How do you gain research?
I have several things in the shop that require research to purchase and I have a counter under my finances for it, but I haven't found a way to increase it. How do I gain research?
Edit: I seem to have received one research, but I'm not sure what caused it. Does it accrue over time?
Thanks to murgatroid99 for explaining it to me in chat, you receive research by clicking work while having no paperwork to do.
