I tend to be pretty dismal about that, frankly. It may be good 'medicine', to get people away from fetishizing p-values.  However, it struck me as a licensing of sloppy experimental/statistical practice, rather than as a way of improving it.  I would frankly be happier if they said either (a) "be very statistically persuasive, but we don't care exactly how", or (b) "we don't really care if your results are true/replicable".  We'll see, of course, but I worry that that journal will become a journal of "p=0.06? Can't publish in your regular journal, but you like your theory?  No problem!".

I get really annoyed sometimes at the way information is presented in the world. For instance, Ipsos Mori just published a poll which shows that perception of number is psychophysically scaled, did some very wrong math on it, and dressed it up as an "index of ignorance".

The ignorance of the Ipsos Mori Ignorance Index. A number of news outlets and otherwise sophisticated blogs are reporting on the Ipsos Mori "Index of Ignorance", where the polling group purports to gather data about how people misunderstand and 'overestimate' proportions of various values in ...
