Abstract
We prove that a strengthened version of Minač–Tân’s Massey Vanishing Conjecture holds true for fields with a finite number of square classes whose maximal pro-2 Galois group is of elementary type (as defined by I. Efrat). In particular, this proves Minač–Tân’s Massey Vanishing Conjecture for Pythagorean fields with a finite number of square classes and their finite extensions.

The author wishes to thank I. Efrat, E. Matzri, J. Minač, F.W. Pasini, and N.D. Tân, for several inspiring discussions on Massey products in Galois cohomology and pro-p groups of elementary type, which occurred in the past years; and the anonymous referee for the helpful comments.
