Business Cognitive Traps: Why Owners Make Worse Financial Decisions in a Crisis

I have spent many years studying questions at the intersection of decision theory, crisis management, and behavioral economics (behavioral finance). During crises—and in my professional career I have lived through several (the Great Recession of 2008, the events of 2014 in Ukraine, COVID in 2019, and the war since 2022)—while working directly with business owners and top management of large holding structures, I have repeatedly observed how executives and owners of very different scales make decisions that are, seemingly, obviously wrong and draw incorrect conclusions. I kept looking for answers. In this article, I try to articulate part of them: which cognitive traps are activated in a crisis, how to recognize them in yourself, and which evidence-based techniques help restore control over your decisions.

This article is not “psychology for psychology’s sake.” It is about which cognitive and neurobiological mechanisms predictably break financial decision-making in a crisis—and which protocols actually reduce the cost of errors. I tried to combine Daniel Kahneman’s classic Prospect Theory with the latest neuroscience data available up to 2025 to show how exactly the brain distorts reality.

1. Why do you lose money when you try to save it?

Why do 73% of owners make their worst decisions precisely when the stakes are the highest? Why does an experienced entrepreneur with 20 years of track record make worse decisions in a crisis than an intern with a calculator? In the Ukrainian reality of a perma-crisis, it looks paradoxical: an owner who thinks rationally “in peacetime” suddenly becomes a hostage to a short horizon, binary choices, and the need to “do something urgently.”

It is not a lack of information and not “stupidity.” The problem is the biochemistry of stress: under chronic strain, the brain switches into short-term survival mode and suppresses strategic thinking. Chronic stress activates evolutionary mechanisms designed for physical survival in the Pleistocene savanna—not for managing a P&L (profit and loss statement) in the digital economy of the 21st century. When you face a cash gap, the risk of staff mobilization, or a logistics collapse, your brain does not see a “business task.” It sees a sabertooth tiger. In response, the hypothalamus triggers a cortisol surge, which effectively disconnects the prefrontal cortex—the area responsible for strategic planning and abstract logic—and hands control to the amygdala, the center of fear and aggression.

You are not “losing your grip.” You are experiencing a biological software failure. In a perma-crisis—a term describing the prolonged instability and lack of safety Ukrainian business has been living in since 2022—this failure becomes chronic.

According to studies from 2024–2025, including reports by Advanter Group and the European Business Association (EBA), Ukrainian business demonstrates a paradoxical dynamic: 77% of companies continue operating at full capacity, yet the sentiment index for small and medium-sized business (MSME) declines, and 59% of owners call “unpredictability” the key factor blocking development. In such an environment, cognitive biases stop being “psychological nuances” and become the main line item of hidden losses.

McKinsey research shows that only 28% of leaders consider strategic decisions in their companies “generally good”—and that is under normal conditions. Under stress, the figure drops even further. For Ukrainian entrepreneurs operating during war, these mechanisms are especially relevant: according to research from 2022–2024, 50% to 73% of the population show symptoms consistent with PTSD, which directly affects the quality of financial decision-making.

2. The anatomy of crisis thinking

To understand the nature of financial mistakes, you must look at the “hardware” on which our decisions run—the neurobiology of the brain under stress.

Chronic stress physically changes the brain architecture responsible for decision-making. This is not a metaphor; it is the result of decades of neuroscientific research.

Amy Arnsten of Yale University described the mechanism in detail in a series of publications:

“Even quite mild acute uncontrollable stress can cause a rapid and dramatic loss of prefrontal cortical cognitive abilities, and more prolonged exposure to stress causes architectural changes in prefrontal dendrites.”
— Amy Arnsten, Professor of Neuroscience, Yale University, Nature Reviews Neuroscience, 2009

2.1. The neurobiology of stress: the HPA axis and the cortisol trap

At the core of the crisis response lies the HPA axis (hypothalamic–pituitary–adrenal axis). When a threat is perceived—whether it is an air-raid siren or a 30% drop in sales—there is a release of glucocorticoids, primarily cortisol. Stress also triggers a massive release of norepinephrine and dopamine into the prefrontal cortex (PFC)—the region responsible for planning, risk assessment, and working memory. High concentrations of these neurotransmitters activate intracellular signaling pathways that literally “switch off” neural networks needed for complex cognition.

