Why do I have the lowest score?

I don’t know any official source, however there are some posts claiming that the score is based mostly on the amount of resources spent on tech. See for example:

I think score for tech at least is based on the amount of resources you spent on tech. As Delhi, this is always zero. I suspect society score is money spent on certain buildings: perhaps blacksmiths, universities and TCs? It’s very unclear to me though
