How can I learn more about logic and it's relation to psychology, persuasion, and communication? I want to become a more rigorous scientific thinker and to improve my ability to communicate scientific concepts in a clear and convincing manner.

The reason this comes up is that I've been talking to this friend/acquaintance a lot lately, and he is really misinformed on a lot of issues concerning science and technology. I want to educate him a bit on these issues, but no matter what I do or say, he wont be convinced. I tried calling him a poltard, I tried calling him a schizo. I told him that he's a scientifically illiterate right-wing moron. I told him to take his meds. I insulted him for coming from a blue collar background. None of it is working, and I don't understand why.

What other strategies can I employ to effectively communicate scientific ideas in a logical and convincing manner?
