This is an outgoing and extrovert sub-trait that has much in common with Friendliness, but with the added dimension of energy and pace. This animated style shows their interest in a topic very strongly, and their effusive nature can act as a motivating factor for others.
The nature of Enthusiasm tends to vary according to the relative level of the Dominance score in the profile. Where Dominance is low, an individual will tend to confine their expressive style to situations where they feel comfortable and accepted - they will rarely make direct criticisms or enter arguments, and are concerned about others opinions of them.
Where the Dominance score is high, however, the Enthusiastic type is much less concerned about causing offence. Where this type of profile is concerned, the outgoing and expressive style remains, but is bolstered by a more assertive approach.
