Evidence for retrocausation in the field of psychophysical phenomena is to date questionable. Associated successful theoretical formulations would have to make accurate predictions and the purported evidence would have to be independently replicated. It is shown here that purported evidence for retrocausation within the field of psychophysical phenomena, such as the hypothesis of micro‐PK —that the statistical distributions of random processes are mean shifted by thought alone— can find more satisfactory descriptions. Those do not necessarily invoke transfer of information backward in time, while they provide mathematically structured formulations and allow for clear predictions. They refer to a two‐state Markovian process characterized by equal self‐transition probabilities, p=q>50%. This Markovian behavior introduces persistence and clustering of like binary states leading to a broadened scatter of statistical averages of individual micro‐PK tests about their theoretically expected mean, namely 50%, corresponding to that of an unbiased process. The origin of this broadening mechanism is currently unclear. It is, therefore, argued here that an established theory of mind‐matter interaction should precede the investigation of the validity of retrocausation within psychophysical phenomena. Thus the correct theory can be decided among alternatives.
Abstract In this letter, we will investigate causality in string field theory using pp -wave light-cone gauge string field theory. We will generalise the Ramsey scheme to string field theory, and use it to analyze string field theoretical processes. An explicit characteristic function for interactive string field theory will be built using this string field theoretical Ramsey scheme. The average of the difference between the initial and final values of any operator described in string field theory will be obtained using this characteristic function. We will use the quantum information theoretical technique based on quantum Fisher information to extract information about such string field theoretical processes.
