Gee, I just hate to see all this sweetness and light, everybody (well, almost everybody) agreeing how spanking is right. Well, it is time for me to set the cat among the pigeons.
JLM, quoting a study from a Christian College? Be ashamed. What conclusion do you think a researcher at a Christian college is going to come to? Suppose she had come to the conclusion that spanking is harmful to the children (as many studies have shown), do you think she would have kept her job?
Indeed, somebody made this precisely same point. To quote from your link:
“Grant Wilson, president of the Canadian Children's Rights Council, suggested that the study's results may have been influenced by Calvin College's Christian affiliation, adding that some religious groups have opposed abolition of corporal punishment.”
Doesn’t the Bible say ‘spare the rod, spoil the child’? What other conclusion would you expect a Christian college to come up with? Indeed, a professor at a Christian college concluding that spanking is beneficial is tantamount to a study financed by the tobacco lobby coming to the conclusion that smoking is good for you. Give me a break!
Besides, the study is probably seriously flawed scientifically. Again, to quote your link
“However this latest research, which Prof. Gunnoe admitted was previously rejected by two professional journals, including the Journal of Family Psychology, contradicts other findings that spanking is counterproductive.”
The paper was rejected by two scientific journals. The article doesn’t say that it had been published by any scientific journal, so it is quite possible that no scientific journal would publish it.
In summary this is a study by a special interest group (a Christian College) which is trying to promote their own theology (spare the rod, spoil the child). It is no different than a study sponsored by tobacco industry telling us that smoking isn’t harmful to you, or a company manufacturing candy bars, sweets, coming up with a diet which includes eating two of their candy bars every day (this actually happened).
In other word, the study is worth nothing.
