In 2016, several prominent athletes kneeled or sat during the national anthem of their games to protest social injustice in America. For their activism, these athletes inconsistently experienced both positive and negative consequences from their sponsors and fans. Therefore, the purpose of this study was to investigate this phenomenon more closely by examining the effect of activism type and activism effort on a sponsor's brand image and purchase intention of a product the athlete endorses, when controlling for brand familiarity. Participants (N = 384) were randomly assigned into groups in a 2 (activism type: safe, risky) x 2 (activism effort: low, high) experimental study. Results indicated brand image and purchase intention were negatively impacted by risky activism compared to safe activism, but activism effort had no effect on the two variables. Further implications and future research are expanded upon in the discussion.
