He writes, “A lot of readers have suggested that I am not a helpful blogger because I refer people to other studies for data to support my arguments. These critics are probably right. Were I devoted to blogging full time, I would quote all the data and summarize all of the studies, thereby getting nothing else done. I had assumed when I started my blog messages that people would pause, think, and look up facts. A few have, but most seem to have opinions they like to express quickly. There is nothing wrong with this, except that it doesn’t advance knowledge.”
