if the psychologists have tackled that problem

[Kolridg]

Could you please tell if in the last remark the phrase "if the psychologists have tackled that problem" suggests that K wonders if there have been any tries to tackle that problem, or if it suggests that K wonders if psychologists have started to tackle the problem in the past and still tackles it. In other words, I can't understand if "have tackled" is a case of the present perfect where we focus on the action (or on its result like many says) rather than on the time when it was done, or if it is a case of the present perfect where the action has started at some point in the past and still continues in the present.

Jiddu Krishnamurti. Discussions with scientists. Part 1 "Roots of psychological disorder"
4:14 - Yes, but I mean, if you go all over the world...

"K: Yes, but I mean, if you go all over the world, it's the same expression, it's the same way of living. They're all living their personal lives, unrelated to another, though they may be married, they may do all kinds of things, but they're really functionating from an isolated centre."

"H: And that centre, that self, is the source of the difficulty in the relationship?"

"K: Relationship."

"H: And the difficulty that creates the symptoms." (symptoms of psychological disorder)

"K: And I wonder, if the psychologists have tackled that problem, if the self is the beginning, the origin of all contradiction, divisive activity, self-centred activity, and so on."

He's asking whether there have been any attempts by psychologists to address that problem. There's nothing implied about the attempts being unsuccessful or ongoing or anything else. He's genuinely curious to know.
