• A political situation where government policy is influenced by the interests of a small minority, rather than that of the overwhelming majority.
• In politics, smaller groups at times can exert a disproportionate influence on government policy by virtue of being more organised than larger groups.
• Individuals in these smaller groups have more incentive to organise since the benefits they gain from a favourable policy are larger when they are part of a smaller group.
• In contrast, individuals in larger groups have lesser incentive to organise since the benefits they gain are smaller.
