Start by measuring things that you can measure.

Perfection is the enemy of good. If you know that you can't achieve "perfection", and that stops you from aiming for "good", then we lose in the process.
I agree with this. Throwing the baby out with the bathwater does't solve anything. Otherwise, we all go back to arguing based solely on what we (think we) saw.

As far as measuring everything at once, I see two approaches:

- using linear regression, which assigns numerical importance (coefficients) to competing factors without having to try to integrate measurements for multiple factors simultaneously

- design the study in such a way that it essentially filters out many factors which are difficult to measure and/or unknown
