Hi Linda

Can I ask what your source is for the 25% hit rate due to chance? This is new to me.

When you raised Sheldrake I did some research on him and found that figure. I'll have to dig around for it now, I should have bookmarked it but didn't. The gist of it was that his research, which gave four options so chance would dictate 25% hit rate by chance alone, when replicated produced no positive results and failed to support his findings, in other words they returned the 25% success that chance predicts. I'll have a dig around and see if I can find the couple of articles that discussed this and I'll post the links.
