Fragmentation of identity through structural holes
in email contacts

Research QuestionsHow does social network structure
impact individual construction of identity?
How is this behavior made explicit online?
How can this be observed within the context of email?

Construction of Individual Identity
Interrelated ideas of identity– Social identity: public presentation of self– Internal identity: private view of self
Fragmentation vs. Multi-Faceted Identity– Fragmentation: conflicting internal identity– Multi-faceted: coherent internal identity,
fragmented social identity

Managing Faceted SelvesDifferentiated presentation changed according to
context– How? Fashion, language, location/context, people – Why? Privacy, social appropriateness, reputation
differentiation– Who? Dependent on self-monitoring habits,
marginalization, fear of retributionFragmented social network (e.g., work, clubs,
family, …) – Separate social circles provide for segmentation of
presentation

Identity onlineConfusion of context
– Ease of moving between multiple contexts
– Data aggregated across “locations”Email address serves as context
– Allows for privacy and faceted behavior

Relating Network Structure
Structural holes & bridges (Burt)– Maximize & control information flow
Simmelian ties (Krackhardt)– In public settings, personally
constraining by restricting appropriate behavior – aggregate of all associations
Control of network structure– Minimize uncontrolled personal
information flow

Structuring social networks via email
Recognizing the power of multiple recipients– Copy/paste phenomenon to appear
personal or contextual– Slight content alternations for context– Making others aware of audience

Ego-Centric VisualizationVisualization tool to observe social
networks embedded in email– Focused on structure
Analyzed “Mike’s” email habits– 5 years worth of complete data– Maintains multiple email addresses for
different contexts– (Dis)advantages of using one person’s
behaviors

Introducing MikeSocial characteristics:
– 24-year old, gay-identified, white male– Born in northern CA, attended Yale (art &
computer science)– Friends & jobs in: Boston, SF, Chicago, NYC– Uses many forms of media to stay connected
Mike’s primary social communities:– Family, high school friends– Undergraduate friends – Gay men in/outside Boston, in NYC– Boston, Texas, California work colleagues

Mike’s dataset80,941 messages
– 1.03 average recipients per msg15,537 unique people
– 7,250 people w/ 2,618 knowledge ties (excluding listservs)
– 662,078 ties between all respondents (using only messages with <50 recipients; otherwise, 11.7 million)
– 226 trusted ties; 23 reciprocal

Defining ConnectivityKnowledge ties
– If A sends a message to B, A ‘knows’ B– B does not necessarily know A
Awareness ties– If B receives a message from A -> B is ‘aware’ of A– If B and C both receive a message from A -> B and C
are ‘aware’ of each otherTrusted ties
– If A sends a message to B and blind carbon copies (BCC’s) D -> A ‘knows’ and ‘trusts’ D
– (D has the ability to respond and reveal that A included people without B’s awareness)

Visualizations

Visualizations: Overview
Goal is to allow one to quickly see how Mike’s network is connected and view structural holes
- Methodology- Spring/Wire explanation- View of entire world- Close-up views of network
danah boyd, Jeff Potter, Fernanda Viegas . Sociable Media, MIT Media Lab . Sunbelt . 17 February 2002
Visualizations: Methodology
Basic spring/node algorithm used to place nodes in optimal location
- annealing algorithms don’t work with 15,000 nodes
Colors are used to indicate the relationship to the person- based on which of Mike’s email address the person uses
- most common address used
danah boyd, Jeff Potter, Fernanda Viegas . Sociable Media, MIT Media Lab . Sunbelt . 17 February 2002
Visualizations: Spring/Node (1/2)
Basic spring algorithm used to place nodes
-Ties act as springs, pulling connected nodes closer together
-Nodes act like magnets and repel each other
danah boyd, Jeff Potter, Fernanda Viegas . Sociable Media, MIT Media Lab . Sunbelt . 17 February 2002
Visualizations: Spring/Node (2/2)
All nodes start out at random location, spring algorithm is run several hundred iterations
This (eventually) results in connected nodes being nearby and non-connected being far away

Social ImplicationsUsing one person’s email, we can
observe the social networks of hundreds of people - what are the implications of this?

Thoughts moving forwardMore detailed analysis
– Use visualizations to have ethnographic conversation with Mike
Extend to multiple users– Visual comparison valuable
Allow for interactivity– More detailed analysis of ego-centric graphs
Learn more from social network analysts
