A partial or divided response which is indicative of uncertainty in the mind of the respondent. An incongruent response can be elicited in someone by offering them incongruent communication (mixed messages) or insufficient information with which to operate. Where internal conflict is already apparent, there is a shortage of information in the individual’s own system. Incongruence can be simultaneous, as described, or sequential, in which case the subject appears to be congruent in favour of an action while in a given state and equally congruently against the same action when in a different state.
