What’s the difference between TIQM and Time Symmetric QM? (a

[thenewmans]

I have a few questions about interpretations that use retrocausality. I only know of 2.

1. TIQM - Transactional Interpretation of QM by John Cramer 1986
https://en.wikipedia.org/wiki/Transactional_interpretation
2. TSQM - Time Symmetric QM by Huw Price
https://aeon.co/essays/can-retrocausality-solve-the-puzzle-of-action-at-a-distance

I have my own ideas of how these might work. But I’m still trying to figure this out. I’m hoping y’all can help me take a shortcut. So I have a few questions:

1. I assume TIQM and TSQM are similar in that they both use retrocausality. Am I assuming too much?
2. What’s the main difference between TIQM and TSQM?
3. Are there any other interpretations with retrocausality?

Here is a PF Insight I wrote on retrocausality https://www.physicsforums.com/insights/retrocausality/ . There are some other programs referenced therein.

What’s the main difference between TIQM and TSQM?

Without really understand either, I see that TSQM claims to be local, whereas TIQM claims non local.

There is a sometime poster in PhysicsForums, @rkastner, who has written several posts about TI. I don't think that the two (TIQM and TSQM) are the same, even though they exploit a similar loophole in explaining the mysteries of quantum mechanics.

I'm still working my way through RUTA's insights article. Looks like no shortcuts for me. I'll add @rkastner to my reading list. Thanks!
