These findings disappointed many physicists, who believed that supersymmetry (and other theories relying upon it) were by far the most promising theories for "new" physics, and had hoped for signs of unexpected results from these runs. Former enthusiastic supporter Mikhail Shifman went as far as urging the theoretical community to search for new ideas and accept that supersymmetry was a failed theory. This opinion is not universally accepted with some researchers suggesting that this "naturalness" crisis was premature because various calculations were too optimistic about the limits of masses which would allow a supersymmetry based solution.
