Isn't that a bit extreme? Sure we don't have "the answer" but saying that the amount of things we know about how our brain works, from behavioral rhings how can our perception system can he tricked, biases in our cognition modes, the mechanism of memory and how it fails ... down to more low leven things about how the neuronal tissue works, neuroplasticity, the effects of brain injury on cognition (my favourite is when patients subjected to corpus callosotomy probably function as two independent brains and yet the individual cannot tell from inside, it doesn't "feel" like two people).

There is tons and tons of research. As with all of science there is tons of crap among the good work. As with all of science, it requires a lot of work to understand the state of the art and build upon it.

Dismissing all of that says more about you than about our scientific understanding. Yes, we humans do prefer simple explanation that fit in our heads and that are easier to achieve. That's why so many people find more compelling to believe in conspiracy theories of various kinds: they offer a clear cut, simple and total explaination instead of the messy and partial understanding of a real, ongoing rational and scientific enquiry.

After all We do prefer explainations that "make sense". On a first glance, what's wrong with that? Isn't science also trying to figure out what "makes sense"?

There are plenty of examples where our intuitions clash with reality and in some case we ended up accepting that (e.g. most people can accept that we're living on a giant sphere even if it doesn't feel so), in some other cases we kinda-sorta accept it (quantum physics) and it other cases we flat out refuse to (questions around consciousness)
