Is that intended as a recommendation of a scientific source about long-term trends cross-culturally? I got a big volume of the collected "future history" stories by Robert Heinlein out of the library a year ago, and I was disappointed by how poorly those stories have aged.

I like to read real science based on verifiable history to puzzle out social trends. I can recommend a source
