  2. What do you think a filter/filtering something does?

    Religion is being a good theoretician?


    You know the old joke?
    A quack doctor (in the then Wild West) travelling from
    town to town treated a farmer for fever: "Eat sauerkraut".
    The farmer recovers. The quack doctor writes in his little
    black book: "Sauerkraut helps against fever."

    Another town, soon after. The smith has fever. So,
    consulting his little black book, he orders him to eat
    sauerkraut. The smith dies, however.

    The quack doctor corrects the entry in his little black
    book: "Sauerkraut helps against fever only for farmers."

    Can you spot the model and assumption that led the quack doctor
    to the "corrected" entry?

    So basically Ehrenhaft was wrong.

    No, picking your data to support your model is behaving like a religious
    zealot.
    As an experimentalist I'm interested only in the data, not the model.
    His theory was wrong, his experiments though were simply imprecise.

    Science doesn't work by isolated experiment. We had two experimenters,
    one of whom fudged the data and the other of whom was sloppy, so they
    got different results. Later experimenters did not fudge the data and
    were not sloppy and found that their results were similar to those
    obtained by the one who did fudge. At that point his model was
    confirmed. If instead of fudging his data he fixed his experiment then
    he would not have had to fudge.
