The way this study is reported is quite typical of the way the media reports things. This is not original research, it is a survey of 300 other studies by the looks of it. Which begs so many questions: how did they choose these 300 studies, on what basis, which studies did they exclude from the research, how did they collate the data so that the sample base of each study was compatible, the methodology was compatible, the social and economic variables were factored in, the results were compatible... it's all just rubbish! I personally never believe any headline that starts "new study shows that..." because you can guarantee that a) it is probably not a new study, it's a re-hash of several old studies, with a sample base of eight students, and b) the new study shows no such thing. Think I lost my faith in "research" when I read about the research that was done in Sweden on drinking in pregnancy, showing that it was very dangerous and women shouldn't do it. It turned out that the sample base was 9 (no, not 900, not 90, 9!) Swedish women, all of whom had a long history of alcoholism and drank several bottles of gin/ wine etc., throughout their pregnancy. And from that study it was extrapolated that pregnant women would have babies with Foetal Alcohol Syndrome if they had so much as a sip of dry sherry at Christmas. It's all Bo*cks! Like most of the research which the media picks up on and reports in the most irresponsible way imaginable. But what really annoys me is when health professionals, government officials etc., give this sort of rubbish house room. The fact is, none of us really know what effect smacking has - I agree with what most people have said, that context is everything - but "studies" like this, are not going to give us any further enlightenment. Or at least, the way the studies are reported are not - because to be fair, academics are not responsible for how the media report their work.
