Researching think-tanks with social network analysis
Jordan Soukias Tchilingirian
1. An introduction to social network analysis • the basics• SNA and policy research
2. My application• What type of network study was this• How did I produce data• Strengths and weaknesses
Overview
Social Network Analysis
The basics
1. It is not the study of social media or
networking websites (though it is closely related to this!)
2. It is not a new method – roots in early 20th century soc sci, advances since the 1980s
3. It is not ‘data’
SNA is a distinct approach in the social sciences a relational approach
What is SNA?
‘Actors’ • Can be almost anything (people, animals,
organisations, families, computers, websites and so on)• Represented as ‘nodes’ or ‘vertices’ on graphs
Relations• Advice, likes, friendships, kinship ties, commerce,
sleeps with, dislikes, supports – any type of relationship you can think of!
• Represented as ‘edges’ or the lines/arrows on a graph
What is studied
Friends and family
SNA summer school
Department
Whole networks• Predefined sample of boundary e.g. all think-
tanks in Brazil, all staff of one organisation, all villages in a certain district and so on
Ego networks• Relations from the perspective of individuals • Sampling follows a similar logic to ‘normal’
science• Personal networks and social capital studies
Different types of networks
Where we do not know the actual relations between actors and infer from co-attendance
Network data: 2 mode networks
Where we know the relations between actorsYou can make 1 mode networks from two mode networks
Network data: 1 mode networks
Traditional• Positional analysis• Centrality• Network cohesion• Subgroups• Statistical analysis
NewDynamic and longitudinalBig data and social media
Analysis
• Interviews/questionnaires• Observations/ethnography • Secondary data e.g. diaries/biography,
documents, repositories
Data sources
• realist approaches define the boundary using the lived experience
of participants.
• nominalist approaches place an a priori boundary on the network which is theoretically useful
• positional approaches consider the membership of actors to certain groups of institutions.
• relational approaches are similar to snowball sampling
• event based approaches require the researcher to set a specific time (and possibly geographic) limit to the inclusion of actors.
Boundaries
Name Generators• the affective approach identifies relationships based
on a certain sentiment such as intimacy or personal importance to the ego
• the normative or role based approach identifies all ties connected to an ego through a particular culturally defined role, such as friend, kin, manager and so on
• the exchange approach focuses on the flow of resources (be they material, informational etc.)
• the interactive approach is based on the ego’s contact with alters within a specified time period.
Interview questions 1
Name interpreters • Questions about attributes
Questions about relations• Who knows who?
Also ‘social capital’ style questions
These are usually associated with ego/personal network designs

How I used social network analysis
My PhD…. British think-tanks and the production of policy
knowledge A social network analysis of policy intellectuals
The ‘decline’ of the public authoritative intellectual (Furedi, 2006) and the marginalisation of academics in public life and power (Halsey, 1992; Griffiths, 2009)…or the ‘transformation’ and the rise of new modes of public intellectualism (Baert, 2012; Bauman, 1989)
A case study of ‘knowledge brokers’ (Meyer, 2010; Osborne, 2004)• the transformation of expertise (Beck, 1992; Collins and
Evans, 2002)• the move to Mode 2 (social) science (Gibbons et al 1994;
Nowotny et al 2003)• corporate interests in policy making and expressions of the
elite power (Burris, 2008)• The journeys of evidence into policy (Smith, 2013)

My Approach
How do think-tank researchers create
knowledge?Sub question Chapter ApproachHow do organisational/ideological differences between think-tanks relate to the way think-tank research is conducted?
Chapter 4 Statistical analysis - Quadratic Assignment Procedure
What types of knowledge are valued by the think-tank community?
Chapter 5 Centrality measures and descriptive statistics
How do think-tank intellectuals discover knowledge?
Chapter 6 Qualitative analysis – focus on hidden networks and processes
How do think-tank intellectuals enrol different sources of knowledge into their intellectual interventions?
Chapter 7 Qualitative analysis – focus on the ‘politics’ of policy knowledge creation
…the networks which make an intellectual’s work ‘public’ and the controversies they are enrolled into (Eyal, 2010; 2013)
Positioning theory – an interest in intellectual teams and looser networks - both friendly and hostile - that give life to a debate (Baert, 2011, 2012)
Both focus on ‘products’ – the things intellectuals produce e.g. books, speeches, papers, lectures (also blogs, art, music….even tweets!) – has an ANT-ish flavour
Emergent networks: relationships which tend to be less formally structures and visible and which by their nature are interstitial as they draw disparate actors and institutions together (Kadushin, 1976, p. 770)
A sociology of intellectual interventions…
“An intellectual product locates the author or speaker within the intellectual field or within a broader socio-political or artistic arena whilst also situating other intellectuals, possibly depicting them as allies in a similar venture, predecessors of a similar orientation or alternatively as intellectual opponents”
Baert (2012, p312)
‘Interventions’
1. Inhabits several intersecting social worlds and satisfy
the informational requirements of each2. Plastic enough to adapt to meet the specific
needs/standards of the communities they cross3. But…can maintain a common identity across sites. 4. Have different meanings in different social worlds but
their structure is common enough to more than one world to make them recognisable
5. Key to developing and maintaining coherence across intersecting social worlds
(Star and Griesemer , 1989)

Quantitative element: Think-tanks that were engaged in contesting and producing knowledge for British social policy. This excluded organisations that:• specialised in environment, defence, international development,
macroeconomics• had a regional focus or an interest in a specific country within the United
Kingdom rather than national focus (e.g. North West or Wales only)• specifically defined themselves as a pressure group rather than a think-
tank or policy research institute• were not established as an organisation in 2005 or had ceased to operate
between 2005-2012• did not write specific policy reports, as opposed to other interventions
such as blogs. This did not mean that organisations with more essay like policy papers were excluded.
• This did not mean the think-tank could not produce policy reports on specific regions or for any of the devolved parliaments.
Boundary and sampling 1
Qualitative element - similar to quantitative• Approached senior and junior research staff
(or whoever holds these functions)• Aimed to have at least two interviewees from
one organisation (if the organisation is big enough)
Boundary and sampling 2
Mixed method SNA• Quantitative analysis of 1 and 2 mode networks• Qualitative analysis of personal networks
Ethics
Contribution?
Overview
Re analyse data to focus on• Network dynamics and longitudinal change• Collapsing authorship and advice networks – will
we find ‘super’ nodes?
Finer coding of quant to consider research themesWiden the sample to capture post 2005 think-tanks
Focus on personal networks from a quantitative and qualitative perspective
