It seems 'scientists' use something called intuition
to achieve results.
But what is it?
Intuition is invisible.
Intuition is so intangible that you can't analyze it in a laboratory.
[ironic, considering that ESP experiments have been done in
laboratories...with mixed and controversial results].

Intuition defies explanation.

While most scientists consider ESP to be something along the lines
of mysticism/occult, they don't hang that label on intuition.

Where am I going with this?
Robert Park is labeling those things that fall into religious
or mystical practices 'superstitious'.; partly because they
are intangible or invisible.

IOW, Mr. Park is an "existentialist" who believes that if it
isn't within the ability of "science" to analyze, observe
or detect then it's either a myth or quackery.
Mr. Park forgets that science has revealed strange, even invisible phenomena over 300 years that were originally classified
as nonsense.
