I remember one time there were two articles on the front page of HN. One says "If you want to be more productive, be more happy", then you scroll down and you find "If you want to be more productive, be more depressed".

Take a look at this article for example https://www.theguardian.com/news/2018/aug/27/religion-why-is...

Determining if religion is declining or rising is more complex than just making a poll.
