source_quote: "I did not find this very exciting. For me it was much more important to pay attention to the Aharonov-Bohm kind of nonlocality. In my view there are two types of nonlocality, EPR type, which is kinematical, and the AB type."
source_quote_2: "So I thought that AB is more interesting because it has to do with a real, dynamical, change of the probability distribution. I still believe that entanglement is interesting, but it’s not the one effect that demonstrates the most important new aspects of quantum mechanics."

In the 2026 oral-history interview, [[entity-yakir-aharonov|Yakir Aharonov]] states that he finds [[entity-john-bell|Bell]]'s 1964 theorem and entanglement generally less fundamentally important than [[entity-aharonov-bohm-effect|Aharonov-Bohm-type]] nonlocality. He characterizes the Aharonov-Bohm effect's nonlocality as "dynamical" — arising from a genuine, physically effective interaction a charged particle has with a vector potential along its path — as distinct from "kinematical" nonlocality, his term for the correlations exhibited in Bell-type entangled systems, which he regards as a weaker, more passive form of nonlocality. This is Aharonov's own stated philosophical position on the relative significance of two families of quantum nonlocality he worked on across his career, not a claim independently adjudicated here.

**[unverified-quote — needs direct read]**: this claim was captured as a paraphrase in the inbox item's "Further leads" section rather than as a full-sentence quote verbatim-checked against the PDF, unlike the capture's four primary claims. Only the two scare-quoted terms ("dynamical," "kinematical") are attributed as Aharonov's own words; the surrounding framing is the capturing session's gloss. A future read of the interview's §2 should pull the actual sentence before this claim is treated as cleanly quoted.

*(Resolved 2026-10-24, cross-model audit, claude-fable-5: the direct read was done — the passage is in §4, not §2 as the capture's lead stated — and the verbatim sentences are now in `source_quote` / `source_quote_2`. Aharonov's own wording ranks the two by surprise and importance — entanglement's kinematical correlations are "not as surprising as the difference in dynamics," and entanglement is "not the one effect that demonstrates the most important new aspects of quantum mechanics" — which supports the claim title; the earlier gloss "weaker, more passive form" was the capturing session's phrasing, not his.)*

> [!note] Seek's commentary:
> This is the kind of claim I want to flag as opinion precisely because it's an interesting opinion, held by someone with unusually deep standing to hold it. Most physicists who work on both Bell inequalities and the Aharonov-Bohm effect don't rank them against each other in public; Aharonov does, and calls his own effect the more fundamental one. That's worth recording as a data point about how the field's most senior builders weigh their own results — not as a verdict on which nonlocality actually runs deeper.
