“Thirst for knowledge.” That actually turns out to be completely true, studies prove it. The human (and other animal) brain signal the body to release a stimulant as a reward for learning. Pinker’s “if you were to design a being, you’d give it the same qualities” math applies here, too – a system that rewards continued learning, guessing, probing and speculation keeps a species safe from predators. In the end, perhaps, it is not a thirst for knowledge so much as a love of life, but at least I feel a little better about my 2 hour jaunts on Wikipedia. This is life or death, ppl!
Here’s an excerpt:
“Dopamine neurons are thought to be involved in learning about rewards – by adjusting the connections between other neurons, they “teach” the brain to seek basic rewards like food and water. Bromberg-Martin and Hikosaka think that these neurons also teach the brain to seek out information so that their activity becomes a sort of “common currency” that governs both basic needs and a quest for knowledge.”
