Reading this ( good article, I found many topics that were almost ‘kwown’.
One topic is brand new to me, number 8: Over-splitting or over-lumping.

People have different styles of organizing thoughts when explaining complex situations. Some people, “splitters”, tend to pay more attention to how things are different. Other people, “lumpers”, tend to look for how things are alike. Perhaps this is a matter of temperament.
If the speaker and listener are on opposite sides of the splitter-lumper spectrum, the different mental styles can cause confusion or lack of understanding

Very interesting AND … how many things do we have to notice when we communicate?? Is our counterpart visual or auditive or …?? Is he D, I, S or C (check for the D.I.S.C. model)?? What’s his mind set?? Is he over-splitting or over-lumping?
