This reading based routine was born out of the back of wanting to learn to cold read and not having a clue where to start. I wanted a sure fire way to give a reading and not have to worry about being wrong and ensure that even if I was a little more bold and fired out something less ambiguous (in terms of statements) and I lost my way, I would always have the confirmation of a big hit to finish with. There are two major principles at play to make this work.
One I call the 'pigeonhole' principle and the other is a mild version of my 'confirmation' principle.
