My post about how to distinguish real science from fake science generated some interesting comments, especially over my assertion that we have not as yet been able to come up with an unambiguous way to distinguish science from non-science, and it prompted me to post a follow-up to try and clarify it.

I am in Washington DC and today is a nice sunny day. This city was largely spared as Hurricane Sandy seems to have gone slightly north of here, hitting severely New Jersey and New York. [Read more…]

Peer review is an important part of the academic publication process. All scholarly articles undergo peer review from at least one other person familiar with the field (plus an editor of the journal), although two is the more common number of reviewers, and sometimes may be more if there is disagreement amongst the reviewers or a strong appeal from the author of a rejected paper.

Given the rapidly proliferating number of polls and models predicting the election, the interesting question to be answered after the election is which did the best job. Poll aggregator Sam Wang says that a good prediction should: [Read more…]
