Contact, trust and social capital in Northern Ireland: a qualitative study of three mixed communities

In a recent paper, Robert Putnam (2007) challenges the contact hypothesis by arguing that ethnic diversity causes people to ‘hunker down’ and essentially withdraw themselves from society. Drawing on
qualitative data collected from three mixed communities in Northern Ireland, this paper explores the extent and quality of contact experienced by Protestants and Catholics in their everyday lives. Themes emerging from our data are generally consistent with the contact hypothesis. There is also some support for Putnam’s theory that mixed environments can induce ‘hunkering down’ and that inter-group trust may be compromised. However, our data challenge Putnam’s argument that these responses are a consequence of ‘anomie’ or ‘social malaise’. Rather, we find that withdrawal from social activity in the neighbourhoods we observed was a calculated response at times of threat, often aimed at protecting existent positive inter-ethnic relations.

What now for the contact hypothesis? Towards a new research agenda

This article begins with a review of recent research on the Contact Hypothesis. It will be shown that the literature in this area has become essentially closed and self-referential where the core political and theoretical premises that underpin the Hypothesis have been taken for granted and the debates have therefore become restricted simply to how best to measure the influence of inter-group contact. One of the key reasons for this is the lack of critical engagement with the Contact Hypothesis from those of a more structuralist and/or ‘radical’ perspective. This may be because the individualistic focus of the Hypothesis is seen from such a perspective as largely irrelevant to addressing racial and ethnic divisions and/or because it may be felt that to engage with the concept is to give it undue legitimacy. It will be argued in this article, however, that the wholesale dismissal of the Contact Hypothesis is a little premature. Just as recent research on racial and ethnic divisions has drawn attention to the way in which such divisions exist at a number of layers within the social formation – from the structural, political and ideological through to the sub-cultural, interactional and biographical – so must any initiatives aimed at addressing these divisions be similarly ‘multi-layered’ in their approach. However, it will be argued that for research to help inform specific strategies at the interactional level, there needs to be a significant change in the way that inter-group contact, and the Contact Hypothesis more generally, is studied. The article will ‘model out’ one potentially fruitful way in which such research can develop through the use of an ethnographic case study involving a cross-community scheme arranged for Protestant and Catholic children in Northern Ireland.

Langerhans cells protect from allergic contact dermatitis in mice by tolerizing CD8+ T cells and activating Foxp3+ regulatory T cells

Allergic contact dermatitis is the most frequent occupational disease in industrialized countries. It is caused by CD8(+) T cell-mediated contact hypersensitivity (CHS) reactions triggered at the site of contact by a variety of chemicals, also known as weak haptens, present in fragrances, dyes, metals, preservatives, and drugs. Despite the myriad of potentially allergenic substances that can penetrate the skin, sensitization is relatively rare and immune tolerance to the substance is often induced by as yet poorly understood mechanisms. Here we show, using the innocuous chemical 2,4-dinitrothiocyanobenzene (DNTB), that cutaneous immune tolerance in mice critically depends on epidermal Langerhans cells (LCs), which capture DNTB and migrate to lymph nodes for direct presentation to CD8(+) T cells. Depletion and adoptive transfer experiments revealed that LCs conferred protection from development of CHS by a mechanism involving both anergy and deletion of allergen-specific CD8(+) T cells and activation of a population of T cells identified as ICOS(+)CD4(+)Foxp3(+) Tregs. Our findings highlight the critical role of LCs in tolerance induction in mice to the prototype innocuous hapten DNTB and suggest that strategies targeting LCs might be valuable for prevention of cutaneous allergy.

Behavioural consequences of imagining intergroup contact with stigmatized outgroups

We investigated whether imagining contact with an outgroup member would change intergroup behaviour. Participants who had imagined a positive interaction with an outgroup member or an unspecified stranger were told that they were about to take part in a discussion task with an outgroup member. They were taken to a room and asked to set out two chairs ready for the discussion while the experimenter left, ostensibly to find the other participant. The distance between the two chairs was then measured. Undergraduate students who imagined talking to an obese individual (Experiment 1) or a Muslim individual (Experiment 2) placed the chairs significantly closer than those in the control condition. They also reported more positive feelings and beliefs regarding Muslims. These findings highlight an important practical application of imagined contact: preparing people for successful face-to-face contact.

From imagery to intention: A dual route model of imagined contact effects

Imagined intergroup contact (Crisp & R. Turner, 2009) is a new indirect contact strategy for promoting tolerance and more positive intergroup relations. In this chapter, we review existing research on imagined contact and propose two routes-cognitive and affective-through which it can exert a positive influence on contact-related attitudes and intentions. We first review research that has established the beneficial impacts of imagined contact on intergroup attitudes via reduced intergroup anxiety, supporting its efficacy as an intervention where there exists little or no opportunity for direct contact. We then review more recent research showing that imagined contact not only improves attitudes, but can also enhance intentions to engage in future contact. These studies suggest that contact imagery provides a behavioural script that forms the cognitive basis for subsequent judgements about future contact intentions. Collectively, the findings from this research programme support the idea that imagined contact can complement more direct forms of contact-providing a way of initially encouraging an interest in engaging positively with outgroups before introducing face-to-face encounters. We discuss the implications of these findings for future theory and research, and how they can inform prejudice-reduction interventions seeking to capitalise on the beneficial effects of mental imagery.
