Introduction

Every mediator eventually encounters a case that ends abruptly. When that happens early—before offers are exchanged or meaningfully considered—it can feel unsettling for everyone involved. Lawyers may view the decision as irrational. Parties may experience it as morally necessary. Some mediator’s may view it as a failure on their part. From this mediator’s perspective, however, these moments often reflect something more fundamental: a temporary loss of capacity for deliberative decision‑making. This article blends mediation practice, conflict theory, and neuroscience to explain why some mediations cannot continue in the moment, why termination may be ethically required, and how mediators and lawyers can respond constructively when a party becomes emotionally dysregulated.

A Familiar Mediation Scenario

The mediation underlying this discussion involved a same‑sex divorce with relatively conventional legal issues: classification of property, allocation of debt, and the possibility of an unequal division based on circumstances within the marriage. One party was prepared to move forward with negotiations, but the other party felt deeply wronged and sought financial redress for perceived inequities during the marriage. Before the mediation could meaningfully unfold to explore the underlying feelings, one party who felt "wronged" abruptly terminated the process—without responding to an initial offer. From a legal standpoint, the decision was improvident and impulsive. From a neurobiological standpoint, it was predictable, if not inevitable.

Amygdala Hijack: What the Science Says

The term “amygdala hijack,” popularized by Daniel Goleman, describes a rapid neurological process in which the brain’s threat‑detection system overrides the prefrontal cortex. Joseph LeDoux’s foundational research demonstrates that emotional responses can bypass conscious cognitive processing entirely. When a person experiences perceived threat—such as injustice, humiliation, loss, or fear—the amygdala activates first. Stress hormones flood the system, neural resources shift away from the prefrontal cortex, and the brain prioritizes defense over deliberation.

Why Reasoning Fails Under Emotional Flooding

Neuroscientist Amy Arnsten has shown that stress hormones directly impair prefrontal cortex functioning, weakening working memory, impulse control, and cognitive flexibility—the very capacities mediation depends on. Under conditions of uncontrollable stress, the brain’s regulatory systems are effectively taken offline.

A dysregulated party may appear articulate or resolute, yet remain neurologically incapable of evaluating risk or compromise.

How Long the Brain Needs to Recover

Contrary to common assumptions, emotional regulation does not immediately restore judgment. Bruce McEwen’s research demonstrates that stress hormones can impair cognition long after outward calm returns. Judgment impairment often persists for 24–48 hours, and full neurochemical regulation may take several days.

Mediator’s Proposals and Re‑Engagement

Offering a mediator’s proposal after termination aligns with institutional ADR best practices. The U.S. Air Force ADR Program recognizes that effective reality‑testing often requires a period of temporal distance from peak emotional arousal. A structured proposal allows parties to re‑engage once judgment returns—or to decline without coercion.

Conclusion

Mediation does not fail because emotion appears. It fails only when we pretend emotion does not matter. Sometimes the most responsible thing a mediator can do is recognize when the brain is offline—and wait until it comes back.
