Formerly known as "Voodoo correlations" before the editor made him tone
it down.

This is awesome, and it reminds me of a debate at the upcoming Society for
Experimental Social Psychology:
Puzzlingly High Correlations in Cognitive/Affective Neuroscience
Matthew Lieberman, University of California at Los Angeles vs. Piotr
Winkielman, University of California, San Diego, with David Kenny as
moderator
The debate is organized around a paper that just came out in Current Directions in Psychological Science (Piotr Winkielman is one of the authors), which argues that the methods of a great many fMRI studies lead to spurious correlations (the original title of the paper was Voodoo Correlations in Cognitive/Affective Neuroscience) because researchers selectively define the brain regions of interest after looking at the data.

Subject: [tips] Dead salmon detects human emotion
Remarkable new experiment, a fMRI study by Bennett et al
reported at the 15th annual meeting of the Organization for
Brain Mapping in June this year in San Francisco.

>From the Methods section of the abstract:
Subject: One mature Atlantic Salmon (Salmo salar) participated
in the fMR study. The salmon was...not alive at the time of
scanning.
Task: The task administered to the salmon involved completing
an open-ended mentalizing task. The salmon was shown a
series of photographs depicting human individuals in social
situations with a specified emotional valence. The salmon was
asked to determine what emotion the individual in the photo
must have been experiencing.
