We study symmetric unions in the context of problems regarding knot invariants. Recently, a class of symmetric unions was proposed to construct nontrivial knots with trivial Jones polynomial. We show, however, that such a knot is always trivial and hence this construction cannot be used to answer the open question asking whether the Jones polynomial detects the unknot. We then discuss why symmetric union is a valuable construction to study knot invariants and why our result provides strong evidence for the non-existence of nontrivial knots with trivial Jones polynomial.
