So far in BG3 Arcana, Religion, History and Investigation has come up I think.
These are very helpful tools, and Larian is using them a lot more than most DMs. I personally don't feel it's a dump stat, and unless I have a Wizard in the party I tend to put the crown on my character just to get 18 Int.
Honestly, I think Int is rolled just as much, if not more than Wisdom checks. But both are used very similarly to gain information.
