I think you're easily blinded by the science if you don't understand it. That's fine, there's loads I don't understand yet, but I'm working away at that and am increasing my understanding all the time. That understanding helps me in a practical sense to make the best decisions for my dogs based on what I can see in them. I don't expect everyone else to feel the same, or to seek the same level of understanding as I strive for as not everyone is as interested in it as I am. That's cool; I'm not the slightest bit interested in music, but can still appreciate that people are, and want to get as good as they can at it - and again with music, there's the technical, mathematical side to it that complements the artistic side. There is also the strong cultural side that influences what we think makes good music in one country, compared to people from another country whose music sounds discordant to our ears. Your average musician is probably interested most in the instrument they are playing, to get as fluent at that as possible. They may dabble into the technical side for transposing and the like. But there is a vast subject beyond that that brings the art and the science together. Just because someone is interested in the science it doesn't mean they can't also strive for the practical skills, and studying the technical side can improve someone's skills as they learn the rules that govern what makes things sound good.
Understanding the science doesn't make you a good dog trainer, but if you do understand the scientific principles that are at work, you are in a better place to make better decisions within the confines of your skill set. You are also better placed to improve those practical skills.
What I'm saying is that it can never be a bad thing to want to increase your understanding, and we shouldn't to try to reduce the importance of the science that governs a subject - any subject. If you're not interested, that's fine, but for those of us who are, it provides clarity, it doesn't add confusion. For those that are confused by the conversations in this section of the forum, your choice is to either start smaller and increase your understanding incrementally until you do get it - and by all means ask as many questions as you'd like; or else make the decision that the science isn't of any interest, and keep doing what you're doing without it. There's no right or wrong.
