Two persepctives to hyper-partisan news
sharing
Shareworthiness factors
“Characteristics of (hyper-
partisan news) which make
articles more or less likely to be
shared on social media.”
(Trilling et al., 2017; Valenzuela et al.,
2017; Xu et al., 2020)
Users‘ motivations for sharing
(hyper-partisan) news
„Different user motivations that drive
sharing processes.“
(An et al; 2013; Marwick, 2018)
3. 4
Shareworthiness Factors
1. Proximity (Bednarek & Caple, 2017; Galtung
and Ruge, 1965; Trilling et al., 2017; Valenzuela
et al., 2017)
2. Conflict (Kim, 2015; Trilling et al., 2017;
Valenzuela et al., 2017)
3. Human interest (García-Perdomo,
Salaverría, Kilgo, & Harlow, 2018; Trilling et al.,
2017)
4. Morality (Neuman et al., 1992; Semetko &
Valkenburg, 2000; Valenzuela et al., 2017)
5. Visual Content (Goel, Anderson, Hofman,
& Watts, 2016; Xu et al., 2020)
4. 5
Motivated reasoning
Ideology-based sharing motivations
attitude-congruent information are favored
over attitude-incongruent information
(Kunda, 1990)
Hypothesis:
“News stories that align with an individual’s attitudes are
more likely to be shared, whereas stories that do not align
with or that are neutral to an individual’s attitude are less
likely to be shared.”

• Infowars.com’s content
distribution on Twitter
• entirely driven by third-party
accounts (accounts of
Infowars & its founder Alex
Jones were banned in 2018)

Methodology - Infowars on Twitter
• Collection of tweets that
contained an Infowars URL
through Twitter’s API
• Excluding tweets that did not fall
into our timeframe
Only (re)tweets that were shared
within 24h after publication
• N = 5,280 tweets
• Collection of Infowars articles
through the GDELT project
(https://www.gdeltproject.org/)
• Time period: Seven days
23/09/2019 – 30/09/2019
• N = 169 articles
• Manually coding of articles into
the 5 hypothesized
shareworthiness factors
(Krippendorff’s alpha = between 0.72
and 0.8)
7. 8
1. What made it into Twitter?
• N = 168 (of 169) were shared on Twitter
2. What was more likely to be tweeted/retweeted?
• How often were articles shared on Twitter? tweet count
• What was retweeted more than what was shared in original
tweets? retweet factor*
*(tweet-count – share-count) / share-count

Methodology - Infowars on Twitter
• Collection of user profile
descriptions that shared an
Infowars.com URL through
Twitter API
1,064 Twitter accounts’ profile
descriptions
• Profile description as a proxy of
user’s political interests
• Accounts without description
(2%) were omitted
• semi-automated clustering
through key-word lists of the
collected profile descriptions:
(see Spierings et al., 2018; Keller, 2020)
• Seven resulting clusters: Trump
followers, Patriots, Infowars fans,
Christians, Military, Pro-gun,
Conspiracy
• Coding of articles in the same
seven clusters (Krippendorff’s alpha =
.62 - .72)

Discussion
• Hyper-partisan news sharing from the original publication
into Twitter: proximity, conflict, and human interest
• Hyper-partisan news sharing from the original publication
within Twitter: human interest
Different factors drive sharing into Twitter compared to
sharing within Twitter
Findings for shareworthiness depend on researchers’
definition and operationalization of shares
Support for the motivated reasoning hypothesis except for
military, pro-gun, and conspiracy clusters
19. 20
Limitations
• Outlet dependency (Infowars)
• Social media platform (Twitter)
• Time frame (one week)
• Selection of shareworthiness factors
• Predictor variables (factors relating to the platform (Twitter)
rather than the source (Infowars) – e.g. follower count of person
sharing or hashtags used)

As profile clusters were mutually exclusive, before conducting regression analyses, we wanted to know how the profile clusters correlate with each other.
We then did the same for the Infowars articles.
