Received our DCL [Datalinked Clearance] which directed the VIBOS8Y departure but I misread it and saw the VIBOS9Y departure. This was what I expected to see based on my preflight study which indicated that the 9Y was the more direct routing to point VIBOS and the other departures were 'by ATC'. I had preloaded this in the FMS and let my FO know it was there along with my reasons for choosing it. I read the DCL from a printed copy and I believe my expectation bias captured the FO as well. We then briefed and flew the VIBOS9Y. A query by the controller on departure as to what SID we were flying caused us to review the DCL (printed copy) again and we discovered our error. Of course; there were interruptions to our flow by ground personnel but no more than normal. I allowed my attention to detail to falter.Captain failed to ensure clearance was correctly loaded in the FMS.I will return to my normal habit pattern of double checking the DCL clearance with the FMS programming pages after all briefings are completed.
A B777 flight crew departing ZGGG programmed an incorrect SID into the FMS and were advised by Departure Control when they diverged from their clearance.
