Check the "About" page. It's a self-published, non-peer-reviewed paper, written by a distinguished academic researcher.

The About page doesn’t say anything about whether it was peer-reviewed or not (nor supplies any evidence that the author is “distinguished”). Maybe it was peer-reviewed and rejected, hence why a “distinguished” researcher would resort to self publishing? It seems to contradict other much larger-scale studies like https://www.nature.com/articles/s41562-017-0277-0

Oh it's Matthew Killingsworth, who was the first author of the one paper [1] about happiness I actually read!
