I think there’s a very interesting debate about what knowledge is, what it means, and how we come to the idea of “knowing” something or at least believing it to be true.
It’s why one of my degrees is in philosophy.
That being said, you don’t proffer a very coherent argument. I’m not sure what trusting my senses has to do with anything (unless you think poor eyesight caused me to misread the study?) and if you’ve got a better way of examining evidence that our current clinical trial system I’d love to see you write it up and publish because that’d be amazing. If I do have an ideology, it’s that we should base treatments on evidence, for which the current best method we have is a clinical trial. It’s not perfect, but it’s a damn sight better than trusting our thoughts and feelings because people (as you note) are basically the worst.
