It is our experience that it is much quicker to figure out where people are on the Interpersonal Circumplex in a given situation than to determine their MBTI, so for short term interactions we prefer Dr. Leary's system and for longer term relationships we would then attempt to establish the MBTI or socionic type. Either way, typology is very useful for figuring out how various types will react to a given communication. In general, a communication is more powerfully affecting if it is grounded in experiential details. Describing the sights, sounds, smells, and other sensations of life brings a feeling of immediacy to any communication. Except for specific purposes where it is useful to be disassociative and abstract, you should include multi-sensory details in all of your signals; don't just provide a recipe, give your audience the warm yeasty smell of your freshly baked bread.
The point of your signal is to affect reaction in your audience, to insert your experiences into their consciousness so that your desires then become theirs. When you are engaged in ritual acts your art and output are not simply matters of self expression, they are more than representations; they precipitate action. Knowing who your audience is and what they want is the first step toward getting that audience to take the action you want them to take. In this vein, let's examine the example of the bread store that just went out of business near Edward's home.
As the bread store was already a food store, they should have had more options for consuming their products, such as tables and drinks. They lost business when they stopped making pizza buns, a cheap option that made it possible for people who were reticent to buy their premium products to start smaller and, over time, grow attached to their brand and product line. They could have had daily specials and surprises to encourage people to come in and check out the store stock on days they normally wouldn't have gone inside. A board or placard advertising specials on the street would also have helped transmit signals to those nearby that there were innovative products inside for special prices. These kinds of ideas can be abstracted into any system or pattern, injecting flexible behavior where entropy might otherwise stifle growth.
