No it isn't lol. You can tangibly observe, experiment, and interact with the placebo effect/pharmaceuticals. There is a literal method that is used to prove things like the placebo effect.

Faith (from the religious understanding) is for that which can't be proven, thus antithetical to science. And before I hear something bogus like "faith in the method": that method has proven itself millions of times over with physical tangible proof.

Hell if you Google the definition of faith the second one is literally "strong belief in God or in the doctrines of a religion, based on spiritual apprehension rather than proof."
