Humans and algorithms work together — so study them together

Later this year, the US Supreme Court will rule on a case with profound implications for society and technology. The case centres on Nohemi Gonzalez, a US student who in 2015 was shot and killed by the Islamist terrorist group ISIS in Paris. Her father claims in the suit that Google, which owns the video platform YouTube, should be held responsible for permitting the platform’s recommender algorithms to promote content that radicalized the terrorists who killed Gonzalez. The final ruling, expected by the end of June, could make digital platforms liable for their algorithms’ recommendations.
