Until relatively recently most psychologists had never heard of sphericity. Most text books didn't mention it (and even now some of them confuse it with compound symmetry). The big change happened a few years ago when SPSS started including information about sphericity in its repeated measures ANOVA output. Of course, because most undergarduate text books didn't mention it people started looking for information on it. Around that time I taught an advanced course on psychological statistics and produced this resource for my tutees. It turned out that they passed the web link on to other students on the course. Once I realized it was widely used I tried to keep it fairly up-to-date until I moved jobs and my web pages became homeless.

I've no idea.

Some time ago I had the idea of a blog about the kinds of statistics I use in my work. I didn't really think much about it until I noticed a couple of blogs by a friend of mine (Learning Statistics and Applying Regression by Jeremy Miles). Jeremy's blogs pointed me to the excellent Statistical Modeling, Causal Inference and Social Science by Andrew Gelman and Samantha Cook.
