But it's less concrete with other "sciences" like evolutionary psychology, behavioral economics. Even cosmology & theoretical physics is taken more on faith than trust. What observations of the multiverse or string theory can we build our trust on?

And medicine , molecular biology have also had mixed results, to the point that many beliefs were taken on faith (e.g. dietary vs blood cholesterol)

My point is don't lump all the "sciences" together in one lot of "the science"– there's a spectrum of observability and corroboration depending on the field.
