In this research on impact of smile on persona perceptions with Soon-gyo Jung, João Santos, and Jim Jansen, we find that persona profiles with a smiling photo result in an increase in perceived similarity with, likability of, and willingness to use a persona. However, a smile does not increase the credibility of a persona. Our research has implications for the design of persona profiles and adds to previous findings of persona research that the picture choice influences individuals’ persona perceptions in profound ways.
