Faster-than-light effects seen in quantum disentanglement experiments transmit quantum randomness rather than information.
Mostly true True in substance, wrong in a detail.
Factual: Statements about the present or the past, checked against the record: did they hold up?
What would count as true or false
Judge as of 2002-12-12. True: the mainstream physics consensus (e.g. the no-communication theorem) holds that correlations between entangled particles, including in experiments described as showing faster-than-light effects, cannot transmit information faster than light, because each party's local outcomes are random. Mostly true: the core point (no superluminal information transfer, outcomes locally random) is right, but the wording is a little imprecise, e.g. calling it 'disentanglement' or 'transmission' of randomness rather than nonlocal correlation. Mixed: physicists are substantially divided on the point. Mostly false: the 'no information' part is right but the claim's description of what happens is substantially misleading. False: established physics shows entanglement does allow faster-than-light information transfer.

“However, it is now well understood that quantum entanglement does not allow any influence or information to propagate superluminally.”

E2 Faster-than-light communication Wikipedia · 1 November 2001
“Entangled states lead to correlations in the results of otherwise random measurements, even when the measurements are made nearly simultaneously and at far distant points.”

E3 No-communication theorem Wikipedia · 10 February 2005
“It asserts that during the measurement of an entangled quantum state, it is impossible for one observer to transmit information to another observer, regardless of their spatial separation.”

E4 No-communication theorem Wikipedia · 10 February 2005
“In 1978, Phillippe H. Eberhard's paper, Bell's Theorem and the Different Concepts of Locality, rigorously demonstrated the impossibility of faster-than-light communication through quantum systems.”
Reasoning
E1 says entanglement does not let any influence or information travel faster than light. E2 describes entanglement as producing correlations between measurement outcomes that are otherwise random. E4 dates a rigorous proof that quantum systems cannot be used for faster-than-light communication to 1978, well before the claim, and E3 sets out the no-communication theorem. So the core point is mainstream physics: no superluminal information transfer, with random local outcomes. The wording is a little loose, though ("disentanglement" and "transmission of randomness" instead of nonlocal correlations), so it fits the criteria for mostly true.
