics like drip pricing, where initial low prices steadily increase with added fees. Dinsmore explains airlines use this strategy, and credit cards reveal hidden costs only after commitment. Maria's timeshare experience illustrates this: salespeople used aspirational presentations to secure $10,000 down, then delivered a 100-page contract with obscure fees buried in fine print.
Marketers exploit aspirations and scarcity to prompt emotional decisions. Dinsmore recounts being talked into expensive drums by a salesperson who fostered dreams of musical success, making the purchase feel like a deserved reward rather than a financial decision.
Beyond manipulation, macroeconomic forces undermine stability. Stagnant wages, rising costs, and inflation create challenges outside individual control. Anna's family bought a fixer-upper following expert advice, but pandemic-driven material cost surges derailed their plans, illustrating how external forces override personal effort.
Dinsmore highlights structural unfairness: those with less money are charged higher interest rates, meaning those least able to bear strain pay more for credit. The psychological impact is crushing—Maria internalized shame after her timeshare loss, questioning her financial savvy despite being otherwise prudent. Anna's sense that "the system was never built for you to win" reflects how people internalize systemic unfairness. Dinsmore encourages self-compassion, reminding listeners that many financial outcomes are shaped by uncontrollable factors and even the most successful suffer setbacks.
1-Page Summary
Mistakes are inevitable in science, work, and daily life, but not all errors are alike. Some failures are trivial, others can be disastrous. Shankar Vedantam and Amy Edmondson explore how understanding different types of failures—intelligent, complex, and basic—can shift setbacks from sources of shame to valuable opportunities for learning and improvement.
Intelligent failures occur at the frontiers of knowledge or personal experience—territories where results are genuinely unknown. Amy Edmondson defines these as the undesired results of forays into new territory, guided by a hypothesis and structured to be as small as possible. Intelligent failures are experiments that, while unsuccessful in outcome, deliver information about what does not work.
Edmondson notes that intelligent failures often happen both at the cutting edge of scientific discovery and in personal ventures, such as trying a new hobby or going on a blind date. She describes how Jennifer Heemstra, a chemist, leads her lab by normalizing failure as part of scientific life, estimating that 90% of well-informed hypotheses at the research frontier result in failure. Each failed experiment gives information about what does not work, enabling rapid revision and further experimentation. This process is likened to wandering in a dark room and discovering, after many attempts, where the door is not—every setback brings you closer to progress.
Blind dates also exemplify intelligent failure: despite preparation and investigation, the outcome remains unpredictable and only trying reveals the answer.
Preparation is key in seeking intelligent failures. Edmondson advises being up-to-date on prior research in science or seeking information about a potential date’s interests. You move forward after doing your homework, and only by acting—by running the experiment or going on the date—can you advance beyond the limits of knowledge.
Edmondson emphasizes limiting the risk of intelligent failures—by scaling them down, you minimize potential waste and avoid catastrophe. For example, after her mother's disappointing weekend visit with a potential match, she agreed to a coffee date with the next prospect, keeping the risk and commitment low. Similarly, pilots are trained using simulators, so failures happen in a safe environment. In organizations, this means setting up experiments or trials where mistakes carry low stakes, ensuring that being wrong does not lead to harm or disaster.
Both Edmondson and Vedantam stress that reframing failures as discoveries rather than deficiencies helps people persevere and innovate. For example, Thomas Edison famously responded to setbacks by saying he had found thousands of ways that did not work, turning each mistake into useful information. This attitude is crucial for growth and learning, especially when pursuing ambitious goals or tackling new challenges.
Not all failures provide useful feedback or occur on the cutting edge. Complex failures happen when multiple, often minor, issues align unexpectedly and lead to major breakdowns in systems that appear otherwise safe.
A tragic example is the 2003 loss of the space shuttle Columbia. During launch, a large piece of foam insulation detached and struck the shuttle’s wing, creating a hole that proved catastrophic on re-entry. Engineers noticed a possible foam strike on launch video and raised concerns, but prior experience with minor foam strikes had led NASA management to dismiss the warning as routine. Their experience taught them that foam strikes usually resulted in minor maintenance, not danger—a belief that proved fatal when this time the defect was worse.
