Gary Klein's "Sources of Power: How people make decisions" arrived from Amazon.  I've started reading it and so far it is fascinating.   Klein starts off by explaining rational choice theory and immediately sets out explaining why this approach (measured analysis of various possible decisions to arrive at a maximally efficient decision) is diametrically opposed to the way decisions are made under duress and time pressure. 

Foundational, it is.  Somewhat distracting from my other project, it is as well.

However, I've given it some serious thought, and IF I had three weeks to spend dedicated to my other project, I'd be wrapping that puppy up before the end of April.  Since I don't, it's going to take me three months.  Context switching alone means that I can't jump into that project unless I have a serious block of time to dedicate to it.  Compare this to reading foundational literature which, unlike paper reading, requires little in the way of blocking out and meta-tagging... it's easy to pick this book up and read a few dozen pages and find a good place to stop.
