I'd love to read more about this, in all aspects of astrophysics! It's not that I doubt that astrophysicists take this into account, I'm sure they do! But when we see an "image of a black hole", that's really a gazillion data points from a multitude of different observatories, processed by human made algorithms with human made models and biases, and it happens to look just like we expected - how do we know it's not just our assumptions that made it into the processing and modelling? Again, I'm sure every astrophysicist ever has thought about this and knows how it's handled, so it's not a criticism. I'd just love to read more about it, as a layperson :)
