The correct answer is high levels of individualism.
In societies where high levels of individualism is the norm and very common, conformity rates tend to decrease. The more autonomous and individualistic people are when it comes to norms, values, practices and self-expression the less conformity and collectivism there is. For instance, in an individualistic society, some individuals in society might not see marriage or monogamy as a suitable path for them compared to others who value marriage and monogamy.
