This study is mind boggling. This is further proof that the psychological effects of abortion have not been examined thoroughly enough. This should be required reading for prospective mothers who think they may want to choose to abort.
Good grief. Where is the control group? What about 3 sigma anomalies? 237 families is not a large enough database! Did they do the same thing with upper income families?
In other words - not worth the paper it was written on.
