Anti-fragility

Shaming as a behavior-modification strategy has poor empirical support, producing avoidance and resentment rather than lasting behavioral change. Research identifies later adolescence as the optimal developmental window for experiencing significant adversity; trauma earlier is overwhelming, while trauma too far into adulthood finds a person without prior incremental toughening. Moderate stress applied at the edge of the comfort zone produces growth, while the absence of challenge produces fragility. The decline in children's independent activity, driven by parental overestimation of rare dangers via the saliency effect, removes the incremental adversity exposure that builds adult resilience.
