Evidence for retrocausal interpretation of QM?

Click For Summary
SUMMARY

The recent experiment discussed in the article from Phys.org provides weak evidence supporting the retrocausal interpretation of quantum mechanics (QM). The experiment demonstrates that utilizing information from both before and after a measurement significantly improves the accuracy of predicting measurement outcomes. This finding does not falsify other interpretations such as Bohm or Everett but raises questions about their ability to account for the results. The original article on arXiv offers a clearer understanding of the experiment's implications.

PREREQUISITES

This article about a recent experiment was just published the other day: http://phys.org/news/2015-02-hindsight-foresight-accurately-quantum-state.html

I can't help but think that this is at least weak evidence in favour of the retrocausal interpretation. Of course other interpretations aren't falsified by this, but how would for instance Bohm Or Everett account for this result?
 
Unfortunately, the phys.org article is very badly written. All the experiment did is show that if you use information from both before and after a measurement to guess the result of that measurement, your chances are much better than if you use only one of the two. Not terribly surprising and completely in accord with any interpretation you like.

If it was true what's suggested in the phys.org article, it was either big blunder or a sensational new result going beyond all of known physics. As all physical theories, also quantum theory is strictly causal. I suggest, to better read the original article to make sense of it. It's on the arXiv:
