tarot and i ching

Tarot reading, the use of random occurrences with assigned meanings as a diagnostic for semi-random causal occurrences maintaining no assigned meaning beyond the signified. So it is not in any means a proper mode of analysis for insight, nor a tool of divination. However, if one is looking for acausal synchronicities in thought or action, tarot may be implemented to further an understanding of irrational events, though the percentage of accuracy is indeterminable until ex post facto, as there is no test or experiment available that could possibly point out a probability of correctness. The same goes for the I Ching, stichomancy, runes, etc.
