OK, Sorry to not reply sooner. What i want if that's ok , For you guys to check what i'm doing wrong with my science.
I'm kind of used to arguing against Monarchy but it's 1800AD and you are still in Despotism. Get out of this government now! This is your major hurdle to a faster tech rate. To demonstrate this I decided to play a few turns without changing everything that I would normally do...
First I saw that you could get Democracy so I traded for it...
You've generally got your empire well roaded so the commerce will increase under this government. If this wasn't available I would choose Republic. (You will need to be wary of War Weariness in these goverenments so make any wars short, sweet and decisive.)
Next I revolted. I was lucky; this could have been twice as many turns but even then you will soon recoup that time.
I then played out the four turns doing minimal stuff. I found a number of workers asleep in towns so I woke them and got them helping on a strategic rail network.
When the four turns was up, I then disbanded pretty much every sword, pike, and spear that you had to cut down on the unit costs. Whilst doing this any unit builds were switched to markets. Ther is no difference now in the negative gpt and your research time has been halved. Before and after F1 screens:
Personally I would not abuse the negative gpt on Chieftain and reduce my research to about 60%. This will still get electricity in fewer turns than when you were in Despotism.
There is a town that was building JSB. Whilst it is not the best place for a Forbidden Palace, it is far enough away from Washington to give you a second core and increase your commerce/reduce corruption dramatically. It will be ready in 7(?) turns. There are a number of markets that will soon be ready due to the shield boost from disbanding so many units and this will also increase commerce if you do not have your research at 100%. They will also kick off WLTKD (we love the king days) in many towns, thus reducing corruption even further.
You still have a massive military. I would take over the Zulu lands as this will be around you FP town and so form part of your second core and then lose some more obsolete units. Do not build any more military units, except for a few cannons perhaps. Build Libs and Unis in your core towns, Flood those plains to increase your population and notice the difference in your research power.
There is much more that I would do if it were my game but I didn't want to hide the effect of a change in government. #1 would be more workers!!!!
1808AD Save attached at the end of this post. Hope this helps a bit.
And i have a question, Does negative gold slow down science research? OK Thanks.
No, but you will lose units/buildings every turn above Chieftain.
