Democracy’s vulnerabilities

My experience of RCA derives from its application within mental health services, particularly in the review of adverse events where outcomes have deviated from intended or expected standards of care. A central principle of this approach is the establishment of a “no blame” culture. Within this framework, errors are not automatically attributed to individual failure; rather, they are understood as arising from systemic conditions that may constrain, shape, or limit individual performance.

The objective is therefore to identify systemic failure rather than isolated human error. A commonly used technique in this process is iterative questioning—often referred to as the “Five Whys” method—in which repeated interrogation of causation is used to move beyond surface-level explanations towards deeper structural determinants of failure. This approach recognises that adverse outcomes are typically the result of multiple interacting factors rather than a single causal event. The “Swiss Cheese Model” is frequently used to conceptualise this, illustrating how failures occur when multiple layers of defence are breached due to the alignment of latent vulnerabilities.

The core principles underpinning Root Cause Analysis can be summarised as follows:

  • A fundamentally “no blame” culture: individual error is not presumed; instead, the focus is placed on understanding how system conditions shape behaviour and decision-making.
  • A strict system-oriented perspective: analysis prioritises structural, procedural, and environmental contributors over personalised attribution of fault.
  • Presumption of non-malicious intent: errors are generally interpreted as arising within constraints and system pressures, unless clear evidence indicates otherwise.
  • Structured iterative inquiry (“Five Whys”): disciplined repetition of questioning is used to progress from proximate causes to underlying systemic drivers.
  • Recognition of multifactorial causation: outcomes are understood as emergent properties of interacting and compounding factors rather than single-point failures.
  • Swiss Cheese Model of defence-in-depth: system failure is conceptualised as the alignment of weaknesses across multiple layers of protection, allowing hazards to pass through unchecked.

For the purposes of this analysis, the “serious untoward incident” is defined as: why democracy is perceived to be underperforming relative to its intended principles and societal expectations.
