CORE DEFINITION

Refers to narrow areas such as doorways and corridors. When attackers pass through these areas, they have no cover and are exposed, allowing defenders to easily concentrate fire.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Identify high-risk paths. In the workplace, certain positions (such as the middle layer that takes the blame, or the interface of a department undergoing reform) are 'fatal funnels.' Do not linger in these places. Either pass through quickly or avoid entering altogether.

Anchor fast decisions

The fatal funnel refers to a 'bottleneck passage' in space or organization—where the passer is exposed and without cover, while the defender holds an advantage of overlooking and concentrating fire. The danger arises from geometric asymmetry: the passer's path is fixed and visible, while the defender can pre-position firepower on the flanks and near end. At an abstract level, it is a high-risk node with 'maximum exposure and minimum control.'

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Identify bottleneck points in your path/process (doorways, interfaces, reporting stages). 2. Assess the exposure surface and available cover. 3. Do not linger or accumulate at the funnel. 4. Pass through quickly using speed, dispersion, or preparatory fire. 5. If unable to pass safely, find an alternative route or avoid entering.
