Courier Mail: Smacking children ‘lowers their IQ’
After studying 800 toddlers aged between two and four over a four-year period, he found those who were subjected to smacking had an IQ five points lower than that of a child who wasn’t physically disciplined.
“The results of this research have major implications for the well-being of children across the globe,” he said.
“All parents want smart children. This research shows that avoiding smacking and correcting misbehaviour in other ways can help that.”
Children aged five to nine years who were smacked regularly had an IQ 2.8 points lower. Dr Straus said children who constantly faced physical punishment lived in fear and suffered stress, which was associated with poorer academic performance.
The study is by Murray Strauss, co-author of the Conflicts Tactics Scale (CTS) couples study that MRAs so like to misquote and misuse.  Strauss and his team have also produced a version of the CTS that looks specifically at parents and children.
Strauss appears to be one of those researchers who is very good at getting positive press for his work. It will be very interesting to read reviews from his peers regarding this research.
1. It’s worth noting again for this post that Strauss rejects the MRA claim that his work shows that women are just as violent as men (CTS results do show that based on self-reports, women are just as likely to assault their partners as men, but it also shows that women are far less likely to batter their partners than men – MRAs tend to gloss this crucial distinction (and implicitly support and justify responding to a slap or shove with a closed fist)).
