Of course the claim itself sounds very plausible, but I'd like to see the research, because your short summary makes me suspicious that it makes a correlation-is-not-causation kind of mistake. In other words, does the research support the claim that happiness is contagious or that it is clustered? Is there even a temporal aspect present in the analysis?

In the source I'm using, they claim to have checked for it via "mathematical analyses", but no further details are given. They do provide a reference to their their actual paper. This paper is also mentioned as having come to similar conclusions.

ETA: And here's the appendix they keep mentioning in the paper.

I can't remember where I saw the research either (it was recent though, maybe on Hacker News), but they did check casuation/temporal effects by following people over time and seeing that when one person became sad, people within a few social links of them were more likely to become sad, etc.
