All Italians talk with their hands

I'm Italian. I talk with my hands. I can say this.

This recent blog by Jonathan Farrington covers Social Style concepts in detail. They did a good job describing each style. Until they starting describing styles as equivalent to roles and results.

Does the blogger commit the sin of assigning business roles to certain social styles? Are all successful salespeople Expressive? Are all high achievers Drivers?

My experience in facilitating says no.

The statistics say no, too.

What do you think?