Mechanism: In the short term, cortisol is useful: it mobilizes energy. But in a prolonged war and economic turbulence, cortisol remains chronically elevated. A 2025 study by Doroc, K., Yadav, N., & Murawski from the Centre for Brain, Mind and Markets (University of Melbourne), published in Nature Human Behaviour, supports a direct correlation: high cortisol levels are associated with reduced decision quality—especially decisions that are complex and computationally demanding.

Business consequences:

• Atrophy of the prefrontal cortex (PFC). Chronic stress literally destroys neural connections in the brain area responsible for “cold calculation,” long-term planning, and impulse control. You become physically less capable of complex analysis. Working memory suffers first—the ability to hold several variables in mind simultaneously. Cognitive flexibility also deteriorates—the ability to switch between strategies.
• Hypertrophy of the amygdala. The threat-detection center increases in volume and becomes hypersensitive. You begin to see risks where none exist and react to neutral news as if it were a catastrophe. In other words, risk assessment becomes systematically distorted.
• Distorted perception of time. Stress creates a subjective feeling of time scarcity. Even if you have a week to decide on an investment, your brain signals: “Decide now or die.” This leads to impulsive deals or unjustified отказs. Long-horizon consequence planning becomes significantly harder.

2.2. Easterbrook’s hypothesis and the “tunnel vision” phenomenon

Easterbrook’s classic hypothesis (1959), confirmed by modern MRI studies, states: high emotional arousal narrows attentional focus, and the body concentrates resources on the immediate danger. The brain filters out peripheral information to focus on the central threat. For ancient humans, this was lifesaving. The problem is that business threats are not sabertooth tigers. They require the opposite: broad information coverage, multi-variable analysis, and strategic forecasting.

How this looks in the P&L: An owner in a “tunnel” sees only the most obvious problem and focuses exclusively on one metric—e.g., an immediate cash gap and preserving cash flow “here and now.” At the same time, peripheral signals—shifts in consumer preferences, brand erosion, or burnout of key employees—are not registered by consciousness at all. The brain labels this information as “noise.” This is called cognitive tunneling. You “win” the battle for cash this month but “lose” the war for market share next year—because your brain filtered strategically critical information as “noise.”

2.3. Cognitive traps, or the Four Horsemen of the financial apocalypse

Against this neurobiological background, the question becomes: which cognitive traps are activated in a crisis? Four key biases described by behavioral economics bloom—and in a crisis they do not act separately but as a single destructive mechanism. The combination of PFC dysfunction, amygdala hyperactivity, and chronic stress drives owners into predictable cognitive traps.

1) Loss Aversion

Definition: People feel the pain of losing money roughly twice as strongly as the pleasure of gaining the same amount. The psychological pain of losing $100 is equivalent to the joy of gaining $200–250. This is a fundamental principle of Prospect Theory by Nobel laureates Daniel Kahneman and Amos Tversky.

In a crisis: Under stress, the loss-aversion coefficient increases. You may take an irrational risk (for example, refusing to invest in necessary modernization) to avoid a certain expense that the brain encodes as a “loss.”

Numbers: A 2024 meta-analysis confirms that under uncertainty, the weight of losses in the utility function can reach 3:1or even 4:1 compared to gains.

In Ukrainian business practice: This shows up as holding onto loss-making directions (“waiting for a rebound”), refusing to sell an asset below the purchase price, avoiding innovation out of fear of losing current position. The owner continues pouring working capital into supporting loss-making outlets in depressed regions instead of “amputating” the affected part of the business and saving the core. A Journal of Behavioral Finance (2021) study showed cortisol is statistically linked to the disposition effect—selling winners too early and holding losers too long.

2) Sunk Cost Fallacy

Definition: The tendency to continue a loss-making project simply because resources have already been invested (money, time, effort). Richard Thaler describes this as an inability to close a “mental account” at a loss. But the phenomenon has a hard biological substrate: letting go of an asset (realizing a loss) activates the insula—the same region that lights up under physical pain. The brain experiences acknowledging a loss as physical trauma. A 2024 Wharton School study found that attachment to sunk costs reduces the probability of divestitures by 8–9% at the corporate level—even when exit is clearly beneficial.

