It wasn't and I think that's the point. Essentially soma was hard to distinguish from tap water, which OP had said tasted chlorinated, given that soma was suppo

So the difference between soma and bottled should be obvious (or there is some other factor in play), but it's clearly not. Obviously taste is not commutative, but there's something fishy here regardless.

  gp is right, there was 8/23 wrong classifications of "Bottled vs Soma" vs. 10/23 wrong classifications of "Tap vs Soma" In Figure 6 , the author shows there's no statistically significant difference between "Bottled vs Soma" So like he wrote : > Soma filtered water performed the worst, having a taste statistically indistinguishable from tap water I could write using the same data: Soma filtered water performed the best, having a taste statistically indistinguishable from bottled water
