A highlight from Charles Murray's new book:
Data can bear on policy issues, but many of our opinions about policy are grounded on premises about the nature of human life and human society that are beyond the reach of data. Try to think of any new data that would change your position on abortion, the death penalty, legalization of marijuana, same-sex marriage or the inheritance tax. If you cannot, you are not necessarily being unreasonable.
David Frum counters:
As a matter of fact, if you announce that there can exist no possible information that might change your mind about abortion, the death penalty, marijuana, same-sex marriage, and the inheritance tax, then yes you are an unreasonable person—or anyway, an unreasoning one. I've changed my mind about same-sex marriage as experience has dispelled my fears of the harms from same-sex marriage. If somebody could prove to me that marijuana was harmless or that legalization would not lead to an increase in marijuana use, I'd change my mind about marijuana legalization. And so on through the list.
