2 Modes/styles of communication: Deductive & Inductive. So which one is the best?
Both of them. It really depends on timing.
For business communication, deductive is preferred (especially in emails!). Being deductive is when you go straight to the point, elaborating only if you need to. It is very economical.
How do you know if you are deductive? Before communicating, ask yourself, "what do i want the other person to know?". When you are on the receiving end, ask yourself,"What does the other person really want to know?"
For arts, writing novels, inductive is preferred because you get to be more descriptive. You can go to the moons and the stars across 9 planets before you come back to your point. Although bear in mind, we live in a society where Attention Deficit is a norm. So beware.
It is important to take note that each one of us have a default mode. So it is definitely going to take some time to practice and habitualize the other mode that we are not used to.
So good luck.
