As long as you're open to precognition, here's one way to think about the "Memory Supercharger" included with the PhotoReading course.
To quote from it, "Your memory bank is like any other bank." Banks can offer loans. Savings in banks can generate interest. Find your own ways to stretch the metaphor... essentially if your memory has the ability to recall facts before they happen, then the Memory Supercharger will enhance that ability.
"Einstein Factor" goes into some theories about how precognition is most likely the processing of cues not recognized by the conscious mind. Sometimes, the other-than-conscious mind won't provide the evidence that supports a hunch. Prime example is PhotoReading itself. When you remember a fact, you rarely remember the exact wording of the fact or the page number. Your-other than-conscious mind discards the "context" the same way you'd throw away the wraping paper and packaging materials of a gift.
The easiest way to train intuition is to test it. This creates trail and feedback, and allows you to distinguish between inaccurate and accurate intuition.
Ah, but I ramble. Enjoy your PhotoReading.
