I rather prefer...

...over this formulation of a grad student the way John Atkinson now agrees to put it, closely following the conclusions by the test author Lipshitz himself:

"If it [reversal of absolute polarity] is audible with typical music, the effect is subtle...and this test does not provide evidence that the effect is audible with a statistical degree of confidence greater than [x]%." (My emphasis.)

If I may fill in that x for JA in his last sentence, the chances that a 60/113 result is obtained by just guessing are greater than 50% (about 58%), meaning that the score has no significance at all. His own point proven: not shown to be audible.

In other words, if audible at all, the effect is so subtle it cannot even be heard (in the tests conducted so far, in case JA disagrees with this formulation...).
