Experimental results cannot be used to verify theories due to the non-determinacy which is inherent in each universe—it can be only used to falsify theories. Fallibilism is implied in the multiverse.

“Every formula purporting to predict the sequence of outcomes will eventually fail: that tests the unpredictability. And in the overwhelming majority of universes (and histories) the surge will happen approximately half the time: that tests the predicted value of the probability. Only a tiny proportion of the instances of the observers will see anything different.”
