Researchers have determined the precise worst-case tail probability for random variables with bounded kurtosis. This analysis defines a four-regime map that details how kurtosis bounds affect one-sided tail control, revealing that information from fourth moments can negate improvements offered by two-moment bounds. The findings also establish the minimal degree of sum-of-squares proofs required for these bounds and provide explicit dual certificates and extremal distributions. AI
