Here is a table with a few pointers.
I'm still trying to learn CE so there are multiple pointers on some items.
Can confirm that it works.

Notes
STAR, CULT, LOVE, FOOD > In order to do research that goes beyond the current limit (This is level based and you can only use 50 at the beginning of the game),
Go to Menu > Industry > Research > Activate the hotkey corresponding to the item you need > Purchase the research > exit menu.
After exiting the menu the values of all those four items will reset to the max.
