Excellent article Jason as usual. I think there are at least two attributes to be considered:
1) A healthy skepticism as part of one’s nature
2) A character which shows obsessive compulsive traits; not to the point of pathology but a certain orderliness and thoroughness which is required in all professions.

Cordially,
