Women are apparently sickly and cheap...

Erich wins half a cookie! The first sentence is correct, the other is false. There's nothing wrong with statistics in itself, but when people interpret them, that's when bad thing happens.

People usually forget blinding (placebo effect issue), proper randomisation techniques, or generalize the study. If the study doesn't explain how the blinding and randomization is done, then the study is unreliable - not because the statistics are wrong, but because data about the study is missing! Look for studies which are double-blinded, placebo-controlled with no drop-outs (or state how many drop-outs there are) and which is computer-randomized - if those things are possible.

Plastic surgeons who gave their patients pomegranate juice and pomegranates before and after surgery cannot show that pomegranates have a positive effect on people, neither in general or for people who have pomegranate juice before and after surgery. People who eat a lot of fruit and care more about their health would more likely drink pomegranate juice than someone who does not eat a lot of fruit, for instance.

Studies about how cells react to certain things (such as antioxidants) does not tell how the human body would react to more antioxidants, either. It just tells us that cells in an artificially created environment will react to X in some sort of way with a certain probability in some specific confidence-interval.

Just be aware of that when checking out studies, guys!