In a crisis: In Ukraine’s 2024–2025 context, emotional investment mixes with money: “We invested 10 years of life and $5 million into this plant; we can’t abandon it even if it’s under shelling. We kept it running through the 2022 blackouts; we can’t close it.” This escalates commitment: owners keep financing “zombie assets,” draining the healthy part of the business. Research by Marius Guntzel (2024) shows companies systematically fail to ignore sunk costs, reducing investment efficiency.

3) Confirmation Bias

Definition: Actively seeking information that confirms existing beliefs while ignoring contradictory data, or interpreting information to fit an already formed opinion. A neuroimaging study by Andreas Kappes (City, University of London), Ann H. Harvey (Fralin Biomedical Research Institute), Terry Lohrenz, P. Read Montague (Virginia Tech), and Tali Sharot (UCL), published in Nature Neuroscience (2020), showed: the posterior medial prefrontal cortex demonstrates reduced activity when processing disconfirming information. The brain literally filters what it does not want to see.

In a crisis: An anxious brain craves certainty, and confirmation bias intensifies due to information overload: stress reduces the PFC’s capacity for complex processing, and the brain switches to searching only for familiar information.

Practical example: If an owner decides “the war will end in six months,” they will unconsciously ignore any reports or macro forecasts that contradict this scenario. This creates a dangerous illusion of safety and leads to the absence of alternative plans. Business plans are built around beliefs rather than scenario planning.

4) Overconfidence

Definition: Overestimating one’s abilities and forecast accuracy. Dan Ariely notes that we often “sit behind the wheel,” believing we control the situation, while in reality we are controlled by external circumstances and internal impulses.

In a crisis: Paradoxically, the loss of control over the external environment (geopolitics) is compensated by an illusion of hyper-control inside the company. Owners micromanage processes, convinced that only their intervention will save the business—although data show otherwise: 64% of investors overestimate their knowledge, which leads to excessive risk-taking.

5) Status Quo Bias

Definition: Any change requires energy. Under chronic exhaustion (burnout), when neurotransmitter and glucose reserves are depleted, the brain switches into a harsh energy-saving mode. McKinsey research found that resource allocation correlates by more than 90% year-over-year—even when market conditions change radically. Companies that aggressively reallocated resources (top third) generated 30% higher total shareholder returns annually than the bottom third.

In a crisis: Companies keep operating by inertia, using pre-war marketing messages or holding onto toxic clients. The owner understands cognitively that change is needed, but lacks the biochemical resources to initiate it.

3. How biases kill EBITDA

So how do cognitive traps manifest in real business decisions? This is where theory becomes losses when it meets the reality of the Ukrainian market in repeated crises. Consider concrete scenarios.

3.1. Pricing in a crisis: the Loss Aversion trap

Situation: Cost inflation (electricity tariffs, logistics, wages due to talent shortages) is 15% per quarter. The owner of a manufacturing company must raise prices.

Cognitive failure (Loss Aversion): The owner focuses on the risk of losing customers (volume). The pain of a potential customer departure feels intolerable. The brain ignores the alternative risk: losing margin.

“Decision” — fast thinking: “Let’s wait; maybe costs will fall. Or competitors will raise prices first.” Prices are frozen for three months.

Financial result:

• The company operates at minimal or negative margin for a quarter.
• When price increases become inevitable (cash gap), they happen sharply (by ~20%), which shocks customers more than a gradual increase.

Outcome: A 12–18% EBITDA loss over the period that cannot be recovered.

3.2. Downsizing decisions: Sunk Costs + Status Quo

Situation: An IT company with an office in Kharkiv. In March 2022 it received several relocation offers from Western partners. The owner spent three months “analyzing options,” holding meetings, building financial models. Result: some projects were frozen by customers due to war risks; the developer staff (50 people) is underutilized by 40%; payroll “eats” all profit.

Cognitive failure (Sunk Cost + Status Quo): “We built this team for five years. We invested thousands into their training. If we let them go, we’ll never find them again (talent deficit).”

Neurobiology: A classic freeze response—when you cannot fight (Fight) or flee (Flight). Working memory is overloaded with options, and the anterior cingulate cortex locks on the conflict between the need to act and fear of error.

