The Power of Believing That You Can Improve

Carol Dweck's research splits people, loosely, into two mindsets. In a fixed mindset, ability is a fixed quantity you either have or don't, so failure is a verdict on you and a threat to duck. In a growth mindset, ability is something you build, so failure is information and a stage in learning.

She tells a lovely story about a school that grades struggling students "Not Yet" instead of "Fail", and how that single reframe changes everything about how a kid meets a hard problem.

The tie to self-sabotage is direct. If failing means you're not good enough, you'll protect yourself by not trying, not finishing, or not caring out loud. If failing just means you're not there yet, there's nothing to defend against, so you can keep going.
