Abstract

This paper considers diagnostic error in cooperative work as a contributing factor for a military ‘friendly fire’ incident. It emphasises aspects of the moment-to-moment sequential organisation of interaction, and turn design, to explore the significance for the error of a loss of intersubjectivity and joint understanding. The paper uses as data the cockpit video recording from a US Air Force aircraft that fired on a British armoured vehicle convoy in March 2003, in the early days of the Iraq War. The analytic approach is grounded in concerns of ethnomethodology (EM) and conversation analysis (CA) for uncovering the language, practices and processes of reasoning by which people accomplish social actions, particularly for conducting cooperative work. The paper highlights the impact for the participants’ perception, understanding and action of varying forms of participation, for example as speaker, addressed recipient, or as potential overhearing non-addressed recipient, and relative to participants’ involvement in the task at hand, and to their possibilities for accessing relevant phenomena (i.e. the vehicles and their visible features). Diagnosis in cooperative work demands that participants act relative to one another’s diverse perspectives and representations of the scene and its objects and events. Diagnosis requires participants to manage situations of ambiguity and uncertainty, and to resolve apparent conflicts of understanding and perceptual evidence. The paper examines the social character of diagnostic work by showing how processes of cooperation can be vulnerable and ultimately go wrong, particularly when multiple participants are physically distributed and interaction is mediated by communication technologies such as radio.

Notes

  1. For analysis of another aspect of the incident see McHoul (2007).

  2. As many researchers of human error have recently emphasised (e.g. Dekker 2006c), and as one reviewer of this paper also noted, the label or construct ‘error’ is applied and meaningful only after the event. At the time the pilots did not set out to make an error, and were not aware they were making an error. The pilots were performing their duties in what was to them a rational and routine manner.

  3. The three participants (the two pilots and the controller) work together towards the same overall battlefield goals, however here I will use the term ‘team’ to refer only to the two pilots. This is because the two pilots act jointly to perform tasks, complete goals, exchange information, and perceive and experience the battlefield, in ways not shared by the controller.

  4. See also related studies of teamwork and sense making in teams, for example Salas et al. (1995), Sarter and Woods (1995), Bowers et al. (2005), or Weick (1995).

  5. The HUD projects onto the external environment important flight information, for example on aircraft altitude and attitude (pitch, roll), so the pilot can spend less time looking down to the instrument panels.

  6. See also, for example, Luff and Heath (2002) on managing calls to the control room of an urban transport system, or Nevile (2004a) on airline pilots’ interaction with air traffic controllers.

  7. Evidence of controllers’ orientation to such a grid map appears in the data later when a different controller (not MH) calls the pilots, tragically just seconds too late and apparently unaware of the attack, to tell them of “friendly armor” in the area: “roger, Popov. (please) be advised that ah in the ah three one (.) two two: and three two (.) two two group box, (0.2) you have ah friendly armor (0.3) in the area, yellow, ah, (0.3) small armored tanks, ah jus’ be advised.”. The controller refers to the vehicles’ location by reference to their position on the grid map: “in the ah three one (.) two two: and three two (.) two two group box,”. The pilots immediately abort the attack and verbalise recognition of their error.

I began to analyse this data throughout September 2007 as a Visiting Scholar at the University of Tampere, Finland. I am grateful to Ilkka Arminen and the Research Institute for Social Sciences for the invitation, and for funding to make the visit possible. I have had the opportunity to develop my thinking, and to receive insightful feedback from many colleagues, when presenting on this data and analysis: in Finland at the universities of Helsinki, Jyväskylä, Oulu, and Tampere; in Denmark at the MOVIN Conversation Analysis network, at the University of Southern Denmark (Kolding), and as a paper at the conference ‘Language, Culture and Mind III’; in France at the Summer school I_DOCORA (Interaction: DOnnées, CORpus, Analyse) at the University of Lyon 2; and in Australia at the Discourse Analysis Group at the Australian National University, and at the University of Canberra. I thank especially Birte Asmuss, Pentti Haddington, Tiina Keisanen, Lorenza Mondada, Arja Piirainen-Marsh, Jakob Steensig, Sanna Vehviläinen, and Johannes Wagner. Thanks also to Birte Asmuss, Liisa Tainio, and Lorenza Mondada for informing my thinking and wording on specific points.
