Are communicability and verifiability the only reasons to prohibit other true results? In order to publish a research paper in a particular domain, or the domain itself must satisfy the above two requirements: Communicable to and verifiable by other people. Isn't it?

In this context, I got a doubt that the content of research papers are limited by objectivity and results that cannot be either uncommunicable or unverifiable are considered off topic and are never encouraged in the either academic or the scientific community. 

Isn't it limiting the scientific development that can reach such truths also?
First you need to remember that science is not the only form of research. Second, subjective results come in all sorts of flavors. If I ask one person person if they like A better than B, that is a subjective result. If I ask 1000 people, and do statistics, is that still a successful subjective result? Someone else could ask a new group of subjects the same question and verify my results.

Now consider an objective measure of a one time event (e.g., the amount of snow that fell during a storm). No one can verify the measurement, but it is still objective.
