Thats what I meant by multiplicative effectHmm, Carl says specialists "boost" adjacencies a couple times and Ed says they "help" adjacencies at one point, but neither of them described how they do so mechanically.
I expect it will be additive and not multiplicative as you described above. For example, if you have a Quarter with two late-exploration age buildings with 5 base yield and 4 adjacency yield, with a multiplicative effect from specialists you'd only need two to reach 40 yield ((8 x 2 x 2) + 10 = 42) whereas if additive, it would require 4 specialists (8 + 8 + 8 + 8 + 10 = 42) which seems more in line with what we've seen in the tech tree.
Edit: For completeness' sake, here is the section from the dev diary (sadly, quite vague as well):
Edit 2: More digging: at 1:25:04 of the exploration stream, Carl places a specialist on a bazaar/market quarter, adding 1.5 gold, 2 sci, and 2 culture to the tile. Other potential specialist spots just gave 2 sci and 2 culture, as all the rest of the buildings in the city were from the antiquity age and thus no adjacencies. The bazaar had an adjacency of 3 (was placed at 47:24) so specialists have either a 1.5x modifier on adjacencies, or add a half yield per adjacency. Of course there are policies and other effects that could modify this later as well.
(1+# of Specialists)*Base Adjacency= Total adjacency yields
Now you could also have that as each specialist gives +100% to adjacency… but a flat % of adjacency per specialist rather than a flat amount per specialist.
** it could instead be (1+specialists/2) aka +50% per specialist as well, or some other number used… each specialist adding one full adjacency would be simplest, but might be too easy.
just saw above so looks like it is 50% per specialist…at least at one point
(and an additional +4)
so…2 base 5, adj 4 buildings
base=10
adj=8
each specialist=4(cult+sci)+4(adj boost)=8
so 3 specialists gives 24
for a total of 42
you can reach 2 specialists per tile with the education tech
reaching 3 is probably not too hard.
It maybe harder to get that ~8 total adjacency in 5 separate tiles
