Is being chosen by Joel Spolsky not enough of an endorsement for you?

So I've read the PP piece and your article, and I think your criticism is way off-base. The most technical part of your argument relies on a p-value being .057 vs .05, which is not…

I don't think advertising for jobs is a zero-sum game, especially if the matching algorithm is good enough to match employers and employees that had no knowledge of each other befo…

To be a little more clear about the diamond and circle... LASSO is a diamond because it represents the constraint that w_1 + w_2 Ridge is a circle because it represents the constra…

Does SSRN come with any guarantee of peer review or minimum quality threshold? The only downside with arXiv is that anything can be posted. It works fine as a paper-hosting service…

Totally agree; this is basically a text-book example of the "No True Scotsman" argument.

I think it's possible that its both a sickness and a boon. I fully agree with your point that the "fear of being a loser" does drive people to work harder, do better, etc. All of t…

Thanks for the suggestion. If you click on them, they'll pop out to the full size. Otherwise, I couldn't figure out how to get it to appear OK on both desktop and mobile (because I…

www.guessthekarma.com It's a simple game where I show you two images from Reddit (SFW of course) and ask you to guess which was more popular. I'm using the data from the site as pa…

You are right that the general problem is intractable; a lot of the advances in these match making algorithms come from better heuristics and computing power.

Here's a link to the slides that she used for the NBER talks. I've flipped through them and there seems to be some references to working papers (that Googling should be able to sur…

I agree with the original point. In my experience, there's such a strong selection process in who even tries to get tenure that most people simply can't turn off their drive becaus…

Thanks for the feedback (and the Watts' reference). Building a plugin is definitely an interesting idea; I hadn't thought of that before. I guess the problems would be three-fold. …

At the risk of plugging my own work, I did a follow-up to the (really awesome) Watt's experiment using data from reddit and Hacker News: http://arxiv.org/abs/1501.07860 The work is…

You might also be interested in Duncan Watts' book "Everything is Obvious", which explores this tendency we have to assume that observed success equates to some skill. Its a nice r…

I don't think the issue is whether ads should prompt them to lose weight, or they shouldn't. I think the crux of the issue is that we (humans) are ceding this judgment (which have …

Interesting comparison but, by my understanding, epsilon greedy and A/B testing do not solve the same problem. Epsilon greedy is a method for minimizing regret, that is the expecte…

To put this more bluntly: You should not do a phd in the sciences (in the US) if you are not getting paid. Its indicative that either A) the department has insufficient resources (…

For people who enjoyed this article, I highly recommend Duncan Watts' book "Everything is Obvious" [1]. Its basically the thesis of this article expanded out over the course of a b…
