it does seem to make sense - levitt pulls out the statistical data and certainly shows correlations between factors like the $25k bonus and "no child left behind" to the rate of teacher cheating, and the abortion theory is surprisingly well-argued. it's hard to believe...but far stranger things have happened. i pay it as a very probable cause.

I have not finished reading this yet, but I am fascinated by it. It is always so cool to take a different perspective and look at things that way. You can come up with different ideas this way, and who knows what is correct. It's really quite a book.
