We exhibit a linear threshold function in 5 variables with strictly smaller noise stability (for small values of the correlation parameter) than the majority function on 5 variables, thereby providing a counterexample to the "Majority is Least Stable" Conjecture of Benjamini, Kalai, and Schramm.

When Majority Fails: Tight Bounds for Correlation Distillation Conjectures
Nearly tight bounds characterize the noise regimes where the Majority is Least Stable and Non-Interactive Correlation Distillation conjectures hold for Boolean functions of dimension n≥5, with full validity for n=3, p...
