The effect ELIZA is a tendency natural to associate with the words one or more significances on the basis of former experiment. As example, the symbol " +" , in oneself, nothing in particular has that it makes it more suitable than another symbol to mean operation of addition. Quite naturally, and this by practice, one associates it however with the addition. In a computer programming language, one benefits thus from effect ELIZA by using the symbol " +" or the term more to mean addition rather than another operation.

This effect finds its origin in the Chatterbot of the even name. This computer program simulates a conversation while reformulating in questions of information which its interlocutor provides him, and in posing to him. One could have the following situation:

- Human: I was always very accessory with my sister. - ELIZA: Speak me about your family.

On the basis of his experiment, the interlocutor thus will consider that ELIZA finds this conversation interesting and wishes to know some more in connection with its family. Actually, the program does nothing but follow one protocol: he recognizes the term sister and answers by a pre-established question. It is thus here that effect ELIZA between concerned. The person is misled by her experiment and associates more direction with the conversation than it is not really.
