The PJenga Framework by

Pressure, friction, and acceleration
In the PJenga Framework, structural towers are not static.
They are constantly influenced by forces that move blocks within the system.
Three fundamental dynamics shape these movements.
Pressure
Pressure represents external or internal shocks that stress a system.
Examples include:
• military conflict
• economic crises
• supply chain disruptions
• environmental disasters
• financial instability.
Pressure increases the load on specific structural blocks. When the pressure exceeds the resilience of those blocks, they shift.
⸻
Friction
Friction represents resistance to change.
Institutions, regulations, bureaucracies, and political processes all introduce friction into systems.
Friction can have two different effects.
In some situations, it stabilizes systems by slowing rapid changes.
In other situations, excessive friction prevents necessary adjustments, allowing tension to accumulate until a larger breakdown occurs.
⸻
Acceleration
Acceleration describes mechanisms that amplify and propagate system changes.
Financial markets, digital communication networks, and algorithmic trading systems can transmit shocks across global systems within minutes.
In earlier historical periods, crises often unfolded slowly.
Today, information and economic signals move at digital speed.
Acceleration therefore increases the likelihood that stress in one tower quickly spreads to others.
⸻
The interaction between pressure, friction, and acceleration determines how the PJenga system evolves.
A small disturbance under low pressure may have little effect.
But the same disturbance under high pressure and rapid acceleration can produce cascading instability.
