CORE DEFINITION

The QWERTY keyboard layout was originally designed to slow down typing speed (to prevent mechanical jams), and although this technical limitation no longer exists and more efficient layouts (like Dvorak) exist, the inferior standard still dominates the world due to huge switching costs and network effects.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Lock-in from first-mover advantage. Once a standard (even a suboptimal one) occupies a niche and forms user habits, technical superiority is hard to beat it. When making products, either be the first to define the standard, or be good enough to cover users' switching costs.

anchor

Anchor fast decisions

Inferior standards form a positive feedback loop through first-mover advantage, network effects, and switching costs. Once popular, they self-reinforce and become difficult to replace by superior alternatives (lock-in). Technical superiority cannot overcome ecological inertia; first movers / established standards hold structural advantages.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Assess the network effects and switching costs of a standard/technology.
Determine if there is 'suboptimal lock-in'.
If creating a new standard: either define it first, or be good enough to cover switching costs.
If already behind: find a compatible / gradual replacement path.
