This is a soft question so may not be suitable for this site.
The LHC famously discovered the Higgs boson several years ago, but also seems to have ruled out several hoped for versions of supersymmetry (pushing the mass range for the supersymmetric partners higher). One general problem experimental particle physicists seem to have at the moment is that it is difficult to find physics outside the standard model.
My question is: from an outsider’s perspective, the Higgs seemed as speculative as, for example, supersymmetry. We had no direct evidence for the Higgs field outside of a need for consistency in the model so that we could explain fundamental particle’s mass - but supersymmetry also purported to explain defects in the theory, resolving hierarchy problems.
Why was the Higgs included in the standard model but those other parts which had no direct evidence were not?
Given the fact that we have actually found evidence for all the pieces of the standard model, but nothing incredibly compelling for proposed extensions, there surely must be something objective which sets it apart?
