Displays of humility are most characteristic of those who value

Collectivism is the correct answer.

Displays of polite humility is very common among those who value collectivism. In a collectivist culture, such as Brazil, Japan and India, the emphasis is on the needs and goals of the group as a whole and not on the individual alone. Differently from what is usually seen in individualistic cultures, people from collectivist cultures are very supportive, humble, and afraid of being rejected.
