Q: Given how often people misunderstand what "optimism" means in Seligman's work, why do you think he repurposed an existing word instead of inventing a new one? A: I don't know, but if I had to guess, I'd say that he is a data-driven man, and some simple A/B testing revealed that people were more likely to read a book purporting to be about "Optimism," than something they'd never heard of.
