If you have an interest in sexually transmitted infections, and who doesn't, you must download this bizarre paper.

It says that:

1) there is no evidence that STI control decreases HIV incidence,
2) that there is no evidence that it does not, and
3) that we will never know.

4) And then it suggests we use STI control to decrease HIV incidence anyway.

I agree with the first three but not the fourth.
