You should read the actual study [1] then. E.g. "when news on the Panama
Papers broke (the week of April 4th, 2016) and when President Trump called the President of Taiwan (the
week of December 5th, 2016) — two of the highest news peaks during the experiment — Group-AE students
increased their weekly browsing time on the New York Times by 157% and 180% compared to their average
consumption, respectively. Overall, a 10% increase in the share of politically sensitive articles published corresponds to students spending 1.8 more minutes on the website during that week."
