What if Kim had a traumatic childhood, and had common issues with this like abandonment anxiety and poor boundaries? She could not see how her group could make decisions without her and her negative childhood experiences are projected onto the situation causing anxiety.
What if Kim was a healthy adult? She would maybe not have negative experiences projected onto the scenario and perhaps could easily switch to making plans by herself without her group with healthy boundaries.
What if the group was traumatized as well? The group would probably treat Kim like they were forced to treat their parents: giving Kim their full focus and emotional libido in order to avoid a fallout. This group would certainly project their insecurity onto Kim and assume her devastation.
What if the group was healthy and had healthy boundaries? The group would, perhaps, know they could not assume how the other individual would react and video call her to see if she was OK and negotiate on-call. (Any assumption of Kim's response is just projection - and studies show that the older and more experienced with social situations a person becomes the more they know they can't accurately assume how a person reacts) Positive feelings are projected onto the situation and no one projects negative experiences.
"Low social intelligence" isn't considered by most people, but childhood trauma is - and childhood trauma would clearly affect what happens. Childhood trauma causes negative affective emotions in social situations, good-enough parents cause positive affect in social situations - *NOT* social intelligence pseudoscience.
