Title: Fragmentation of identity through structural holes in email contacts


1
Fragmentation of identity through structural
holes in email contacts
  • danah boyd, Jeff Potter, Fernanda Viegas
  • (Sociable Media, MIT Media Lab)

2
Research Questions
  • How 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?

3
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

4
Managing Faceted Selves
  • Differentiated 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 retribution
  • Fragmented social network (e.g., work, clubs,
    family, )
  • Separate social circles provide for segmentation
    of presentation

5
Identity online
  • Confusion of context
  • Ease of moving between multiple contexts
  • Data aggregated across locations
  • Email address serves as context
  • Allows for privacy and faceted behavior

6
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

7
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

8
Ego-Centric Visualization
  • Visualization tool to observe social networks
    embedded in email
  • Focused on structure
  • Analyzed Mikes email habits
  • 5 years worth of complete data
  • Maintains multiple email addresses for different
    contexts
  • (Dis)advantages of using one persons behaviors

9
Introducing Mike
  • Social 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
  • Mikes primary social communities
  • Family, high school friends
  • Undergraduate friends
  • Gay men in/outside Boston, in NYC
  • Boston, Texas, California work colleagues

10
Mikes dataset
  • 80,941 messages
  • 1.03 average recipients per msg
  • 15,537 unique people
  • 7,250 people w/ 2,618 knowledge ties (excluding
    listservs)
  • 662,078 ties between all respondents (using only
    messages with
    million)
  • 226 trusted ties 23 reciprocal

11
Defining Connectivity
  • Knowledge 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 other
  • Trusted ties
  • If A sends a message to B and blind carbon copies
    (BCCs) D - A knows and trusts D
  • (D has the ability to respond and reveal that A
    included people without Bs awareness)

12
Visualizations

13
Visualizations Overview
  • Goal is to allow one to quickly see how Mikes
    network is connected and view structural holes
  • Methodology
  • Spring/Wire explanation
  • View of entire world
  • Close-up views of network

14
Visualizations Methodology
  • Basic spring/node algorithm used to place nodes
    in optimal location
  • - annealing algorithms dont work with 15,000
    nodes
  • Colors are used to indicate the relationship to
    the person
  • - based on which of Mikes email address the
    person uses
  • - most common address used

15
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

16
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

18
Visualization Entire World (1/2)
  • Color key for
  • all images

Social Implications
  • Using one persons email, we can observe the
    social networks of hundreds of people - what are
    the implications of this?

26
Thoughts moving forward
  • More 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
