Do you ever ask a question, knowing full well, in advance, that you will not accept the answer/advice?

No, I’m stubborn, hardheaded, and a dick, but I will listen to someone else’s views.

Out of curiosity, with your question and details worded that way, do expect many (or any for that matter) people to answer “yes”?

Every. Single. Time.

I ask questions & you lovely fuckers can do what you want with them, just questions after all.

I may not always take the advice, but if I’m asking for some, it is because I want to at least consider it, and explore the issue. But it has to be said, if it’s anything technical, I can just Google it, as no doubt I’d be told to do, anyway. :p

I also have recieved great advice from you, @Kardamom. Cooking recipes and pickled vegetable help, I remember in particular having been useful. :)

No, never a thought with me.

No, if I ask, I want a variety of opinions and ideas even if I have already formulated a tentative plan.

Yep. I only hear what I want to.

No. I ask because I want to learn what jellies have to say. I have gone into some questions knowing that someone would get offensive, or over the top preachy, etc. but as long as someone actually has something to add, I want them to chime in. I am disappointed not more people have contributed to my good cop bad cop thread, but I made a correct prediction that a particular anti authority jelly would delight in providing bad cop stories. (Thank you Legion, as they have been very colorful and informative. :-)
I have asked a question or two knowing certain jellies would take the opportunity to vent, and that is okay too. Just be aware, I may vent right back until the jugular is spurting in my mouth, ha ha!
Welcome all comers. Sometimes I learn stuff I never expected to.

ALL of the advice?

The only way to be certain that I won’t follow ANY advice among the multitude of answers is if I know in advance what those answers will be. A lot of questions here ostensibly requesting advice would be better categorized as soliciting opinions.

You might not take their advice, but I do like hearing their opinions on the question weather or not I agree with them.

Not on Fluther. But I’ve done this in real life. Asked a question because I felt like I should hear what my friend or whoever has to say, even though I’ve already made up my mind. I recognize it’s kind of a silly thing to do. But I’m not a jerk about it. I listen to them; I just know that it won’t change my mind.

Nope. That would just be a waste of time.
