As a quant you constantly get told you don't communicate well. The real issue is that the fun frilly books written by business professionals or psychologists are too optimistic and too simple. People don't just fit into a few main groups. If people did, communication would be simple. We wouldn't have new books published every year on how to improve communication.
The main areas I see for defining communication are technical, social and cultural, and personality. Within each one of these groups there are many differences which cannot be simplified down into simple groups. Viewing people as individuals is a good start but more importantly, realize no one communicates well with everyone. It takes practice especially as you meet new people in areas outside of your comfort zone.
