Space Station Incident Demands Independent Investigation

Sadly, from past experience, this mindset of complacency and hoping for the best is the result of natural human mental drift that comes when there are long periods of apparent normalcy. Even if there is a slowly emerging problem, as long as everything looks okay in the day to day, the tendency is ignore warning signals as minor perturbations. The safety of the system is assumed rather than verified—and consequently managers are led into missing clues, or making careless choices, that lead to disaster. So these recent indications of this mental attitude about the station's attitude are worrisome.

Mental drifts resulting from normalcy led to diplomacy efforts trumping engineering concerns resulting in more bugs and an erosion of safety?

That sounds familiar. Maybe the problems with building software are just human problems.
