I'm of the understanding that it looks for a few specific keywords (like "best") in the title. Try writing a nonsense title with "best" in it and hit Tab, then go back and change "best" to "biggest".

I think that's how it determines it as well. Considering the warning is "the question you're asking appears subjective and is likely to be closed", I think it just scans the title for common subjective words (since Stack Overflow is meant for questions being answered and not discussions).

this appears more correct then my guess, but I still think the way I thought makes more sense(the system learns). Commented Jan 4, 2010 at 13:47
It looks at the matched questions for a high ratio of closed:not-closed.

the title "What's your question? Be clear about what what an agreeing and disagreeing answer would be." has 10 closed questions in the 25 listed, so by this theory the ratio is no higher then 10:25(closed:total). Commented Jan 4, 2010 at 5:21

"Be clear about what what an agreeing and answer would be." has a ratio of 8:25, and does not give the warning. Commented Jan 4, 2010 at 5:22
Not just that. It also looks for keywords like "you" For example,
How would you do something in somelanguage in the best possible manner
returns the alert
How would you do something in somelanguage
returns the alert; while
How to do something in somelanguage
does not return the alert
