The Lasswell formula is a way to describe an act of communication that involves simple questions such as “who?” and “says what?” What Laswell has is a formula which is a statement that expresses a fundamental truth or principle. Jakobson had the model of communication. A model is an abstract way of representing the processes that occur in the world. Many of Jakobson’s elements answer the questions in Laswell’s formula such as “who?” would be the addresser and “says what?” would refer to the message. However, models tend to simplify and generalize things, which is true of the Laswell formula. It assumes that the communication is always based on influencing the receiver. However, there is what’s called phatic communication which is to express emotions not communicate information. The questions is does all communication have a desired effect?
