Although personas have been applied for two decades, not much is known about why a designer chooses a specific persona for a given design task. This question matters because if designers prefer one persona over another, then the needs and attributes of that persona would be favored in the design process, resulting in possible “blind spots” and bias in regards to other personas. To explore reasons and behaviors associated with the choice of a persona, we conduct an on-site user study with 37 participants in a workplace setting focused on a social media content creation task. Our findings show that factors affecting the choice of persona include age similarity between the persona and the designer, persona’s looks, how many users the persona represents, time spent browsing the persona information, and whether the persona is (a)typical relative to other personas. Under different persona sets, these factors were correlated with the probability of a persona being chosen for a design task, and also supported by a qualitative analysis of the think-aloud records where the participants explained their persona choice. The findings provide implications for developing interaction techniques that support users’ varying information needs and persona selection strategies, including recommenders that would increase the match between the designers’ information needs and the available personas.
