Experiment/Poundstone: is invalid if it was run sloppy - the results can be true or false - error: E.g. expectation experiment (assuming that the experimenter unconsciously determined the result ): a) if the results are true, you cannot trust the test persons - b) if the results are wrong, there is no prejudice effect - c) if the study is valid, then the result is true, and the investigation is invalid - ... Poundstone: the investigation is not valid in any case.
