They said they ate 8 times and got diarrhea 8 times, the only way to be sure it’s one of them is to eat at least once without those ingredients and not get diarrhea

They said they got diarrhea 8 times over 8 bowls, but they never said how many ingredients they used.

Assume nine ingredients: a, b, c, d, e, f, g, h, i

Bowl 1: a + b + c + d + e + f + g + h + i: Diarrhea Bowl 2: a: No diarrhea Bowl 3: b: No diarrhea Bowl 4: c: No diarrhea Bowl 5: d: No diarrhea Bowl 6: e: No diarrhea Bowl 7: f: No diarrhea Bowl 8: g: No diarrhea Bowl 9: The one the OP is referring to, which could have h, i, or h + i

That’s a perfectly feasible if disgusting way to have a bowl from a poke truck if you’re doing it solely for an experiment. And that’s just one setup; there are more convoluted ones you could do that have fewer ingredients but mixed together so your bowls aren’t just one combination. I just chose the counterexample that’s easiest to construct mathematically.

  Yeah that’s what I meant, 100% diarrhea means they eliminated nothing. Sorry I should have phrased that better.

    Oh, no, you phrased it fine; I read 8 bowls and 8 bouts multiple times and somehow still misinterpreted the experiment. It was only after I wrote down and submitted an example setup that I snapped out of my own illiteracy.

    If we’re taking them at their word (and not the silly joke it is) technically they could have removed 7 ingredients so far, with only 2 left, while still having diarrhea each time. In that context, say next time they try the dish with only 1 ingredient and the don’t have diarrhea, then they have the likely suspect. They could then try the dish with every ingredient except the suspected allergen to confirm it

    100% diarrhea means they eliminated nothing.
    
    I take exception to this phrasing, whenever i have 100% diarrhea I eliminate the the contents of my guts and a half roll of toilet paper at least.
