**Claim.** Poor user interface quality on centralized micro task platforms increases both the time workers need per task and their error rate, and both effects lower worker earning ability.

**Type.** mechanism  **Support.** argued

**Holds when.**

- centralized micro task platforms with outdated interfaces

**Source quote.**

> The lacking quality in mechanical turk user interfaces also significantly increases the time for workers to perform tasks and increases the error rate in performing tasks both of which significantly lower worker earning ability on such platforms.
