Going Micro to Go Negative? Targeting Toxicity using Facebook and Instagram Ads

Abstract

Spreading uncivil negative campaign messages is a “high-risk, high reward” campaign strategy since certain voters are more likely to be swayed by negative messaging whereas other voters are more inclined to feel sympathy with the attacked. Due to its risks, campaigns may attempt to outsource their uncivil ads to outside groups thus distancing themselves from the negativity and potentially avoiding any backlash. But at a time when advertising platforms boast of their ability to deliver ads to highly targeted audiences, uncivil negative ads could also be optimized to narrowly target citizens to which they are more likely to appeal. To study whether such optimizations are occurring, we retrieve all online advertisements that were placed on Facebook platforms (incl. Instagram) in the seven months prior to the US 2020 election. We perform multilevel ordinal regressions and f ind that ads from off icial political campaigns are more likely to be toxic when targeted at a narrower audience, whereas “dark money” outside groups (like super PACs and non-prof its) are more likely to target broad audiences with their toxicity. In addition, we f ind that ads from outside groups are more likely to be toxic. We discuss the f indings in light of this evidence and ref lect upon future research regarding microtargeting negative messages on online platforms such as Facebook and Instagram.
