Also, it's true that Terrell's mission did not call for great haste. But slowing down and taking stock is not a game-changing move in this particular case (Khan's invisible settlement wouldn't have become any more visible with waiting) - and it isn't that in the general Trek case, either.
Fundamentally, Khan's presence is a case in point against trusting records. Either those records tried to hide Khan's presence, or then had the harsh but recognizably not desert-like CA V flagged with it - both options meaning that heroes trusting those records would be likelier to stumble onto Khan than heroes trusting their senses and sensors. Starfleet regularly encounters unexpected dangers of this very sort, surprise ambushes by entities never before encountered or never expected to show up where they do. Being prepared for such eventualities is what would define professional. And with such preparedness, studied preconceptions become fairly irrelevant.
ST2 also explicates what was implicit in TOS: that the left hand of Starfleet does not know what the right hand was doing a decade or two earlier. Kirk often dictated deliberately misleading logs, and sometimes downright forged his records. His assessment of what just happened was subjective and haphazard at best even when he didn't try to obfuscate. Sooner or later, something like ST2 was bound to happen - and the more probably, the more faith Starfleet put on its own records and the less it trusted its realtime assessment of the situations at hand.
