CORE DEFINITION

The Dvorak keyboard layout is far more efficient than QWERTY (reducing finger travel distance by about three times), yet because QWERTY has formed an ecosystem monopoly, the superior Dvorak has never been able to gain widespread adoption.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

"Better" does not equal "more successful." When promoting a product or standard, do not assume that superior technical metrics (like typing speed) will ensure victory over competitors. You must calculate users' switching costs and ecosystem lock-in. If switching costs exceed the benefits of efficiency gains, users will never move.

Anchor fast decisions

The Dvorak layout is far more efficient than QWERTY (reducing finger travel distance by about three times), yet it has never been widely adopted due to QWERTY's ecosystem monopoly, illustrating path dependence where a historically accidental lock-in sustains an inferior equilibrium.
