> Lonelier individuals were also more likely to use unusual language when describing well-known celebrities and to describe them in ways that were not typical for their group.

How is that surprising? If they are lonely, they are not part of the group and intergroup communication (including shared values, opinions, gossip etc).

The text fails to define "unusual" in a meaningful way other than "not part of the majority". It's like saying "we found that the minority tends to vote differently than the majority".