Edmondson introduces the “Swiss cheese model” of failure, where each slice of cheese represents a defensive layer with its own holes (defects). When the holes align, small oversights combine to allow a major error. In a hospital, a chain of small problems—understaffing, inexperience, poor lighting, unclear medication labels—led to a nurse accidentally administering a [restricted term] overdose to a patient. None of the defects alone caused failure, but together they resulted in harm.
Failure Science: Intelligent, Complex, and Basic Failures
Amy Edmondson’s research on hospital teams reveals that fostering psychological safety—an environment where people can report mistakes without fear of punishment—is essential for organizational learning and early error detection.
Edmondson describes a study in which she analyzed different hospital teams using a diagnostic survey measuring the quality of interpersonal relationships, team self-assessment, resources, leadership, and how much team members felt that everyone pulled their fair share. She initially expected that teams with better teamwork would make fewer mistakes. However, the statistical analysis showed the opposite: well-led teams with high ratings for teamwork and supportive relationships actually reported more errors.
Edmondson explains this is not because these teams make more errors, but because they are more willing and able to report errors openly. In well-led, psychologically safe teams, members believe mistakes will not be held against them, so they feel comfortable speaking up. Her research assistant found that in open hospital units, staff said it was easy to talk about mistakes because of what was at stake, like patient health, and they were never afraid to tell others or their managers about errors they observed.
Conversely, in authoritarian units, mistakes were met with punishment. Staff were treated poorly or even “put on trial” for errors, leading to a climate where people hid problems out of fear. Edmondson notes that these differences in interpersonal climate—whether mistakes are stigmatized or openly discussed—directly affect whether errors are corrected or hidden.
A survey question, “If you make a mistake in this unit, it’s held against you,” measured on a seven-point scale, showed that a belief errors would not be punished was significantly correlated with higher reported error rates, reinforcing that a supportive climate leads to more open error reporting.

Psychological Safety in Culture: Enabling Safe Error Reporting to Foster Organizational Learning
Failure is perceived and managed very differently depending on context, and organizations must carefully account for these distinctions to optimize learning and safety.
Amy Edmondson and Shankar Vedantam discuss contrasting approaches to failure in the workplace. The “fail fast, fail often” philosophy, popular among Silicon Valley entrepreneurs, is not universally suitable but works exceptionally well in certain environments like research and development (R&D). In R&D settings, frequent experimentation is necessary for rapid learning and innovation. Many tests will inevitably fail, but these failures are contained within the safe boundaries of the laboratory, limiting risk to the organization while still providing valuable data and insights. Here, constant iteration and learning from mistakes propel new technologies and services forward without risking harm to customers or the public.
Conversely, in critical operational environments such as operating rooms, airline cockpits, or assembly lines, strict protocols and powerful prevention systems are essential. Absolute adherence to standards is paramount to prevent harm, as mistakes in these settings can have catastrophic consequences. Amy Edmondson highlights that in these domains, striving for zero mistakes and adhering to the highest possible standards—“trying our very best to get everything right”—is non-negotiable.
Edmondson warns against “lumping all failures into the same bucket.” Treating all mistakes the same way, such as seeking to completely eliminate failure across all domains, leads to poor organizational outcomes. While experimentation and encourage ...
Embrace Failures in R&d, Eliminate Them In Operating Rooms and Assembly Lines
Cognitive biases heavily influence financial decision-making, often leading otherwise prudent individuals into unsustainable debt or financial distress. Three pervasive biases—optimism bias, intertemporal discounting, and expense prediction bias—shape how individuals approach borrowing, budgeting, and anticipating future costs.
Optimism bias leads individuals to assume their financial fortunes will improve in the future, even if past experience or current patterns offer little evidence for this belief. John Dinsmore points out that people commonly anticipate promotions or increased future income, which encourages them to take on more debt or stretch their finances, expecting their circumstances to get better. This hopefulness can help drive perseverance and action, but it risks leading people into overextension when future events do not offset the present reality.
Because of this bias, people convince themselves they will have more disposable income next year or that things will change for the better, despite consistently having little leftover at the end of previous months or years. This optimism drives acceptance of new loans or financial commitments that may not be sustainable.
