Making Decisions Under Pressure: What Decision Science Shows

Many of the decisions that define a leader's tenure are made under pressure: a major customer threatens to leave, a system fails, a deadline arrives with key facts still missing. Pressure does not just make decisions feel harder. It changes how people process information.

Decision science offers practical guidance here: what pressure does to judgment, when fast intuition can be trusted, and how to build processes that hold up when you cannot think as clearly as you would like.

What pressure does to thinking

In a 2009 review in Nature Reviews Neuroscience, Yale neurobiologist Amy Arnsten wrote: "Even quite mild acute uncontrollable stress can cause a rapid and dramatic loss of prefrontal cognitive abilities." The prefrontal cortex supports the flexible, goal-directed thinking leaders rely on. Under stress, Arnsten explains, attention shifts from thoughtful "top-down" control toward more reflexive "bottom-up" control, and responding tilts toward habit. Much of the mechanistic evidence comes from animal studies, alongside human research.

One detail matters for leaders. The review notes that people "who felt in control of the situation (even if this was an illusion) were often not impaired by stress exposure, whereas those who felt out of control were impaired." A sense of control, such as a plan, a clear role or a known next step, appears to be protective.

In human decision experiments, the effects are real but modest. A 2016 meta-analysis in Psychological Bulletin by Starcke and Brand pooled 32 datasets with 1,829 participants. Laboratory stress led to decisions that were more disadvantageous, more reward-seeking and more risk-taking, with a small overall effect (d = .17). The effect was larger in situations where taking more risk was the wrong move (d = .26) and absent in situations where it was not.

A 2016 review by Yu in Neurobiology of Stress proposed that stress shifts people from deliberate analysis toward intuitive processing. It summarized evidence that stressed individuals tend to make more habitual responses, are less likely to adjust an initial judgment and rely more on gut feelings in social situations.

The practical upshot: under pressure, you are more likely to anchor on your first read, reach for a familiar playbook and accept risks you would question on a calm day.

When to trust your gut

That does not make intuition the enemy. Naturalistic decision making (NDM), a research approach that, as Gary Klein describes in a 2008 Human Factors article, emerged in the 1980s to study decisions in real-world settings, emphasizes how experience lets people rapidly categorize situations and act effectively.

In a 2009 American Psychologist article, Daniel Kahneman and Gary Klein set out to reconcile two approaches often seen as conflicting: the heuristics-and-biases tradition and NDM. They concluded that judging an intuition's quality requires assessing how predictable the environment is and whether the person has had the opportunity to learn its regularities. As they put it: "Subjective experience is not a reliable indicator of judgment accuracy."

Questions to ask before going with your gut:

1. Have I faced this kind of situation many times, with clear feedback on how my calls turned out?
2. Is this environment regular enough that past patterns predict what happens next?
3. Is my confidence coming from expertise, or from urgency?

A seasoned operations leader handling a familiar type of outage may have earned that intuition. The same leader sizing up an unfamiliar acquisition or a one-of-a-kind crisis has not, however confident they feel.

Sort the decision before you make it

Not every urgent decision deserves the same treatment. In his 2015 letter to Amazon shareowners, Jeff Bezos distinguished "one-way door" decisions, consequential and irreversible or nearly so, which "must be made methodically, carefully, slowly," from reversible "two-way door" decisions that "can and should be made quickly."

Under pressure, ask: if this turns out to be wrong, can we undo it? If the answer is "we adjust next week," decide quickly and set a review point. If it is "we can't take this back," buy what time you can, even an hour, and bring in someone to challenge you.

Waiting is not automatically safe, either. U.S. Army command and control doctrine (ADP 6-0, July 2026) puts it this way: "Waiting for perfect intelligence and synchronization may increase risk or close a window of opportunity." The same doctrine distinguishes reasonably estimating and accepting risk from gambling.

Build the process before the pressure

Because pressure narrows thinking, the best time to prepare is before it arrives. Checklists are a well-studied example. In a 2009 New England Journal of Medicine study, Haynes and colleagues introduced a 19-item surgical safety checklist in eight hospitals in eight cities. The death rate fell from 1.5% to 0.8%, and inpatient complications fell from 11.0% to 7.0%. The study compared periods before and after the checklist, so it shows an association rather than proof that the checklist alone caused the change. Still, it illustrates how a short, shared routine can support performance when attention is stretched.

For a leadership team, the equivalent might include:

• A crisis checklist: who convenes, who decides, who communicates and which facts to gather first.
• Pre-agreed decision rights, so people know which calls they can make without waiting; see our guide Delegation for Senior Leaders: What to Hand Off and What to Keep.
• Escalation thresholds written in advance, such as a dollar amount, a customer-impact level or a safety trigger.
• A designated challenger role for high-stakes calls.

A short protocol for the moment

1. Name the decision and the real deadline. Many "right now" decisions actually have hours or days.
2. Ask whether it is reversible.
3. List what you know, what you don't, and what would change your mind.
4. Generate at least one alternative to your first idea.
5. Ask one person to argue the other side.
6. Decide, explain your intent and set a time to review.

For example, imagine a hospital system vice president who learns at 4 p.m. that a key supplier will miss a delivery. Her first instinct is to sign an expensive emergency contract. Using the protocol, she confirms the real deadline is the next morning, asks the purchasing lead to make the case for a cheaper alternative and schedules a 9 a.m. review. She may still sign, but now it is a choice rather than a reflex.

After the pressure passes

Kahneman and Klein's work suggests intuition improves only where there is a real opportunity to learn. After significant decisions, briefly review what you knew, what you decided and what happened, so future gut calls rest on feedback rather than memory.

Sustained pressure is different from a hard day. If stress is affecting your sleep, health or mood over time, talk with a qualified professional; decision tools and coaching are not a substitute for professional care. If you or someone you know is in crisis, call or text 988 in the US.

Key takeaways

• Acute stress can impair flexible, prefrontal thinking and nudge decisions toward habit and risk-taking, though lab effects on decisions are modest on average.
• A sense of control appears protective, so clear roles and plans matter most in a crisis.
• Trust intuition only in predictable environments where you have had real feedback; feeling confident is not evidence.
• Sort decisions by reversibility: move fast on two-way doors and slow down on one-way doors.
• Build checklists, decision rights and escalation thresholds before you need them.
