It could mean "I'm lonely, so I think unlike everyone else." This doesn't make a lot of sense. Would people do it out of spite?
More likely "nobody thinks like me, so I am lonely."
The way it's phrased, I would guess they're after funding to spot idiosyncratic thinking to detect loneliness. Imagine if, based on the videos you like to watch articles you read, etc., they could detect that you were lonely, then target ads . . .
Makes sense to me actually: I wouldn't say it's even necessarily conscious, but the less you interact with others, the more you can become set in your own ways and create pathways to seeing your beliefs as truths.
I read one analysis of those who saved/hidden Jewish people during WWII. They tended to be socially isolated people, a bit outside of society. That is what allowed them to not fall to group think and to overcome fear. (The analysis was done by some Jewish institute).
That is why it is difficult to reenter socialization after long loneliness. There is gap between you and others, you feel lonely even if people are there. It took years to fully get back and for a while I thought I never will.
> Although it is unclear whether the observed idiosyncratic processing in lonely individuals is a cause or a result of loneliness, the associated lack of shared understanding may lead to challenges in achieving social connections.
