Absolutely none whatsoever.
Edit: Confound these Lesswrongers, they drive me to research.
Anyways, to make a brief attempt using data from here, it seems that I was either overestimating p(oops|pill) or underestimating p(oops|condom). Of course, the hypothetical pragmatic pro-lifer really should be advocating for Dreaded_Anomaly's suggested methods as opposed to free pills.
Still, I give substantially more credence to the statement:
This intervention would cause a decrease in abortion.
(Note: I was not giving much credence to begin with.)
In line with the results of the poll here, a thread for discussing politics. Incidentally, folks, I think downvoting the option you disagree with in a poll is generally considered poor form.
1.) Top-level comments should introduce arguments; responses should be responses to those arguments.
2.) Upvote and downvote based on whether or not you find an argument convincing in the context in which it was raised. This means if it's a good argument against the argument it is responding to, not whether or not there's a good/obvious counterargument to it; if you have a good counterargument, raise it. If it's a convincing argument, and the counterargument is also convincing, upvote both. If both arguments are unconvincing, downvote both.
3.) A single argument per comment would be ideal; as MixedNuts points out here, it's otherwise hard to distinguish between one good and one bad argument, which makes the upvoting/downvoting difficult to evaluate.
4.) In general try to avoid color politics; try to discuss political issues, rather than political parties, wherever possible.
If anybody thinks the rules should be dropped here, now that we're no longer conducting a test - I already dropped the upvoting/downvoting limits I tried, unsuccessfully, to put in - let me know. The first rule is the only one I think is strictly necessary.
Debiasing attempt: If you haven't yet read Politics is the Mindkiller, you should.
