You just carelessly forgot to mention the disinterested observers who monitored both the participants chosen at the last moment, as well as the contents of the messages, written at the last moment. Right?
Double blind my elbow!
How detailed will one be in a post such as this? We were careful; and, I'm not some ordinary fool. If you doubt this, how about trying this out for yourself? Nothing like refuting someone without any standing in the issue. That is totally blind, young-un.
So, did I type a summary, or a detailed report? To the truely intelligent, a few paragraphs spanning two or three years would be regarded as a summary.
I suggest that you conduct your own experiment. With no experience whatsoever in this matter, your assumptions taken in place of knowledge have no standing. Much less so than mine, wouldn't you expect?
