Do Research Sites Stack?

[Mauer]

If I have a dome whose radius covers two of the new Research Sites that give a research 20% boost, do my research buildings in the dome get both? If so, is it additive of multiplicative (+40% or +48%)?
The research building only shows the total.

Anyone know? I was just about to ask this myself, when this thread showed up. Anyone know? How about the vista?

Still no idea, I imagine the vista would be easier to test as you don't have so many variables affecting the total comfort than you would have with research output, but I haven't found a place with two vistas close enough.

Had a site with two vistas which - when placing the dome that covered both - got an additive bonus, I'm pretty sure. Imagine it'd be the same for the Research sites. Doesn't the info panel which pops up on the right when placing a dome give an indication?

When placing the dome it only states that it has a Research Site nearby, regardless of how many it covers.

FYI, someone in the Steam forums tested it and apparently the bonuses do stack.
