Observation results in third-person accounts. Immersion results in first-person or second-person accounts. A scientific theory always takes the form: conditions A as described in the third person give rise to outcome B described in the third person.
Now, theories in that format do not require philosophical materialism, that's true. But they are always mechanistic in nature, because that's what's being described: how things work, not what they mean, how they feel, or what should be done.
