Narrative:
Departed dfw runway 17R. Departure control gave us a turn to a heading of 350 degrees. The copilot started a turn to the left. I thought the controller had given us a turn to the right and advised the copilot. After rolling into a turn to the right, we verified the direction with departure control and it was a left turn. We immediately executed the turn to the left. The speed at which instructions and readbacks are give due to congestion, habit, familiarity, etc, can and does cause confusion. Congestion then makes it difficult to verify the instructions.
