Crew assignment is another frustrating plot contrivance. In the comic adaptation of Where No Man Has gone before they confirm that Dr Denher refused assignment to the ship so that's it, we have no psychiatrist (although in the Abramsverse she seems to be have been 'downgraded' to a psychologist i.e. she's a PHD in psychology rather than a medical doctor). It overlooks the fact that they should have got a replacement if she declined the assignment, and would have been a good opportunity to use Noel.
Of course it might be that, since the 5-year mission had not started yet, a mental health professional was not essential. It would be very silly if they still had nobody by that point.
As far as TOS goes, there are quite a few instances where McCoy or even Chapel fills in and makes do even though the ship has at least 3 doctors and at least as many nurses.
