It is that thinking about humans as meat robots that aren't blessed with free will makes you unable to understand them, help them, make them happy, support them etc.
> My personal observation is that most people who self-identify as lonely lean heavily towards intellectualism and wanting to understand things instead of emotionality and being happy with intuition.
They are emotional too. Pretty common phenomenon about contemporary people who lean heavily towards intellectualism is that they rationalize and explain away their feelings and emotions based decisions.
What you call being happy with intuition is sometimes taking into account complexities that can not be neatly simplified.
For example, the honest truth is that they did something out of anger, fear, wish to show up, but they will go out of their way to frame action as thought out and logical. Their opinion may be actually subjective, based on sympathies and feelings, but they will spend hours constructing elaborate arguments for why the feeling was actually objective.
This makes it harder to reason about other people too and harder to understand complex reasons behind why others do what they do.
