The Importance of Similitude in Popper's Epistemology

I'm not a philosopher and I hate philosophy. So you can't expect me to be like really on the ball with philosophies out there as I don't study these and I don't care. The fact is, is that there is a somewhat positivistic nature to Popper's epistemology if you're talking about very similitude rather than truth. And I'm arguing that very similitudes is actually more central to Popper’sEpistemology than truthTruth is super important part we of his Epistemology but really it doesn't matter if there is a theory or not. If truth of the theory mattered then yeah maybe I should care about sawdust
