Your Judgement Is State-Dependent. Your Calendar Should Reflect That.
The same leader, the same information, two different physiological states — and two different decisions. Most executives manage their time. Very few manage the state they make decisions in.
In short
Physiological state changes how information is interpreted, how much ambiguity feels tolerable, how quickly you react and how much bandwidth is available for competing perspectives. This means the same leader, with the same facts, can reach different conclusions depending on what happened in the two hours beforehand. Most executives manage their time carefully and their state not at all — which leaves a significant and unmanaged variable sitting directly upstream of every important decision.
A managing director I worked with had a rule he had arrived at himself, without any psychological input, purely from observation.
He would not make hiring decisions after 4pm.
He could not fully articulate why. He had simply noticed, over several years, that the calls he made late in the day were systematically different from the ones he made in the morning — quicker, more categorical, more likely to be about whether he liked the person than whether they could do the job. Same candidates. Same information. Different outcomes.
He had discovered something that turns out to be quite well supported: judgement is state-dependent.
What state actually changes
It is tempting to think of physiological state as something that affects how you feel, sitting alongside the real work of thinking. That is not quite how it operates.
Your state affects:
• how you interpret ambiguous information — whether a short email reads as efficient or hostile
• whether uncertainty feels workable or threatening
• how fast you move from stimulus to response
• how much bandwidth is available to hold competing perspectives simultaneously
• how much of the context you can keep in view at once
• the tone you bring into a room before you have said anything
Under acute stress, working memory and cognitive flexibility become less reliable on average. The effect is not that thinking stops — that framing is overstated and worth resisting — but that it becomes harder to hold several pieces of information at once, update an interpretation as new facts arrive, or inhibit the response that showed up first.
There is also evidence that stress shifts control towards habitual rather than goal-directed action. Under load, you become more likely to do the thing you usually do, and less likely to do the thing the situation specifically calls for.
For most roles this is a minor inefficiency. For a leadership role, where the primary output is judgement, it is the whole product.
The decisions that get made in the wrong state
In practice, this shows up in fairly predictable places.
The reply sent eleven minutes after the email that annoyed you — a decision made at peak activation, in writing, permanently.
The performance conversation scheduled directly after the board meeting, because that was the gap in the calendar.
The strategic discussion held at 5:30pm because everyone was available, with everyone at their least able to hold ambiguity.
The hiring call at the end of a day of hiring calls.
The decision about whether to escalate a conflict, made while still in the conflict.
None of these are unusual. They are ordinary calendar behaviour. And in each one, a significant variable sitting directly upstream of the decision is being left entirely unmanaged.
Two failure modes, not one
Most discussion of stress and performance assumes a single direction: too much activation, therefore worse decisions. That is only half of it.
Over-activated judgement
Fast, categorical, low tolerance for nuance. Threat gets over-read. Ambiguity gets resolved prematurely because sitting with it is uncomfortable. The decision feels decisive from the inside and often reads as impatient from the outside.
The characteristic error is acting too soon on too little.
Depleted judgement
Flat, slow, disengaged. The path of least resistance wins. Options are not generated because generating them requires energy that is not available. Things get deferred not because deferral is right but because deciding is effortful.
The characteristic error is defaulting — which is still a decision, just one nobody made deliberately.
These two need opposite interventions, which is why generic advice to "take a breath" is unhelpful roughly half the time. Someone who is already depleted does not need further slowing.
Managing state as an executive discipline
This does not require a wellbeing programme. It requires treating state as a variable you already manage badly and could manage better.
Sequence, don’t just schedule
Most executive calendars are optimised for availability. Almost none are optimised for state.
Where in the day are the decisions that genuinely require nuance? What sits immediately before them? A leader who moves the difficult performance conversation from directly-after-the-board-meeting to first-thing-Wednesday has done more for the quality of that conversation than any amount of preparation.
Build a gap where the stakes are highest
The most valuable ninety seconds in an executive day is often the one immediately before a high-stakes interaction, and it is usually spent walking between rooms while reading something else.
Ninety seconds of doing nothing in particular — standing still, feeling your feet, looking at something further than two metres away — is not a wellness ritual. It is putting a gap between the previous state and the next decision.
Know which way you are off
Before something that matters, the useful question is not "am I stressed" but "which direction am I off in?" Wired, or flat?
Wired usually needs less input, firmer physical contact, and an easier exhale. Flat usually needs the opposite — movement, light, upright posture, sound.
This is the distinction Soma Circuit is built around: rather than offering one generic calming exercise, it asks which state you are actually in and matches the practice to it. I built it because the two states genuinely need opposite things, and treating them the same is the most common mistake in this territory.
Install a rule rather than relying on judgement
The managing director with the 4pm rule had the right instinct. The point of a rule is that it does not require good judgement to apply — which matters, because the moments when your judgement is compromised are exactly the moments when you are least able to notice.
No consequential decisions in the first twenty minutes after conflict. No sending anything written while activated. No hiring calls after a certain hour. Whatever the pattern is for you, a rule outperforms an intention.
The version of this that goes wrong
Two cautions, because both are common.
The first is turning state management into another optimisation project — tracking, scoring, another dashboard, another thing to be inconsistent at. That reliably becomes a source of pressure rather than a relief from it, and the irony is not subtle.
The second is using this framing to relocate a structural problem into an individual one. If a leadership team is making poor decisions because it is chronically under-resourced and permanently in crisis, the answer is not that its members should regulate better. Individual state management is a real lever, and it is a small one compared with what the conditions are doing.
The variable nobody is managing
Executives manage time obsessively. Many manage attention. Rather fewer manage energy.
Almost none manage the physiological state they are in at the moment of decision — despite it sitting upstream of interpretation, tolerance for ambiguity, reaction speed and available bandwidth.
You would not sign something important while drunk. Most senior people sign things every week while depleted, activated, or twenty minutes out from a conflict, and treat the resulting decisions as though they came from the same person who would have made them on a Tuesday morning.
They did not, quite.
The state you are in is part of the decision. It may as well be a considered part.

Frequently asked questions
What does state-dependent decision making mean?
It means the same person, with the same information, can reach different conclusions depending on their physiological state. State affects how ambiguous information is interpreted, whether uncertainty feels workable, how fast you move from stimulus to response, and how much bandwidth is available for competing perspectives.
How does stress affect leadership decisions?
Acute stress makes working memory and cognitive flexibility less reliable, and shifts control towards habitual rather than goal-directed action. Practically: it becomes harder to hold several considerations at once, update an interpretation, or resist the first response — and more likely that you do what you usually do rather than what this situation needs.
Are there two kinds of poor decision state?
Yes, and they need opposite responses. Over-activated judgement is fast and categorical, resolves ambiguity prematurely, and errs by acting too soon. Depleted judgement is flat and disengaged, takes the path of least resistance, and errs by defaulting. Advice to slow down helps the first and worsens the second.
What can a leader actually do about this?
Sequence the calendar so that decisions requiring nuance are not placed directly after depleting events, build a ninety-second gap before high-stakes interactions, identify which direction you tend to be off in, and install rules rather than relying on judgement — since compromised judgement cannot reliably detect itself.
Isn’t this just wellbeing rebranded as performance?
The framing matters less than the mechanism. State sits upstream of interpretation, reaction speed and available bandwidth, so for a role whose primary output is judgement it is a performance variable regardless of what it is called. The caution is that it should not become another optimisation project, or a way to relocate structural problems onto individuals.
