Air carrier First Officer reported passing SIYOB on arrival into IAD without turning toward MIKEJ and based on ATC's comments the reporter noted that this deviation may be a common occurrence.

Narrative

Upon arrival to IAD we were assigned 1C and when switching to the final controller we requested 1R. The request was approved right as we crossed SUNYJ intersection heading toward SIYOB intersection. The controller made a comment to stay on the arrival" which I thought was odd; but repeated back the instructions. After reselecting the approach; the box loaded with the new approach and I executed the selection after asking the Captain if it "looked good." We were in light/moderate turbulence and received a request to slow to 190 kt. and descend to 4000 feet. While slowing and configuring (while keeping a close eye on both over and under speed conditions due to the turbulence) I looked down and noticed we had passed SIYOB without turning toward to MIKEJ. I mentioned the deviation to the Captain who then turned off the autopilot and began a turn back toward MIKEJ. As we were in the turn; the controller mentioned he knew we would miss the turn and gave us a heading. I also let him know we were already turning back direct MIKEJ. The controller was very professional and helpful. All of us were initially confused; as the arrival was still built out down to MIKE J and we had been tracking on the magenta line. When we were given a vector to the east and I went to extend ESTYN; I noticed the fix in line 1L was GIBBZ and immediately realized what went wrong. I told the crew I knew what happened and would explain after we were parked. Given the fact the controller made his first and secondary comments; it's clear this is a common issue. I'm not sure if the same issue would occur on all fleets; but I believe it would on my last airplane. I thought this was an important point to make and perhaps add as a safety alert on the 20-7 page."
