F – ADRENALINE Responses

FIB

Concealing guilt

Fibbing is an emergent protective response and is increasingly recognized as an adrenaline‑based survival strategy alongside the more familiar Fight, Flight, and Freeze patterns.

With the development of complex and advanced language—something our early ancestors did not possess—humans gained the ability to verbalize both factual and fictitious reasoning instantaneously in moments of stress or perceived threat.

A fib can function as a rapid, neurologically driven safety behavior rather than a sign of intentional dishonesty. Many neurodivergent individuals—especially those with a PDA profile—demonstrate a fourth pattern: Fabricate! When the nervous system senses threat, overwhelm, or a potential loss of autonomy, the brain’s language centers may activate faster than conscious reasoning. This can produce instant explanations, diversions, or narratives designed to reduce pressure and restore a sense of safety.

A PDA‑affirming example of this response might involve a child or adult quickly saying “I already did it,” “I didn’t hear you,” or offering an elaborate explanation when faced with a demand that feels too intense. What may appear as intentional lying is often one’s own nervous system scrambling to reduce internal pressure, preserve autonomy, and avoid what feels like an overwhelming expectation.

From an evolutionary standpoint, this is logical. Once humans developed complex language, verbal strategies became just as protective as physical ones. A quick fib can regulate adrenaline, avoid confrontation, and maintain autonomy—particularly in environments where direct refusal feels unsafe. Rather than a moral failing, it is a survival response emerging from one’s own highly sensitive threat‑detection system.