While the positive outlook may offer motivational benefits, it also opens the door to financial overextension. People put themselves in tighter financial positions, assuming circumstances will change, and are vulnerable to setbacks if reality doesn't meet their expectations.
Intertemporal discounting manifests when people heavily favor present gratification over future consequences. Dinsmore notes that individuals mentally separate present and future financial realities; today's debt feels manageable since payment is postponed, even if they have a long record of struggling to save or handle similar costs before. Despite never having much financial wiggle room in the past, individuals rationalize that "next year will be different," justifying decisions like incurring unaffordable debt now.
This cognitive distortion allows debt to feel manageable initially, but the stress of mounting future payments soon grows burdensome as reality sets in, undermining long-term financial stability.
As a result, debts taken on under the illusion of improved future circumstances accumulate, often leading to overwhelming burdens when actual costs become due.
Another critical error is expense prediction bias, which refers to the tendency for people to accurately predict regular monthly costs—like mortgages or utility bills—while systematically overlooking irregular or infrequent but significant expenses. Dinsmore observes that home repairs, car breakdowns, and sudden large costs rarely figure into most people's mental budgets.
Shankar Vedantam and a caller named Hannah provide firsthand examples: Hannah’s unexpected dry rot repair cost over $90,000, a sum far outside what she had anticipated as a first-time homeowner. Others may face steep but less catastrophic expenses like broken heating units or roof repairs—still enough to put their finances under considerable strain.
Cognitive Biases in Finance: How Optimism, Intertemporal Discounting, and Prediction Bias Affect Decisions
Modern consumer markets and financial systems use sophisticated tactics to manipulate judgment and exploit psychological and structural vulnerabilities, often leading individuals into debt traps and financial distress.
Businesses frequently use drip pricing, a practice where consumers see an initial low price but encounter additional fees as they proceed with a purchase. John Dinsmore explains that airline tickets are a popular example: while the base fare looks attractive, extra fees for seat selection, priority boarding, and other services steadily increase the final cost. After a psychological commitment to buy, consumers tend to accept these mounting fees.
This approach extends to credit card debt, where consumers initially see just a single interest rate. As they become committed, hidden costs—such as late fees or steeply escalating rates—are revealed and absorbed.
Beyond fees, complexity is deliberately built into contracts and agreements. Maria, a listener, was convinced by salespeople to put $10,000 down on a timeshare, lured by aspirational presentations and the promise of free vacations. Only after committing did she receive a 100-page contract packed with obscure, expensive fees hidden in fine print—details nobody realistically combs through. Dinsmore notes that marketers will highlight positive aspects in simple terms but resort to complexity when obscuring unfavorable conditions.
Salespeople often exploit aspirations and scarcity to prompt emotional decisions, especially among consumers whose identity is connected to lifestyle goals. Vedantam describes how the allure of beautiful brochures and vacation fantasies makes it difficult not to imagine oneself in an enviable lifestyle. Dinsmore recounts being talked into buying expensive drums by a salesperson who subtly fostered dreams of musical success and adoring fans, making him feel seduced by his own aspirations. Marketers frequently present purchases as a deserved reward for hard work, bypassing critical thinking and appealing to emotion.
Cognitive factors further undermine sound financial judgment. Dinsmore points out that background, mood, environment, and skill all play a role in how pricing and complexity influence consumer decisions. The increasingly complex and variable nature of debt pricing—compared to static prices for goods—compounds these effects, often overwhelming even savvy consumers.
Even when consumers are vigilant, macroeconomic forces may thwart financial stability. Stagnant wages, rising healthcare costs, surging house prices, and inflation are cited by Vedantam as challenges that undermine the ability to get ahead. He shares Anna’s story: her family bought a fixer-upper, pursued sweat equity, and followed expert advice, but the pandemic-driven surge in material costs and mortgage rates derailed their dream home, illustrating how external forces can move the goalposts.
Dinsmore acknowledges that many aspects of financial success or difficulty are outside individual control—they are determined by large-scale forces like markets and policy decisions. While policies could be enacted for greater fairness and clarity in debt systems, individuals nevertheless face shifting economic realities that may override personal effort and planning.
Dinsmore highlights structural unfairness in lending. Those with less money, deemed riskier borrowers by financial theory, are c ...
