Can you call it an observation if the lens you are using may be faulty?

If you use many lenses you can assure yourself that they are not all faulty in the same way. This is why we can safely say that dark matter is observed fact, because we observe it in so many different ways.

We see many datapoints gatheredbl by multiple technologies and approaches, but they all use the same cosmological model. The same lens.

Maybe lens was the wrong word. All the data gathered is interpretated using the same brain.
