You can find some kind of objective metric, e.g. bug count or time spent developing new features. That alone is super hard to get right, but even if you could, it wouldn't necessarily tell you which techniques lead to a better result. People have tried studying such things (e.g. do static types help) and the studies rarely come up with any effect.

I don't think that's necessarily because these things don't have an individual effect, but because there are humans involved and so, personal ways of thinking probably play an outsized role, so technique X might be a very good fit for person A, but not for person B.
