Parochial and Universal Cooperation in Intergroup Conflict

When Parochialism Hurts Out-group Competitors, Pro-social Individuals Extend Their Calculated Cooperation to the Out-group in Intergroup Conflict

Parochial Cooperation

The tendency to make self-costly contributions to one’s in-group

Examples parochial cooperation





Parochial Cooperation

The tendency to make self-costly contributions to one’s in-group

Can be, but does not have to be, harmful to the other party

Universal cooperation




Parochial cooperation is pervasive!

Parochial cooperation is pervasive!

Parochial cooperation

How can potentially negative parochial cooperation be shifted towards mutually beneficial universal cooperation?

What is the role of intergroup competition in the display of parochial cooperation?

What is the role of individuals’ predisposition towards cooperation?

Cooperation and social value orientation

Svo: ‘General preference for distribution of outcomes between oneself and interdependent others’ To prefer good outcomes for oneself (pro-self) or for both oneself and

others (pro-social)

Pro-socials compared to pro-selves: Value equality, reciprocity, fairness, cooperation More willing to self-sacrifice for collective (in social dilemmas) More generous in negotiation settings Expect others to cooperate more

Pro-socials are cooperators!

Pro-socials are cooperative!

But to whom? What is cooperation in an intergroupconflict?

Parochial? Universal?

Pro-socials’ cooperation dilemma in intergroup conflict

Cooperation with own group may hurt other group Cooperation with other group may hurt own group (or be

perceived as disloyal)

Research found pro-socials to be parochial cooperators: Sacrifice themselves for their own group, sometimes at the expense of the other group (Aaldering et al., 2013; Abbink et al., 2012; De Dreu, 2010; De Dreu et al., 2010)

What about decades of research suggesting that pro-socials care about collective welfare? (Au & Kwon, 2004; Balliet et al., 2009; Bogaert et al., 2008; Van Lange et al., 2007)

Possible solution?

Research showing pro-socials to be parochial and competitive did no include option for universal cooperation (Abbink et al., 2012; De Dreu, 2010)

Research showing pro-socials to be universal cooperation did not investigate an intergroup setting

We integrate these by investigating an cooperation in an intergroup setting where i) A mutually beneficial (universal) cooperation option is available ii) Competition is either present or absent

Nested Social Dilemma

Nested Social Dilemma

Three levels: Individual, group, collective

Game Instructions NSD

10 euro endowment. Investment in ingroup pool (A):

Each invested euro multiplied by two and then divided by four (equally among team members) Thus: 1 in, 0.5 return.

Investment in collective pool (B): Each invested euro multiplied by two and then divided by eight (equally among

members of both teams) Thus: 1 in, 0.25 return.

Personal pool: Euros kept to self.

Competitive NSD (NSD IPD) Each invested euro multiplied by two and then divided by four (equally among

team members) Thus: 1 in, 0.5 return plus subtracts 1 from out-group (0.25 per out-group member).

Hypotheses

1 Individuals will display more parochial than universal cooperation2ab. Pro-socials will invest more in the in-group and in the collective than pro-selves (De Pauw et al., 2014; Polzer, 2004)

When there is competition between the groups…..3a. Parochialism will be fueled: Even more investments in in- group, especially by pro-socials 3b. Parochialism will shift to universal cooperation: Especially

pro-socials are reluctant to harm out-group when there is a mutually beneficial alternative available

Hypotheses

When there is competition between the groups…

3a. Parochialism will be fueled: Even more investments in in- group by pro-socials

3b. Parochialism will shift to collective cooperation: Pro-socials reluctant to harm out-group

when there is an alternative available

Conclusion

Humans are parochial cooperators (more than universal) Pro-socials are parochial, but

They shift to universal cooperation under competition! They do not want to harm the other group if there is another

option to benefit the own group (collective benefit)

Intergroup competition is not necessary for parochial cooperation!

Study 2: Depletion

Hampers self-control

Universal cooperation should decrease if it is a calculated strategy Due to not being able to compute maximizing parochial outcomes Due to harm aversion

Study 2

Replicate study 1

If pro-socials are parochialists reluctant to harm out-group rather than intuitive universal cooperators:

Hypothesis 4: Collective investments in NSD IPD should decrease under cognitive load (compared to no cognitive load)

Results

When there is competition between the groups… H3. Parochialism will shift to collective cooperation: Pro- socials reluctant to harm out-group when there is an alternative

H4: Universal cooperation decreases under cognitive load: Not intuitive

Conclusion

Pro-socials are parochial, but not at all costs! When this self-sacrificing may hurt the other group and there is

an option to benefit both groups, pro-socials become universally cooperative (invest in the collective)

This is a calculated tendency: When their cognitive resources are depleted, pro-socials refrain

from collective cooperation and instead become more pro-self (NOT more parochial! Their inequality aversion and reluctance to harm the other group seems to be a primary mechanism)

But….

In NSD, maximal profit is equal on in-group and collective level

In NSD IPD, maximal profit is highest on collective level

Maybe, pro-socials are social welfare maximizers and choose the option that maximizes outcomes for both parties in general Which in the NSD could also be in-group investments; equal gain and smaller

risk

Pro-socials: Parochial or social welfare maximizers?

Experiment 3

Include outgroup hate pool IPDC: IPD MD plus collective option IPDC+: IPDC with maximal collective outcomes higher than

ingroup outcomes If pro-socials are social welfare maximizers, they should invest

more in the collective pool after playing this game compared to the IPDC

If pro-socials are parochial, they should not be affected by the increase in possible collective outcomes

H1: Overall, more investments in in-group (Pool A) than in collective (= parochialism):

Msubgroup = 3.02, SD = 2.25 vs Mcollective = 1.94, SD = 2.46, F [1, 166] = 7.25, p = .008, η2 = .08

Even stronger when investments ingroup include outgroup hate (combination of Pool A and B):



H2A Pro-socials invest more in in-group than pro-selves F [1, 161] = 5.38, p = .022, η2 = .032

H2B Pro-socials invest more in collective than pro-selves F [1, 161] = 8.57, p = .004, η2 = .05

No effect svo on outgroup hate (F [1,161] = 1.74, p = .19)

Interactions

No interaction Svo * Game on investments in-group (F (1, 161) = .128) or collective (F (1,161) = .72.

No interaction Svo* Game * depletion on investments in-group (F (1, 161) = .002) or collective (F (1, 161) = .290).

Conclusion

Pro-socials do not invest differently in the in-group depending on game structure and/or mental depletion

Pro-socials’ parochialism is real rather than a way to maximize social welfare

Role mental depletion unclear Increases cooperation in general? (Rand et al., 2012) Or

specifically parochial? (De Dreu et al., 2015) Decreases calculated cooperation? (Exp 2)

No reliable effects?

Discussion

Parochialism is default cooperation strategy but can harm intergroup relations

Intergroup competition decreases occurrence of parochial cooperation- especially among pro-socials

Inconsistency about nature of pro-socials seems (partially) solved: Depends on accessibility of collectively beneficial option and on presence of competition

Social welfare maximization does not explain pro-socials pro-sociality
