It's not a matter of 'tend to pick a high iso', the camera does not have any options! You fix two parameters, so it needs to adjust the third one. Slow or fast adjustment does not play a role here, that's only applicable when the camera can choose two parameters (e.g. shutter speed and iso).
This is my understanding how it works.

Wait till you used a CCD based camera (e.g. K100D or K10D) and you will never complain again
It's always a balance; FF also has limits although a bit further away
Do you want the shot and accept the noise, or do you not want the shot.
