## AI overview

This commentary compares Matthew Syed's Bounce and David Epstein's Range, relating their arguments about deliberate practice, specialization, and breadth to security work and threat-modeling training. It argues that security skills can be developed through deliberate practice rather than requiring an innate attacker mindset, while recognizing the value of experience across fields.

## Source excerpt

I want to talk about two books: Bounce, by Matthew Syed and Range, by David Epstein. I want to talk about them together in part because Range is explicitly framed as a response to Bounce.
