The challenge element of Misogi requires a 50-50 probability of success, unlike typical endurance events where completion is generally expected.

“So 50-50 shot because today I think he's right here. He argues like even when we take on a challenge, we have to know we're going to complete it, right? It's like people don't run marathons and go, I don't know if I'm going to finish the marathon. They say, I don't know if I'm going to finish the marathon and sort of insert some arbitrary time.”

“rule number one is that it has to be really hard and they define that really hard by saying you have a true 50 chance of making it so nowadays we tend to take on challenges where we're like i'm gonna do this and if we think we can't what do we do we train for like months until we're like ninety percent confident we're going to make it”

“it has to be true 50 50 because now I think when people take on challenges especially when there's a physical element they pick things that they know they will finish that are within their capabilities”

“so enter musogi and this is this idea that once a year gonna go out into nature I'm gonna do something really hard some challenging tasks so there are only two rules of musogi rule number one is that it has to be really hard so he defines this by saying you have a 50 50 shot at finishing whatever it is the Smithsonian Tassie decided to take on it has to be true 50 50 because now I think when people take on challenges especially when there's a physical element they pick things that they know they will finish that are within their capabilities”
