I like your answer because there is something strange about generalizing a group of people who have dug deep enough down that rabbit hole. Are there signs of a newbie "person A" to a field that they would have more potential to always take on a problem in a better way than "person b". What if einsteins work never involved mathematics and he wrote mysteries about a detective and from his books we could tell this person understands taking on problems and how to learn from failing etc,etc..
