Consequently, we can be "smart" in different ways over time: we can be highly productive learners, we can put a lot of effort into learning, we can have accumulated domain expertise over time, and we can be smart in how we engage in praxis—the application of knowledge. Ironically, the half-life of domain knowledge, which is often inversely related to our collective knowledge, can make us, as individuals, less smart.
