I know people always want to discuss the merits of the memo -- whether he was right, wrong, or somewhere in between -- but I'd like to have a meta-discussion.
I believe the memo is irrelevant not because of its content, but rather because it's embarrassingly reductive. In my opinion, anyone that takes it seriously validates Damore's ultra-reductive approach to social policy -- and this is, I think, unequivocally wrong.
I recently wrote a blog post, Confusing Math with Morality[1], in which I touch on a similar subject matter. The problem with smart non-liberal-science people is that they think they are just that -- smart -- when, in fact, the emotional intelligence of STEM majors is barely average[2][3]. Now this doesn't mean that this disqualifies math-y people from having opinions on social policy, but it certainly means I value their opinions much less. In the market of ideas, theirs are simply not worth a whole lot.
For example, you may think you have an educated opinion on abortion, or euthanasia, or nuclear proliferation. But the reality is that you don't. And I've been called an elitist before, but until you take a few semesters on abortion[4] and read some court opinions, your views are simply not worth much of a damn.
And, as far as Damore is concerned, it's a very similar scenario. He's trying to argue for or against some kind of social policy, but he simply has no idea what he's talking about. I doubt he's even heard of Bakke v. UC Regents, never-mind read Betty Friedan's Feminine Mystique. Knowing about these is very important in the context of gender/race/etc. policies. My point is only that strong, sweeping opinions and viewpoints need to be properly contextualized. There are, of course, good arguments on both sides. But Damore makes none of them -- or even if he does, it's merely accidental to his "spray and pray" strategy.
And to be frank, I see this at work (and saw this at school) all the time. I've always tried to be broad in my education (both formal and otherwise) -- my grandmother was in charge of a library and I couldn't live without books. If you talk to a programmer and ask them what's the last book that they read, they'll probably mention something programming-related. If you ask them what news they read, they'll probably say slashdot. I had a co-worker recently question why I read fiction -- after all, we can expense any programming book we set our sights on. And don't think I'm ragging on programming books, I even wrote one! My point is only about the type of person attracted to this type of work -- and perhaps how STEM degrees have failed us. It doesn't seem like we are educating a generation of Isaac Newtons, but rather an army of regurgitating robots.
Damore is intellectually lazy in a sea of intellectual laziness. His views might be wrong or might be right, but his intellectual sloth is unforgivable.
