Although often seen as a gold-standard, human labeled training data is not error free. Decisions in the design of labeling tasks can impact the resulting labeled data and impact predictions. Building on insights from survey methodology, a field that studies the impact of instrument design on survey data and estimates, we examine how the structure of a hate speech labeling task affects which labels are assigned. We also examine what effect task ordering has on the perception of hate speech and what role background characteristics of annotators have on classifications provided by annotators. The study demonstrates the im-portance of applying design thinking at the earliest steps of ML product development. Design principles such as quick prototyping and critically assessing user interfaces are not only important in interaction with end users of an artificial intelligence (AI)-driven products, but are crucial early in development, prior to training AI algorithms.
