The goal of emotional control — feeling calm when you want to feel calm, confident when you want to feel confident, undisturbed when things are going badly — is not just difficult. The research suggests pursuing it actively makes things worse. This is not a comforting message. It is, however, a useful one.

Why trying to control emotions typically intensifies them

James Gross and Robert Levenson’s 1993 research established the foundational finding: suppression — the attempt to inhibit or eliminate an emotional experience — produces a paradoxical intensification of the internal experience it is trying to manage. The outward expression may be reduced. The internal activation is not.

The mechanism was captured by Daniel Wegner’s famous white bear experiment: when people are instructed not to think about a white bear, the thought of a white bear becomes intrusive and persistent. The attempt to suppress a thought directs cognitive resources toward monitoring for its presence — which activates it. Emotional suppression operates through the same mechanism. Trying not to feel anxious requires the brain to continuously check whether anxiety is present, which keeps anxiety active.

There is also a cost that matters directly for entrepreneurship. Suppression requires sustained prefrontal effort to maintain the inhibition of the emotional activation. This depletes exactly the cognitive resources — planning, judgment, strategic thinking — that the founding environment demands most urgently. The entrepreneur who suppresses anxiety before an investor pitch may appear calmer. They are also arriving at the pitch with measurably fewer cognitive resources than before they started suppressing.

The startup/grind culture instruction to “control your emotions,” “stay positive,” and “don’t show weakness” is, neurobiologically speaking, a prescription for making the emotional difficulty worse while spending the cognitive reserves needed to manage everything else. Which is impressive, really, as a set of simultaneous mistakes.

What acceptance actually means — and why it is not passivity

Acceptance, as a formal emotion regulation strategy within Acceptance and Commitment Therapy, is frequently misunderstood. It does not mean approval. It does not mean resignation. It does not mean feeling fine about something difficult.

It means allowing the emotional experience to be present without fighting it — observing it without being consumed by it, without demanding that it change before action can begin.

The mechanism is distinct from both suppression and cognitive reappraisal. Suppression tries to eliminate the emotional experience. Reappraisal tries to change its meaning. Acceptance changes the relationship to the experience while leaving its content entirely intact. The anxiety is still present. What changes is its behavioural grip.

Aldao, Nolen-Hoeksema, and Schweizer’s meta-analytic review found that acceptance-based approaches are consistently more adaptive than suppression across diverse clinical populations and presenting problems. The comparative evidence with reappraisal is more nuanced — under conditions of low-to-moderate arousal, reappraisal is often equally effective. Under conditions of high-intensity emotional activation or somatically-driven emotional states — which is precisely the conditions that entrepreneurship most reliably produces — acceptance outperforms reappraisal.

The outcome that matters: psychological flexibility

Hayes and colleagues’ ACT model identifies psychological flexibility as the primary outcome that acceptance-based approaches produce — and the mechanism through which they produce their performance and wellbeing benefits.

Psychological flexibility is not the absence of difficult emotional states. It is the capacity to act in accordance with one’s values in the presence of those states rather than being directed by them. The emotion is present and felt. It is not, however, making the decisions.

The practical distinction: a founder with low psychological flexibility can only make good decisions when they feel confident, build relationships when they feel energetic, and communicate clearly when they feel calm. The emotional state is a precondition for effective action — which means the inevitable emotional difficulties of founding produce inevitable performance impairment.

A founder with high psychological flexibility feels the fear, the doubt, the exhaustion, and the uncertainty — and still acts with clarity from those states. The emotional experience is present. It is not directive. That difference, replicated across hundreds of decisions per year over the course of building a business, is not a small thing.

Kashdan and Rottenberg’s 2010 review in Clinical Psychology Review established psychological flexibility as a fundamental predictor of health outcomes across diverse clinical presentations. Multiple RCTs have found that increases in psychological flexibility are associated with decreases in psychological problems across depression, anxiety, stress, and PTSD — specifically because the mechanism is transdiagnostic. Changing the relationship to emotional experience, rather than trying to modify the experience itself, works across conditions because the relationship is the common factor.

If the patterns described here resonate as more than theoretical — if emotional states are consistently driving decisions, producing avoidance, or significantly affecting your relationships or your ability to lead — that is worth taking to a professional. A psychologist trained in ACT can work with the specific patterns in your situation. Samaritans are available free at any time on 116 123.

A book worth reading alongside this

Radical Acceptance by Tara Brach is the most widely-read applied treatment of acceptance outside the formal ACT clinical literature. Brach’s synthesis of Buddhist psychology and Western clinical approaches around the theme of what she calls the “trance of unworthiness” — the habitual, automatic refusal to accept one’s own experience as it is — is the most accessible and humane account of why acceptance produces both psychological healing and effective action. For any entrepreneur who has spent significant energy fighting their own emotional life, it is the most honest starting point available.
