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 a good one. No one seriously believes that .05 is magi

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 before. If you are able to reduce those search frictions, y

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 <= 1. The region of (w_1,w_2) that satisfy that inequality is a square. Ridge is a circle because it represe

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 but is terrible as a "social proof that my paper is OK

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 that has (generally) positive effects (well, a

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"m not really a web developer).

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 part of my research into the dynamics on internet po

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 surface): https://onedrive.live.com/?

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 because its so fundamentally a part of them. Do they cha

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. First, I don't know how to do that :-). Secon

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 isn't complete yet (always mo

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 read.

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 political and societal ramifications) to the ad ma

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 expected loss you occur from choosing options that are sub-opt

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 (bad situation) or B) they really don't want you as a gr

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 book with a lot of interesting examples and le

Completely agree; learning to cook shouldn't be about cooking different recipes, it should be about generalizing the lessons from each one. That said, I think an effective way to learn it is just to try cooking a million different thin

I take some issue with the idea that we can simply just rely on another equilibrium refinement and say "no big deal". It seems a bit silly to observe some behavior in a game and say "See that's a Nash Equilibrium, so gam

These are interesting examples of using game theory to model certain situations but none of these examples show that game theory "tells us" something about the world. In broad strokes, game theory claims to have a descriptive mode

The islanders don't know that there are only blue and brown eyes. For all they know, their eye color could be green, red, etc. Hence, the logic only applies for the blue-eyed people.

Have you looked at number of comments instead of number of submissions? That would seem to be a better estimator of user growth. Honestly, I don't think that estimating number of submissions is a very good metric for the growth of Redd
