Wingnut, socon, and sexophobe types are using a new study to claim that access to contraception does not reduce the abortion rate. In reality, the study does not support those people’s conclusions.
The study in question was published in the journal Contraception, and you can read the abstract here. (You can also read the abstract at the official journal website, but that requires cookies.) If you read the abstract, you’ll find the following passage (emphasis added):
CONCLUSIONS: The factors responsible for the increased rate of elective abortion need further investigation.
In other words, the study says that the reasons for the increase in the abortion rate are unknown. It expressly disclaims offering any explanation for it. This, along with the fact that correlation does not imply causation, shows that it is incorrect to use this study to claim that access to contraception increases or does not reduce the abortion rate.
Despite this study, other studies have shown that access to contraception reduces the abortion rate (cite, cite, cite). How could discrepancies between these studies be reconciled? I predict that the first study differs because of confounding factors or lurking variables.
