One of my villagers, Papu, has no "likes or dislikes" but each time I put him at the research table, he goes fishing! If I put him at the crops, he goes fixing a hut or searching, etc... It's not very important, just a little bit irritating
An other one, just arrived by the waterfall, with no "likes or dislikes too" just some parenting skills, enjoys the pond, exercises, relaxes at the beach etc, each time I put him to do something. So I appeal to him as soon as a child is a little bit lonely and now he is the teacher of the tribe but I don’t know if he becomes an "Esteemed Elder" one day.
In VV1, a girl liked running. Nice, but she banged every time into some thing and when she harvested the crops or the berries, only 2 out of 3 baskets went in the bin. It was very funny!!
