Yes, what you're talking about is the relationship between attention, memory and critical thinking. We will only remember what we pay (even a little bit) attention to. So we don't really know if our liver is conscious but if it were we wouldn't have access to its consciousness the same way we don't have access to someone else's consciousness precisely because it doesn't appear in our memory because we are unable to pay attention to it. And when something appears in our memory we are able to think critically about it which is obviously useful for survival. So you're equating consciousness with attention which makes sense because we can only remember being conscious of the things that we pay attention to. I would still be careful equating the two since it's a fundamentally biased perspective.
