 In an example like the one mentioned it is reasonable to think that we discover the correlation between Houdini’s predictions and the subsequent outcomes of the tossed coin by comparing the semantic content of the predictions with one of the two iconic sides of the coin that define the semantic content. The side facing up determines whether the prediction is true or not. First, in order to establish a causal correlation between the content of the predictions and the outcome of the tosses we would look for a high percentage of correct statements made by Houdini. This is an epistemically necessary condition for establishing a causal correlation. Second, there cannot ontologically be a causal correlation between the semantic content of Houdini’s prediction and the (reading of) outcome of the head or tail if no flipping of the coin takes place. His predictions would not carry any truth-value and we would think of them as pure guesses. Hence, when someone attempts to bilk this experiment, he or she will either arrange the outcome opposite to the content of Houdini’s prediction or abstain from flipping the coin.
