How important are those conversations that take place by the water cooler? Sometimes just observing whose taking part in the conversation can tell you a lot about their personality. For example, an Inspiring, outgoing type will probably be the ringleader. The Dominant style will stride by (usually in a hurry) and will not take part in the conversation. You may see the Supportive style peeking out from their desk to listen, but not take an active role. And finally, more often than not, the Cautious, reserved types bring their own industrial size water bottle to the office.
