When verbal and non-verbal messages are contradictory, it is said that most…

Concept

Every message travels on two channels at once. The verbal channel is language itself — the words spoken or written and their literal content. The non-verbal channel is the behaviour that accompanies language — tone of voice, facial expression, gesture, posture, eye contact and use of space. When both channels carry the same meaning the message is congruent; when they carry opposing meanings it is an incongruent or mixed message.

The governing principle for an incongruent message is non-verbal dominance: the receiver resolves the contradiction in favour of the non-verbal channel. The reason is control. Words are consciously selected and can be rehearsed or managed strategically, whereas much non-verbal behaviour is spontaneous and habitual and therefore leaks the sender's actual state. Albert Mehrabian's studies of inconsistent messages about feelings and attitudes are the classic empirical statement of this principle.

Application

The stem specifies exactly this incongruent case — verbal and non-verbal messages that contradict each other — and asks which channel the receiver trusts. Applying non-verbal dominance, the receiver believes the non-verbal messages.

Example: a colleague says “I am perfectly fine” while avoiding eye contact, speaking in a flat tone and sitting with slumped shoulders. Listeners come away convinced that something is wrong. They have set the literal words aside and read the tone and posture instead — precisely the non-verbal channel.

Contrast with the other choices

• verbal messages: the channel of the words themselves. Because word choice sits under the sender's deliberate control, this is the channel an audience discounts when it clashes with the behaviour it can observe.

• indeterminate messages: an indeterminate message is one whose meaning stays ambiguous or unsettled. That label classifies how clear a message is; it is not one of the two channels the verbal/non-verbal distinction names, so it is not a channel a receiver can fall back on.

• aggressive messages: aggressive, alongside passive and assertive, names a communication style — the manner in which content is delivered. A style can be expressed through words and through tone alike, so it lies on a different axis from the verbal/non-verbal channel split that the stem is about.

Result: when the two channels contradict each other, most people believe the non-verbal messages.
