A growing body of evidence supports the idea that intergroup contact can reduce discrimination. However, different types of contact – collaborative or adversarial – may have different effects. Based on experimental cricket leagues in Uttar Pradesh with participation from over 1,000 men from various castes, this article finds that only collaborative interaction across caste lines can successfully reduce caste divisions.
In the small town of Champaner, Gujarat, a group of villagers gathered to practice cricket in advance of an important match. This match was to be against their British rulers. Should they win, their taxes would be cancelled for three years. Should they lose, their taxes would be tripled. As they
Caste discrimination remains common in Uttar Pradesh – 37% of upper-castes openly admit to
A league of their own
With this segregation in mind, I recruited 1,261 men from all castes to participate in

Second, those assigned to the leagues were randomly assigned to teams of five – players then had from zero to four other-caste teammates (where caste here is either General, OBC, or SC/ST). Comparing post-league outcomes for those with more versus fewer other-caste teammates allows me to test whether collaborative contact reduces future caste discrimination. This can be considered a direct test of the key mechanism by which league participation might matter.
Third, teams were randomly assigned to opponents – players then also had variation in the number of other-castes faced as adversaries. Comparing post-league outcomes for those with more versus fewer other-caste opponents allows me to test whether cross-caste contact per se reduces caste divisions, or whether it must be
The study has three main findings:
- Participation in the leagues increased cross-caste friendships and teammate choice, and cross-caste trade.
- These effects are largely driven by exposure to other-castes as teammates.
- In contrast, exposure to other-caste opponents had either null or negative effects (with important qualifications).
Taken together, these findings suggest that cricket leagues can successfully reduce caste divisions in
Measuring caste divisions
I measured outcomes 1-3 weeks after the completion of each cricket league. To measure cross-caste social interaction, participants were asked to scroll through a list of the photos and full names of all other participants in their league, and select those they considered to be friends. In addition, they were asked to choose four others to be future teammates – and they had incentives to be honest, given that they were told that I would later randomly choose some participants to play a bonus match with their team of choice.
To complement these measures, I also designed a novel trading exercise to capture treatment effects on
Finding #1: Participation in the leagues increased cross-caste friendships and teammate choice, and cross-caste trade.
Figure 2. Effects of league participation
League participation increased cross-caste friendships by 45% of the control group average, to 3.6 (Figure 1, left panel).2 Similarly, the number of other-caste teammates chosen increased from 1.2 to 1.47, an increase of 23% (Figure 2, middle panel). Finally, while 49.1% of goods were traded with someone from a different caste in the control group, 55.4% were traded across caste by those that participated in the leagues – an increase of 13%. These results suggest that the leagues reduced caste divisions – but how exactly?
Finding #2: These effects are largely driven by exposure to other-castes as teammates.
I find the positive effects of league participation to be largely driven by those in mixed-caste teams – in particular, there is no significant difference in the number of other-caste friends and extent of cross-caste trade between the control group and those in homogeneous-caste teams (though those in homogeneous-caste teams do have significantly more other-caste friends than those in control).
Figure 3. Effects of collaborative cross-caste contact
Restricting to those assigned to play in the leagues, players with more other-caste teammates make more cross-caste friendships and choose more other-caste teammates (Figure 3, left and middle panel). More interestingly, neither of these results are driven solely by players becoming friends with their teammates – exposure to other-caste teammates leads to more other-caste connections even outside of the team itself, suggesting that collaborative contact shifts general tastes towards members of other castes. Consistent with this idea of shifting preferences, I find that collaborative contact reduces the in-group bias players show when voting on which other players should receive additional cricket training (though I find no evidence that collaborative contact affects cross-caste trust in a standard behavioural trust game).
Collaborative exposure also promotes economic exchange when gains from cross-caste trade (that is, the monetary bonus) exist (Figure 3, right panel). The effect is smaller and insignificant for those without the bonus – suggesting that collaborative contact is a complement to, but not a substitute for, cross-caste gains from trade.
Finding #3: In contrast, exposure to other-caste opponents had either null or negative effects (with important qualifications).
Figure 4. Effects of adversarial cross-caste contact
Where collaborative contact promotes cross-caste social interaction, adversarial contact destroys it (Figure 4, left panel) – players end up with fewer other-caste friends if they face more other-castes as opponents, and this result maintains even when I consider only friendships with non-opponents (that is, it is not just that players start to dislike those they play against).
In contrast, there is some evidence that adversarial contact increases cross-caste teammate choice (Figure 4, middle panel). Additional results suggest that this is because adversarial contact reduces statistical discrimination (because players get to see which other-caste players are good at cricket) while simultaneously increasing taste-based discrimination. In particular, the effect of adversarial contact on cross-caste teammate choice falls (significantly) to zero when I consider teammates chosen for a future match in which there are no stakes (that is, much weaker incentives to pick the best players).
Finally, while the effect of adversarial contact on cross-caste trade (for those with the bonus) is negative, it is far from significant. Taken together, these results suggest that it is not cross-caste contact per se that reduces caste divisions, but rather contact that is collaborative.
Two limitations of this study (at least) provide avenues for future work. First, all outcome measures are relatively short-term. Whether effects persist is an open (and important) question, and
Second, the individual-level randomisation prevents the estimation of general equilibrium effects. To the extent that important caste-based norms operate at the village-level, these effects may be the most policy-relevant. Future work could address this concern by scaling up the intervention, with randomisation at the village-level.
Policy implications and discussion
This experiment complements a growing body of evidence supporting the “contact hypothesis” – the idea that intergroup contact can reduce prejudice (Allport 1954, Rao 2014, Scacco and Warren 2018, Paluck et al. 2017). In this case, it seems that integration per se need not be effective (and may even be detrimental). Rather collaborative integration is what reduces intergroup divisions.
These results imply that integrated cricket leagues may provide a natural and effective means of reducing caste division among young men in India. More broadly, they suggest that integrative programmes
