For me, what this post illustrates most is the cost of information. By making hasty decisions, buyers are trading present time that might be spent shopping and comparing with future time spent struggling with the wrong product. They're discounting future time. But they're also doing something very rational -- they're making a decision to see what happens. That is, they're testing a hypothesis in the only way the market allows them to. Because people are bad at predicting their own future needs and behavior, and products are bundles of features whose importance is often unknown until you have to use them in high-dimensional futures. So buying is an empirical test.
Unfortunately, most consumers, recruiters and sometimes hiring managers are in a position of information assymetry vis a vis the people selling them something. That is, consumers rely on the self-reporting of vendors which purport to be experts.
