I was interested in firearms as a child (and an older child... right up till now). A 9mm parabellum round is 9x19mm is size and has a higher muzzle velocity than the 0.45 calibre round in M1911s (aka Colt Government) but due to the wider impact area a .45 has a higher degree of stopping power because it can transfer the energy faster. Oddly rounds designed to get around this flaw also include safety rounds which won't penetrate an aircrafts shell.
I could go on. All details pertaining to something I'm interested in. Oh and I notice the details of weaponry in films before my ESTP wife who is entirely ignorant of them as she only has a passing interest in guns and only from a point of shooting them.
However read me a list and I'm asleep by item 3 (mentally anyway).
The best way I can figure it is that Holmes is interested in crime. An obvious statement but one which makes serious implications.
How fast do you note whether a person is extraverted or introverted compared to one of your Se users who's not interested in psychology?
It fits a framework but not necessarily centred around that individual experience but as a whole of experiences gather throughout the lifetime of the interest.
