Society has a lot more techs which end up being pretty minor. It makes sense you progress through that research easier. Keep in mind engineering tends to contain the most powerful and useful techs.
there should be a policy add one type research output and lower other two
Where do you get all this Society science from? If it's anything I swim in it's Physics science as almost all system based science I encounter are Physics. Engineering always lags behind. In my current game I got 600 Physics, 380 Society and 320 Engineering.
Whyis having more society research a problem?
Perhaps a simple "fix" would do the trick? Planetary decisions that transform research of one type into another for all 3 major types, at an efficiency loss, how does that sound? It would at least be less clunky than policy-level settings due to being able to dodge the 10-year cooldown, and would allow you to specialize tech worlds in a particular type of tech. Or would this be too OP?
Also keep in mind that scanning debris helps recuperate some of the ground physics and engineering research loses to society research.
I'm pretty sure it's mostly an OCD problem. Same with people having fits about "clean borders" in CK2 and EU4.
Don't confuse OCD for min-max. As I would hate to waste most of my society planet deposits by not utilizing them just because of this slant and forcing me to abandon intelligent due to 10% society bonus.
Why is this forcing you to drop Intelligent? That doesn't make any sense. You just... keep using Society research and do repeatables? How is it a waste? It seems like a complete OCD thing.
And I’ve stated before. Ultimately, I think his justification for the desired change is strange.
But I agree with the option in principle. There was times in previous builds where I strived to specialize my research, either for RP reason, or to reach a goal tech more reliably.
This notion of more society reduced my gain is an absurd justification as far as I’m concerned. But the issue of being able to focus resources makes sense to me.
