I guess my question is how do we know what we are observing is what is happening and is not being skewed by another variable even a neurological/psychological/philosophical feature?
We don't! Physics doesn't really deal with ontological questions like "what is it really?" It's all predictive models.
A growing number of employers are using surveillance wages to negotiate your next paycheck.
Still nothing to hide?
When we write programs that "learn", it turns out we do and they don't.
