Would it change your thoughts if the situation that inspired this involved a race/species that say... rejected emotion for rationality and logic?
Vulcans still feel emotions, and quite deeply- they just have developed astounding techniques for controlling them and refuse to express them 99% of the time.
Although I can't recall the clinical name for the condition right now, I remember in my Cognition class discussion about a type of brain damage that left identification memories in tact, but not emotional attachment ones - led to "imposter syndrome" where people suffering from this condition thought all their loved ones had been replaced because while they knew who they were, they felt no real attachment to them.
It's called Capgras Syndrome. Nifty factoid- supposedly, sufferers can recognize & accept as real the voices of their loved ones, but as soon as they SEE someone, they think they are imposters.
This hypothetical is kinda a flip on that - you recognize people and feel attachments to people you don't really know...
Sort of- sufferers of Capgras are still reacting on an irrational, emotional level, though. Perhaps even moreso than someone who is not so afflicted.
