Granularity (communication science)

from Wikipedia, the free encyclopedia

The communication science term of granularity ( Latin - granum : "grain, core") describes the qualitative measure of the "accuracy of fit" of information from the perspective of the recipient .

Containment

The question of whether information is granular from a pragmatic point of view is assessed according to four criteria:

  • The validity makes a statement about whether an information has a validity , ie is true in the colloquial sense or at least truthful. Sitting in a wintery, snow-covered, northern Norwegian coniferous forest, the message, “It's warm!” Seems more like a desperate call to persevere. It is not true.
  • The reliability indicates whether information a certain selectivity has, that is, whether it corresponds to a minimum standard of accuracy or trustworthiness comprehensible. The only fever patient who happened to be spoken to among a large group of healthy people in a cold room, who replied "It's warm!" To the question about the temperature in this room , falls within the empirical context of the people present (who admittedly the situation completely different judge) clearly out of the ordinary.
  • The relevance in this context describes the importance , ie whether information from the receiver at best sought was, or at least he expected to be, but at least at all in his associative space sense appears. In the operations room of the NASA ground control station in Houston / Texas five minutes before the start of a space shuttle last runaway start procedure checklists is the finding of the Deputy IT technician, "It's warm!" , Probably because of their utter Deplaziertheit not be perceived.
  • The Impact finally is contextually-perceived difference of information content before and after the transfer. The breathless in the back of the cave dwelling tumbling Neanderthals that his lingering there extended family with the statement, "warm it is!" , Announcing the long-awaited and completely surprising in broken early spring, has "more" informed than the young cook in the kitchen a restaurant that bores its sous chef with the same statement about the sauce he has made.

Demarcation

Objectivity, on the other hand, is not a mandatory measure of granularity, since, for example, the prejudiced recipient only wants to be confirmed in terms of his or her subjective reservations in the course of receiving information and can still be satisfied with information to the greatest possible extent.
