True Story. For a time I worked in an art shop. We had many a quiet day, and I understand the shop isn't there any more.
Anyhew, this was back in my shut-eye days. I had a great interest in ESP and the paranormal that was, back then, fuelled by belief. These days I still have that interest but it is fuelled by disbelief.
But I digress. I had learnt that there was a famous Japanese technology company that had sunk quite a chunk of change into investigating ESP. The story ran that although they had assured themselves that psi existed, they really couldn't see any way to a marketable product involving psi, so had abandoned their research. I suspect looking back that there is a bit more to this story than meets the eye!
The key experiment, as described in whichever rag I had read the story in, involved taking a small piece of paper, drawing something on it, folding it up and, wait for it, sticking it in your ear. Someone else was then charged with concentrating on what the drawing might be.
And with little to do and more stationery than we could sell, I proposed we tried it out.
So I drew something, stuck it in my ear, and my colleague took up a bit of paper and attempted to determine what I had drawn.
He turned his drawing to face me and I paled. His drawing matched mine.
Now stop me if you've heard it, but we'd both drawn a house.
What I love about this is that we couldn't dismiss the effect, even though subsequent attempts at the experiment all failed. Consider, we explained, the millions and millions of things we could have drawn...!
