Definition: Write the right answer to the question based on the context passage.
Input: It has become increasingly common for academics to use social media to communicate with wider audiences. Twitter, like many other social platforms, typically measures success in terms of numbers of followers, likes and retweets, but this only tells us something about the spreading of messages but not necessarily whether the content of the messages is understood or embraced. One way to ascertain this is through network and language analysis, which, used together, can tell us how effective the communication is.
Economists tweet less, mention fewer people and have fewer conversations with strangers than a comparable group of experts in the sciences, and use less accessible language with words that are more complex, with more abbreviations and with a more distant tone. Their tweets are less personal and less inclusive than those used by scientists.
This is what appeared in April 2017 when we gathered data on tens of thousands of tweets from the Twitter accounts of both the top 25 economists and 25 scientists as identified by IDEAS and Science, including the top three economists at the time, Paul Krugman, Joseph Stiglitz, and Erik Brynjolfsson and, on the other side, the top three scientists, Neil deGrasse Tyson, Brian Cox, and Richard Dawkins. At that time those accounts covered roughly two thirds of all the following.
The timing is significant because 2016 has been declared the year of post-truth politics, the year in which appeals to emotions (pathos) superseded the significance of factual evidence-based information (logos), affecting people's constructions and interpretations of events. This has been accompanied by the growing prominence of political "alt" movements (e.g. UKIP, the Alt-right) and their aggressive, provocative, and populist narratives, and "fake news" leading to political shock events such as Brexit and the Trump election.
The relatively low traction of economists in these public debates has been and continues to be an important issue. Does the public not trust economists? Don't they understand what economists do and how they work? Is their work misrepresented in the media? And how do economists themselves interact with public opinion? Question: Who's tweets' were analyzed?