“Decision”: Keep the full headcount, burning reserves (“eating the cushion”) in hopes that contracts return soon.

Financial result: Six months later reserves are depleted. The company is forced into emergency layoffs—after 40% of key developers have already left to competitors—either without severance (destroying the HR brand) or it closes. A rational decision would have been to move part of the staff to part-time or outstaffing immediately, but the “pain of losing” the team blocked it. The company lost a market position that took 18 months to rebuild.

Additional context: According to EBA surveys, talent retention is a key issue for 43% of companies, which often leads to irrational retention of excess staff at the expense of financial resilience.

3.3. Investing in “rescue projects”: Confirmation Bias

Situation: An agribusiness owner decides to build a new grain elevator in a region near the combat zone because land and logistics are cheap.

Cognitive failure (Confirmation Bias): The owner searches for confirmation: “The front line has stabilized,” “Everyone says it doesn’t reach there.” They ignore risk-manager and military-analyst reports about possible escalation or export constraints (grain corridor).

“Decision”: Start construction (CAPEX $1.5M).

Financial result: Four months later logistics is blocked. Construction freezes. Assets become illiquid and uninsurable. $1.5M is locked in concrete (Sunk Costs), and there is no liquidity for the sowing season.

Mini-case: A consumer electronics retail chain, ignoring forecasts of winter blackouts in 2024 (optimism), did not buy energy-independent systems in time. Result: a 40% revenue loss on Black Friday due to store downtime. Opportunity loss: $1.2M with equipment cost of $150k.

3.4. “Saving” a loss-making branch

A manufacturing company in eastern Ukraine. After the full-scale invasion, a branch in a near-frontline zone ran at 30% utilization and generated losses. The owner, instead of relocating equipment, continued funding operations for eight months, investing an additional $400K.

Which traps triggered:

• Sunk cost: “We built this plant from scratch—15 years of life.”
• Loss aversion: realizing the loss meant admitting “defeat.”
• Confirmation bias: “It will end soon; we’ll hold on.”

Result: Equipment was lost during last-moment evacuation; $400K “burned”; the core business ended up in cash deficit.

4. How to recognize cognitive traps in yourself

Awareness is the first step toward detox. Use this checklist to assess the level of cognitive distortion. Answer honestly: “Yes” or “No.” Start with the simplest: Affect check—are you in HALT?

• H (Hungry) — hungry
• A (Angry) — angry/irritated
• L (Lonely) — isolated/lonely
• T (Tired) — tired/exhausted

If yes—postpone any decision for at least 24 hours.

Next: the “Cognitive fever” checklist:

• Sunk cost test: If you entered this business from scratch today, with current knowledge and money, would you buy this asset/project at its current price? (If “No,” but you keep investing—you are in the trap. Most likely you are held by the past, not inspired by the future.)
• Echo-chamber test: Were alternatives considered? Has someone in your team argued against your key decision in the last three months—and you thanked them? (If “No,” you have Confirmation Bias. The decision is postponed and a “devil’s advocate” is appointed.)
• Ostrich test: Do you postpone reviewing detailed financial reports (P&L, Cash Flow) because you “need to gather courage” or “now is not the time”? (If “Yes,” you are avoiding negative information.)
• Control test: Do you believe you can predict the USD exchange rate or the end of the war more accurately than analysts’ consensus? (If “Yes,” Overconfidence.)
• Action test: Do you feel anxious if you are not making decisions every half hour? Do you believe “doing something” is always better than “observing and waiting”? (If “Yes,” Action Bias.)
• Time perception test: Does it feel like all decisions must be made immediately—even if objective deadlines allow a week? (If “Yes,” the cortisol urgency effect.)
• Intuition test: Do you make financial decisions above $50k mostly on “gut feel,” without written justification?
• Past test: Do you often use the argument “We survived 2014; we’ll survive this” to justify strategy—without accounting for the fact that the structure of the crisis has changed?
• Delegation test: Do you believe no one on your team can handle a crisis task as well as you—and you route all flows through yourself?
• Rest test: Do you consider sleep and weekends a “waste of time” during war? (Chronic sleep deprivation amplifies all biases above.)

