Narrative:

Descending through FL200 for 11000 ft MSL, the center assigned a 20 degree left turn for traffic. The first officer was flying and had made a right turn instead. I was doing checklist and setting up the FMS and did not notice a turn in the wrong direction. When I looked up, I noticed the error. At the same time center was asking about the turn, too. I monitored TCASII, and saw no aircraft inside 1000 ft or 5 mi and we turned to the heading that we were supposed to be on in the first place.
