Link of the day: Looks, 1/f distribution, myth of meritocracy

First, an old link from months ago that I forgot to post: Your looks and your inbox. OK Cupid, an online dating service, does cool statistical analyses of how your profile affects response rate. One idea to take away is that women are very harsh on men's looks. Ouch.

One of the key ideas in my research is quantum noise. So it's neat to find an article claiming that modern movies have a cut frequency that follows a 1/f distribution.

Finally, via Cal Newport and a few links, I enjoyed the following New York Magazine article on why kindergarten admissions tests are worthless. The single most interesting takeaway message is how unreliable intelligence tests are for 4 year-olds.
I wrote to [University of Iowa psychologist David] Lohman and asked what percentage of 4-year-olds who scored 130 or above would do so again as 17-year-olds. He answered with a careful regression analysis: about 25 percent.

  1. As I see you are mentioning statistical research: I have put one of the most comprehensive link lists for hundreds of thousands of statistical sources and indicators on my blog: Statistics Reference List. And what I find most fascinating is how data can be visualised nowadays with the graphical computing power of modern PCs, as in many of the dozens of examples in these Data Visualisation References. If you miss anything that I might be able to find for you or if you yourself want to share a resource, please leave a comment.
