Social Science Bites - Salma Mousa on Contact Theory (and Football)

There’s an intuitive attraction to the idea that if we could just spend some quality time with someone from another group, we’d both come to appreciate, and maybe even like, the other person and perhaps even their group. Enormously simplified, that’s the basis of contact theory, which Gordon Allport posited in the 1950s as the United States grappled with desegregating its public schools.

If differing groups could be brought together cooperatively – not competitively – in a manner endorsed by both groups and where each side met on an equal footing, perhaps we could, as Salma Mousa puts it in this Social Science Bites podcast, “unlock tolerance on both sides and reduce prejudice.”

Mousa, currently a postdoctoral research fellow at Stanford University’s Department of Political Science, tells interviewer David Edmonds that since Allport’s heyday, “We have [had] a lot of studies about contact, but we need experimental tests of contact.” She’s been working to address that need, sometimes using the football pitch as a field site, with work that’s caught both the public and the scientific imagination.

One experiment she was part of examined the incidence of hate crimes once Mohamed “Mo” Salah, the talented Egyptian soccer star, signed with Liverpool Football Club. The results were heartening; Merseyside, where the club is located, experienced a 16 percent drop in hate crimes while anti-Muslim tweets from Liverpool’s fans dropped to half the number compared to fans of other Premier League clubs.

In this interview, Mousa details another experiment involving football and otherness, albeit an experiment made under harsher conditions: “We set out to learn if positive, social contact across social lines can reduce prejudice, can build friendships, can overall improve relationships between groups even in postwar settings, like Iraq.”

The experiment was conducted along the faultlines of northern Iraq where there’s a Kurdish enclave. Working with a Christian community organization which was helping Christians and Muslims displaced by ISIS, the researchers recruited Christian amateur soccer players for a football league. They then added three or four players to each team, randomly adding either all Muslims or all Christians as the newcomers, and tracked player attitudes and actions on the field and off for a half year after the season ended.

Amid some “really profound friendships” that formed, survey results and observed behavior showed that the Christian players came to be much more accepting and welcoming of their Muslim teammates. But that warming did not make the leap to their attitudes towards Muslims in general, suggesting some underlying prejudices remained in place.

While her promising findings nonetheless were not the “home run” people of good will would have liked, the research earned the cover of the journal Science, and left Mousa feeling optimistic about further possibilities of contact theory. Given the difficult context of postwar Iraq and subjects scarred by their flight from ISIS, “to find some evidence that these guys actually became friends and we changed something in these communities, I think is positive, especially given that these communities are persecuted and highly distrustful.”

Fostering tolerance and eroding prejudice, especially in the Middle East, matters personally to Mousa, an Egyptian-Canadian who grew up in Saudi Arabia, the United Arab Emirates, Qatar and Canada. She’s focused on helping “fix” the region’s ethnic and religious divides: “I think of myself as an engineer but with a social science background.”

Mousa has held fellowships at the U.S. Institute of Peace, Stanford’s Immigration Policy Lab, the Freeman Spogli Institute, the Stanford Center for International Conflict and Negotiation, the McCoy Center for Ethics in Society, and the Stanford Center on Philanthropy and Civil Society. Her work has been supported by the Abdul Latif Jameel Poverty Action Lab, the Innovations for Poverty Action Lab, the King Center on Global Development, the Institute for Research in the Social Sciences, the Program on Governance and Local Development, and the Abbasi Program in Islamic Studies.

Unexpected Elements - Osiris Rex stows asteroid material

Last week NASA’s Osiris-Rex mission successfully touched down on asteroid Bennu’s crumbly surface. But the spacecraft collected so much material that the canister wouldn’t close. NASA systems engineer Estelle Church tells Roland Pease how she and the team back on Earth performed clever manoeuvres to remotely successfully shut the lid.

As winter draws on in the North, and people spend more time indoors, there’s considerable debate about the conditions in which SARS-Cov2 is more likely to spread. Princeton University’s Dylan Morris has just published research exploring the coronavirus’s survival in different humidities and temperatures.

Indian agriculture in some areas uses vast amounts of water. Dr Vimal Mishra of the Indian Institute of Technology in Gandhinagar has discovered that this irrigation, plus very high temperatures, is causing not just extreme discomfort amongst the population but also more deaths.

In the 1930s serious dust storms over several years ruined crops and lives over a huge part of Midwest America. The dustbowl conditions were made famous by the folk songs of Woodie Guthrie and in John Steinbeck’s novel Grapes of Wrath. Now a study in Geophysical Research Letters suggests that levels of dust have doubled in the past twenty years. Roland Pease asks researchers and farmers if they think the dust bowl is returning.

We’ve probably all got a friend who sings along wildly out of tune - or maybe you are that person. But why are some of us apparently tone deaf, while others can hold a melody? Can you train yourself to sing in tune, or is it mostly down to raw talent?

These musical questions, from CrowdScience listeners Jenny and Anastasia, certainly struck a chord with us. Anastasia loves to sing but her friends tell her she’s off-key - or that “a bear trod on her ear,” as they say in her native Russia. Is it possible for her to improve her singing voice, and what are the best ways of going about it?

Both musicians and scientists help us tackle these questions, and explain what’s going on in our ears, brains and throats when we try to sing the right notes. We learn about congenital amusia, a condition which makes it almost impossible to tell if you’re in tune or not, and attempt to tease out the relative influence of our genes and our environment when it comes to musical ability.

Unexpected Elements - Nasa probe Osiris Rex lands on asteroid

Science in Action talks to Nasa researcher Hannah Kaplan who is part of the team for the space agency’s sampling mission to the asteroid Bennu. Mission scientists were overjoyed this week when the probe Osiris Rex momentarily touched the asteroid and sucked up some of the sand and grit on its surface.

What might we learn when the sample is returned to Earth in three years' time? There is some not-such-good news about a theory about immunity to the pandemic coronavirus, and medical researchers in the UK announce the world’s first study that will deliberately infect volunteers with the novel coronavirus. The so-called challenge study is planned to begin in London in January. The purpose is to speed up the quest for effective Covid-19 vaccines but will it be safe for the participants? And there’s a new green chemistry breakthrough for tackling the world’s plastic waste crisis.

And All living things are related to each other, from elephants to algae, e-coli to humans like us. Within our cells we hold genetic information in the form of DNA or RNA. But despite viruses sharing these molecules, many scientists don't consider them to be 'life'. Viruses cannot reproduce on their own, but some can insert their DNA into a host to pass genes sideways through the branching tree of life. As a result, viruses’ relationship with life is.... complex.

Two of our listeners had viruses on the mind, so they sent in the same question to CrowdScience. Senan from Singapore and Melvin from South Africa want to know how viruses began to see if this can tell us whether they shared a common ancestor with humans.

To dig into this complexity Marnie Chesterton speaks with an expert on Koala genetics – Dr Rachael Tarlinton. Koalas are in the middle of tackling a retroviruses, a type of virus that plants DNA into our cells as a reproduction strategy. Her research could reveal why humans life has so much viral DNA within our genomes.

Marnie speaks with a computational biologist Professor Gustavo Caetano-Anolles, who has found a new way to trace the family tree for billions of years using proteins common to all life on earth, and speaks with Professor Chantal Abergel who paints a picture of how viruses went from being the losers of evolution, to being highly successful parasites of cells.
