If you hold the mouse over the various sim characteristics in the Likes/dislikes panel,, it will tell you what traits (and it's traits, more than other areas that will impact compatability) affect compatability. In my save for the Event, All members of the family have the Adventurous trait, and also like sims that have similar traits (I want to say Spirited and Nature Lover, but double check) because I wanted a very close knit family for that save.
If I'd wanted to say make the youngest isolated, I could have given her the Creative trait, and had all the rest of the family dislike Artsty sims.
True. I will look at the traits that aren't compatible. Thank you! But I honestly thought that dislikes/likes would do it.