Interpretation:

• 0–2 “Yes”: You are staying cool-headed. Keep using hygiene protocols.
• 3–5 “Yes”: Risk zone. Your PFC is operating intermittently. You need an external audit of decisions.
• 6–10 “Yes”: “Red zone.” Your ability to make financial decisions is critically impaired. You are in cognitive tunnel mode. Recommendation: impose a moratorium on signing contracts without approval from a CFO or external advisor.

From this context it follows that trigger signals indicate you should involve an outside expert:

• You repeat the same “emergency” pattern (micromanagement, cuts, chaotic pivots) and it does not improve metrics for 2–3 cycles in a row.
• You cannot formulate a clear criterion for closing a project/contract.
• Decisions are made faster than data updates (P&L/CF/NWC).
• You trust “feelings” more than numbers.

5. Which techniques help bypass cognitive traps? Protocols of cognitive hygiene

You cannot force your brain not to react to stress through willpower. But you can build external procedures—“cognitive prosthetics”—that forcibly turn rational thinking back on. Understanding that the problem is biochemical dictates new methods of crisis coping. Instead of abstract calls to “pull yourself together,” you need physiological and procedural interventions.

5.1. Premortem Analysis

A method developed by psychologist Gary Klein and recommended by Nobel laureate Daniel Kahneman. Unlike a “postmortem,” done when the patient is dead, a premortem is done before the project starts. The idea: before launch, the team imagines it is the future—and the project failed spectacularly. Task: write the “failure story.” Why did it happen?

Business algorithm:

1. Setup: Before launching the 2025 strategy, gather the team.
2. Legend: Announce: “Imagine it is December 2025. Our plan failed badly. The company is bankrupt / the product didn’t take off. This is a completed fact.”
3. Assignment: Give everyone 10 minutes to write a “failure story.” Why did this happen? (e.g., “Borders closed,” “Key supplier left,” “Cash gap due to delayed grant.”)
4. Data collection: Everyone reads their version aloud. This legitimizes doubts. An employee who feared seeming pessimistic now becomes a “smart analyst.”
5. Action plan: Select the top 3 threats and design preventive measures.

Effect & neurobiology: This “prospective retrospective” removes the “optimism glasses” and forces the brain to evaluate risks realistically. It no longer needs to defend optimism because failure has already been declared a fact. Research shows premortems improve risk identification by ~30%.

5.2. Red Team / Devil’s Advocate

In an echo chamber, you need a professional dissenter.

Method: Assign a top manager—or invite an external consultant—as the “red team.”

Task: Their goal is to find vulnerabilities in your plan. They must attack your strategy as a competitor or hostile environment would.

Rule: The owner has no right to interrupt or defend themselves until the red team finishes the report. This forces “cold listening.”

5.3. Decision Journal

Memory is deceptive. We tend to attribute successes to genius and failures to circumstances (hindsight bias). A decision journal is an instrument of objectivity.

Template (Notion/Excel):

• Decision essence: (e.g., “Invest $50k into generator procurement.”)
• Expected outcome: (blackout probability 80%, downtime savings $200k).
• Alternatives: (What did I reject? Renting, relocation.)
• Emotional state: (Am I angry, tired, panicking?)—critical to track stress influence.
• Review date: (Re-check in six months: was the forecast correct?)

5.4. The 10/10/10 Rule

A simple heuristic by Suzy Welch to fight tunnel vision and impulsivity.

Before a hard decision (e.g., firing a toxic but effective executive), ask:

• How will I feel about this decision in 10 minutes? (Removes acute emotional spike.)
• How will I feel about it in 10 months? (Turns on the tactical horizon.)
• How will I feel about it in 10 years? (Turns on the strategic/values horizon.)

Example: firing

• 10 minutes: fear, panic, “who will do the work?”
• 10 months: relief, team cohesion, processes stabilized.
• 10 years: pride for not compromising values.

Conclusion: fire.

5.5. An external consultant as a “cognitive prosthesis”

An external expert is useful not because they are smarter. Their value is that their amygdala is not triggered by your problems. Grossmann & Kross (2014) in Psychological Science documented the “Solomon paradox”: people reason more wisely about others’ problems than their own.

“Participants demonstrated wiser reasoning—recognition of the limits of one’s knowledge, the importance of compromise and change, and the consideration of others’ perspectives—about another person’s problems than about their own.”
— Igor Grossmann, Ethan Kross, Psychological Science, 2014

By bringing in a consultant, the owner effectively “rents” an active dorsolateral cortex to solve tasks that are blocked by their own limbic system.

