$($B$)$ Settling on a single design idea to pursue without exploring the entire space of possible design alternatives.

$($C$)$ Anchoring their new designs too closely to some existing designs rather than re$-$exploring the task$-$specific and the crowd worker$-$specific perspective.

$($D$)$ Involving human workers in early stage of the design rather than waiting until the design is complete and ready for evaluation.

$($E$)$ Brainstorming design alternatives that are technologically or financially unfeasible.
