Running Scientists?

[Saxif]

I am struggling with the question on if I should run scientists or build cottages. I feel that without The Pyramids, scientists are only worth it for GPP.

I do however realise that a empire on 50% slider means that each scientists = a 6 gold tile for research output. However given grasslands can pay for themselves foodwise means you can run more cottages than scientists. Typically for me a good food city will have 6 specialists but that same city will only be hampered by happiness and unhealth regarding growing.

I know there is a post that goes into detail about this, can anyone link it? Or provide some guidance?

I think I monged out and put this in the wrong forum!
