As I've said before, it's not a matter of proving if something exists or doesn't exist. With clutch, there is overwhelming evidence that suggests that clutch doesn't exist. I have not seen any evidence that is statistically significant that suggests that clutch exists. Therefore, my opinion goes with the data. It is an opinion based on data, not on my bias. In fact, this particular opinion goes against what my biases would be.
With the idea of comfort in the line up, there is no statistically significant evidence either way, for or against it. Therefore, I choose to believe it exists. I could have just as easily chosen to believe that it doesn't exist and asked you to prove that it does. Is this opinion based on my bias? Okay, I'll give you that. But it's not a bias that goes against any evidence.
In short, there are numbers to support one opinion but there are no numbers to support the other. That's the difference in what you are viewing as inconsistencies or bias.
