What do Davids actions and statements reveal about the authors point of view?

In his first foray into psychology, Malcolm Gladwell approaches David and Goliath as a persuasive book designed to convince the reader to lean into adversity. He begins the book with the claim that very frequently the unexpected occurs where, against all odds, the underdog comes out ahead. He then proceeds to recount story after story where this has been true. Including numerous charts, social science research, and statistics, Gladwell presents all the data he can to back up these stories as more than exception.
