So I'm reading Barry Schwartz's The Paradox of Choice: Why More is Less. It's a fast and amusing read (probably particularly so for me because I've seen so many accounts of the basic Tversky and Kahneman experiments that led to prospect theory—I could skim several of the opening chapters). The illustrative examples are particularly engaging. The author must be a fabulous teacher.
Overall idea: the more choices you have, the more satisfaction you expect from the decision, the harder it is to gather information about all the options, the more likely it is that you'll contrast your own choice with different choices made by others, the more opportunity for regret, the more mechanisms for disappointment. Hence higher rates of depression in affluent Western societies, etc. The author eventually advises that we figure out which decisions are actually important to us, and try to focus our efforts on making just those decisions well—where making the decision "well" includes taking into account standard cognitive biases.
I'm bad about responding to books mostly in terms of whether they feel like they're about me or not, rather than reading critically. Of course this work is mostly based on small studies where college students answer multiple choice questionnaires (at least the questionnaires are included!). Of course it's oversimplified for popularization. And it's annoying that there's no effort to connect the verbal and emotional phenomena described with underlying, say, physiological or genetic differences (not that anyone knows how to do that yet in any meaningful way).
But, it made me think differently about my life and decisions I've made and will have to make, and that's a good thing.
