When I was in school I studied mathematical logic and proofs, thinking on how to prove stuff on my own as practice.
This can be useful to be able to influence others visa logical, undeceitful thought.
However, there is a catch. If the other person is unable to follow your reasoning, convincing someone this way won't help. After all, ask those years of practice will mean you will have a skull which will not be appreciated by others.
In the end, what influences the population at large is marketing techniques, not logic.
I would like to know your perspectives on this point of view, arguments in regard to this matter or counterexamples.
I hope to encounter positive constructive examples in your answers.
