Previous sections have identified ways in which people from different cultures can live together peacefully, but in practice there are many examples of discord. The following sub-sections identify different causes of conflict:
- People have a natural tendency to form groups which often exclude people from other groups, engendering mutual suspicion and sometimes outright hostility (126.96.36.199).
- This potential for hostility can be consciously exploited by people seeking power (188.8.131.52).
- Immigrants may look different and might have unfamiliar customs. Some people resent the resulting change in the character of their neighbourhood (184.108.40.206).
