Path Dependence and the Keyboard Example
An economics passage explains path dependence through the QWERTY keyboard: the layout was adopted early and persisted not because it was fastest but because training materials and user habits created switching costs. The author argues that path dependence is strongest when coordination costs are high-when many users must switch together-and weakest when switching costs fall on isolated individuals. The passage notes that Dvorak typists were never more than a small fraction of users and that retraining costs were borne by individuals, not employers.
1. Which new scenario best illustrates the author's claim about when path dependence is strongest?
Read the worked answer
A scenario in which many users must switch together and the old standard persists despite a superior alternative best illustrates the claim-e.g., a city's railway gauge remains because every rail company would have to coordinate a change, even though a different gauge would be more efficient. By contrast, a single firm's software choice that persists because one user finds retraining inconvenient illustrates the weaker case: switching costs fall on an isolated individual. The key variables are coordination costs and who bears switching costs, not merely whether a standard is old.
2. Which finding would most weaken the author's argument?
Read the worked answer
A finding that a superior standard rapidly replaced an inferior one even though many users had to switch together would weaken the claim that high coordination costs make path dependence strongest. For example, if all rail companies switched gauge within a few years once a better standard was demonstrated, coordination costs would not be decisive. The argument does not claim switching never happens; it claims coordination costs strengthen persistence. Evidence of easy coordinated switching would show the mechanism is weaker than stated.
3. How does the QWERTY example function in the argument?
Read the worked answer
QWERTY is an illustrative case, not the conclusion. It makes path dependence concrete: early adoption plus training and habit creates switching costs. The Dvorak detail reinforces the point that being faster is not sufficient to dislodge an entrenched standard. But the author's broader claim is about coordination costs and who bears them; QWERTY is used to show the mechanism, not to prove that every standard is inefficient. A reader should not mistake the example for the thesis.
