The Story Behind the Atlantic Salmon

What an interesting morning.  I started off by finding a post on a friend's Facebook page linking to this article by Jonah Lehrer in the New Yorker about the decline effect, from December 2010.  (For those of you who prefer to listen to your news, Radiolab did a short podcast called "Cosmic Habituation" summarizing the article here.)

Of course, I sent the New Yorker article along to my lab group, and my advisor (Aaron Clauset) responded with a link to an even better summary of p-values and the resulting bias in the scientific literature by Carnegie Mellon professor Cosma Shalizi, entitled "The Neutral Model of Inquiry (or, What is the Scientific Literature, Chopped Liver?)."

These collection of articles and posts summarize the related issues of false positives, stochastic effects resulting in positive results that may or may not be significant, and the file-drawer problem.

But really, I like my educational experiences to be thoroughly hilarious, as well.  So, ladies and gentlemen, I refer you to the second link in Prof. Shalizi's post, The Story Behind the Atlantic Salmon.  Because, really, if you can't derive significant scientific discoveries from dead ichthyological specimens purchased at a local grocery chain, how are any of us to make sense of this curious existence?  Enjoy.

Six Provocations for Big Data

danah boyd, author of the article
Today at the BioFrontiers Institute we had lunch with undergraduate students in the SMART program, who are doing STEM research for 10 weeks at the University of Colorado.  Our conversation over lunch about ethics, especially related to data sharing, reminded me of a great article about Big Data that I read last semester.  I'm going to post it here so that next time I'm interested in reading it, I don't have to dig quite so deeply into my gmail archive. :)  Without further ado: Six Provocations for Big Data.
