When Pizarro defeated the incas why does diamond use historical anecdotes to support his argument instead of other kind of evidence such as statistics?

Diamond uses historical anecdotes to provide concrete examples and make his argument more relatable and engaging to readers. Anecdotes help to illustrate the broader themes and patterns he is discussing, such as the impact of European technology and diseases on native populations, in a way that statistics alone might not capture. By including historical anecdotes, Diamond can also draw on specific events to support his arguments about the broader consequences of conquest and colonization.
