Another thought inspired by [MENTION=6779310]aramis erak[/MENTION]'s posts, and relevant to the OP:
In the Wick games he mentions, the dice are rolled to allocate narrative power. (If I've understood correctly.)
You have.
BW is a bit more trad, but in some ways it resembles this: once the context of the check is framed, if the player succeeds on the roll his/her declared intent for his/her PC is achieved; if not, the GM's declared failure result is achieved. You could say that the negotiations around framing determine the two possible outcomes, and the check then determines whose narration - player's or GM's - becomes "actual" within the fiction.
In BW, no roll* is to be made without seeing both forks of the story. (In some rare cases, multiple forks - 3 or even 4 outcomes, each championed by participant's players, all hashed out before rolling, and high roller's version is what happens.)
* exception being in one of the extended resolutions: Fight, Range & Cover, or Duel of Wits.
One of the issues around knowledge checks which has come out over the course of the thread is a lack of clarity in framing over what the competing narrations/outcomes are that are being diced for.
The BW/MG method is for the player to state what he thinks should be there, the GM to set a difficulty (or another player oppose it with an alternate), everyone to agree to the terms, and then the dice get rolled.
So, the GM says, "There's something out there moving"
Joe says, "It's orcs"
GM says, "Perception, Ob 3, otherwise it's 3 trolls"
Joe rolls his 4 dice, and only gets 2 successes, and everyone else goes "Oh, S***!"
Fred pipes up, "At least, one of them is blind"
GM says, "Ob 7" (that's pretty near impossible.)
Fred looks at his Troll Lore of 3, Forks in "Tropical diseases" for another die, pops a persona for one more, and is loaned one each from Joe and Sam with their assorted lores. Amazingly, he gets 3 6's and 2 5's, pops a fate point, rerolls the 6's, and gets 2 more... that's 7 ...
GM says, "Ok, it's two trolls leading a blind third troll."
In HotBlooded....
GM: "Something is moving out there".
Joe: "Sounds like orks"
GM: "Wisdom rolls to define it"
Joe pulls together 6 dice, rolls 3.
Fred pulls 4 dice, rolls 2
Sam has 5 dice, rolls 2
GM pulls together 5 dice, rolls 4.
Joe rolled 9 - loses his 3 "wagers"
Fred rolls 10 - 2 wagers from unrolled dice
Sam rolls a 11, 3 wagers from unrolled dice.
GM rolls a 15. Has one wager. the others lose half their wagers, leaveing Fred 1 and Sam 1, GM 1, and Joe none.
GM starts, having earned the privilege of deciding it Joe was right. "No, it's not orks." Puts away the wager die, saying, "It's trolls"
Sam, next higher roller, says, "There's three of them"
Fred and Joe groan.
Fred says, "But one is blinded."
In D&D, typically:
GM: "SOmething is out there. Roll perception"
Joe: "I hope it's orcs." rolls, gets a 15.
Sam rolls, gets a 15, as well
Fred gets a 17 total.
GM: "It's three trolls!"
Fred: "but that's more than double lethal for us! Is maybe something wrong with one?"
GM (backpedalling, as he notes the CR): "Uh, yeah, sure... One's blinded."