6. FAQ: Answers to uncomfortable questions

Q1: I don’t have time for “journals” and “premortems.” I’m firefighting 24/7.
A: You are firefighting precisely because six months ago you didn’t do a premortem. “Cognitive hygiene” takes 30 minutes. Fixing the consequences of one wrong investment decision (sunk cost escalation) takes months and costs millions. In a crisis, “slow is fast.”

Q2: Isn’t intuition more important during war? Data becomes outdated instantly.
A: Intuition is “crystallized experience.” It works well in stable environments (chess, tennis) where patterns repeat. War and perma-crisis are chaos. Your experience from the 2010s is not relevant for 2025. In a new environment, intuition is uncalibrated and dangerous. Trust protocols, not your stomach.

Q3: How do I distinguish “grit” from the sunk cost trap?
A: Grit is loyalty to the goal (e.g., to keep the business). The sunk cost trap is loyalty to the method (e.g., to cling to a specific branch). Ask: “If I were an external consultant hired today, would I close this project?” If the answer is “Yes,” and you don’t close it—you are in the trap.

Q4: Won’t premortems and failure modeling demotivate the team?
A: The opposite. Uncertainty breeds anxiety. When a leader honestly names risks and shows there is a Plan B, collective anxiety drops. People see: “The captain sees the iceberg and knows how to steer,” not “The captain lives in illusions.”

Q5: Are these biases specific to Ukrainian businessmen?
A: Biases are universal to humanity—this is brain “firmware.” But the Ukrainian context (existential threat) is a powerful catalyst. Where a Western CEO loses a bonus, a Ukrainian CEO risks everything. Higher stakes → stronger distortions.

Q6: Can the brain be trained to resist cognitive traps?
A: Yes, partially. Morewedge et al. (2015) in Psychological Science showed that even one-off debiasing training yields a ≥31% immediate reduction in susceptibility, with effects of ≥23% persisting for 2–3 months. However, Kahneman emphasizes: “I am much more optimistic about organizations than individuals. Organizations can implement systems that help them.”

Q7: Why don’t I notice my own cognitive biases?
A: Because that is their function. Confirmation bias makes the brain seek confirmation, not refutation. Loss aversion disguises itself as “caution.” Sunk cost fallacy feels like “responsibility.” The brain protects its heuristics because they save energy.

Q8: Do I need a consultant if I have an experienced internal team?
A: An internal team is subject to groupthink. Employees’ mirror neurons are tuned to read the leader’s emotions and adapt to them. If the leader panics, the team mirrors it. An external expert is not embedded in the hierarchy and can introduce a “prediction error”—information that contradicts the owner’s brain expectations.

7. Conclusion

War and crisis are not only a battle of resources, logistics, and people. They are a battle for clarity of mind. The main asset of your business in 2026 is not machinery and not cash on accounts. In a crisis you do not become “a worse leader”—you become predictably more vulnerable to cognitive traps because the brain’s operating mode changes. It is the neural network in your head that makes decisions.

Chronic stress tries to turn you from a Strategist into a Survivor. The Survivor hides money under the mattress, fears change, and clings to the past. The Strategist assesses risks, realizes losses without regret, and invests in the future. Recognizing the neurobiological reality—that chronic stress physically changes decision architecture—is the first step toward resilience. “Cognitive traps” are not character defects; they are predictable glitches of an overheated system. In these conditions, using an external consultant is not a luxury but a safety protocol. Combined with cognitive hygiene techniques (premortem, breathing regulation, scenario planning), it creates the foundation for survival and development even in perma-crisis.

The best action algorithm for tomorrow:

1. Acknowledge biology. You are not Iron Man; cortisol affects you like everyone else.
2. Audit your decisions. Run your last three major decisions through the checklist.
3. Install an external “controller.” Find a mentor, consultant, or build an advisory board so someone with a “cold” brain looks at your numbers.
4. Kill one “zombie.” Close one project that is pulling you backward, ignoring the resources already spent on it.

In a perma-crisis, the winner is not the one who runs faster—but the one who realizes faster that they are running in the wrong direction and changes course.
