I wouldn't dream of asserting something like this. There are too many factors in any form of research producing too many unknowns to give a definitive "this is good" or "this is bad" stamp on ANYTHING.
I work in market research, and just about the smartest client I ever encountered was one who did research on styles and patterns of children's clothing. What he said that stuck with me most was that he has his designers come to him with all sorts of designs and he's careful not to critique them too harshly on any of them. His reasoning was that, in the surveys done to mass quantities of people, sure the yellow onesie with the orange giraffe was only liked by 5% of the people asked - but if he can just know the right number of yellow onesies with orange giraffes to produce he can still make a sale - and in fact, he might be able to ensure that his entire stock gets moved into revenue. Rather than making nothing but the blue striped onesies with the cutesy dog that 95% of the people surveyed liked and not sell a whole 5% or more of his entire inventory.
Point being, it's not about definitive good or bad. It's about knowing how to apply the informortion you have - and when to trust yourself vs. the survey/study telling you that something is "bad".
Well said, imo, and ya sorta stole my thunder-- OK, maybe it's only a wimper in my case.
I was going to use this true analogy: My wife, who's 68 (don't tell her I told you, OK?) is on hormone (estrogen) therapy because she gets regular (several times a day) nasty hot-flashes if she doesn't. But the studies show that she increases her risk of getting cancer by about 1-2%. So, she had to make a decision, and she chose to take it because not taking it would make her miserable-- and me too!
So, yes, statistically there is a higher risk taking the estrogen, and there's also one for "spanking" children as the study pointed out. Therefore, I don't refute the research, but I do have a lot of experience and observations that I can go on over my 71 years of life.
Nor is how we may "spank", or how often we may "spank", going to be uniform across the board. Certainly we can agree that beating a child is a terrible approach, and certainly we can agree that discussing the problem with the child is preferable over "spanking". But what if trying to talk rationally to a two-year old actually causes more problems than it solves, and that can easily be the case at times. Plus, there are other factors involved as well, so let me give an example of that.
When our oldest daughter was about two, and we were over my in-law's house, she misbehaved, I gave her one swat on her bottom, she ran around the table crying, jumped up on my lap, and cried while I comforted her. My mother-in-law saw this and was mystified why should would pick her up and console her. My wife explained (my mother-in-law didn't speak English) that just because our daughter did something wrong that this doesn't mean we don't love her, plus by picking her up and consoling her we also send the message that all is forgiven. In a very short time, she was again having fun playing with something else. This whole process took no more than about 5 minutes from beginning to end.
So, to me, it was sometimes better to make the point (a swat), move on, and let the child know you still care, love them, and have forgiven her/him.
