Hey! I had a question about using not in logic - getting myself confused with De Morgan's logic.
When building a cohort, I want to exclude anyone in who is in any of the cohorts A or B or C.
Which is the right logic to use:
(User not in Cohort A Cohort B Cohort C) - I get 1,688 users returned.
(User not in Cohort A) and (User not in Cohort B) and (User not in Cohort C) - I get 435 users returned.
I suspect it's the latter which is correct but wanted to see if anyone else has any ideas...
