The awareness of the knowledge of another self, and vice-versa may allow to detect such biases.
Imagine a learning system where you can tag each word and concept to express your understanding from low to high.
Learning through an interface builds a unique knowledge map for each individual in a semantic database.
Then, when individuals discuss certain matters, a speech-to-text interface inputs the words.
Each individual has like its smartphone connecting with others and comparing the knowledge trees to alarm in case of a possible cognitive dissonance when the called concepts are not similarly understood by each individual.
The software can then suggest concepts that can "fill the gap", or different approaches, meanings, to express the "conflictual" concept.
I depict a day-to-day scenario, but such software can also scan mails, chats, news...
So basically, comparing two individuals knowledges.
With an education system using such tool and scanning every word and concept written and read by its students...
The awareness and practial uses of such understanding of one's knowledge may open new ways to communicate and exchange knowledge as trackable data, ideas and concepts will have coordinates in space, time, and in the knowledge tree.
The ability to track and map all this data flows, to computerize so that we can manipulate, simulate, compare, program not only our knowledge, but also our flows of knowledge.
I digressed a bit, but i think such concept may have many other applications.
