There is a huge difference between 'making stuff up' & maintaining a healthy suspicion of what is being presented to you.
I have found that many seem to be very happy to take the information presented by the aircraft systems as gospel these days & don't bother to check & cross-check. "Don't worry - the aircraft will tell you when something is wrong" seems to be the modern mantra. They seem to be content to deal with the issue when it becomes a problem, rather than head it off before it becomes a problem. Maybe I am old fashioned, but I call that a lack of airmanship.
