In a previous blogpost , I criticised a recent paper claiming that playing action video games improved reading in dyslexics. In a series of comments below the blogpost, two of the authors, Andrea Facoetti and Simone Gori, have responded to my criticisms. I thank them for taking the trouble to spell out their views and giving readers the opportunity to see another point of view. I am, however, not persuaded by their arguments, which make two main points. First, that their study was not methodologically weak and so Current Biology was right to publish it, and second, that it is unfair, and indeed unethical, to criticise a scientific paper in a blog, rather than through the regular scientific channels. Regarding the study methodology, as noted above, the principal problem with the study by Franceschini et al was that it was underpowered, with just 10 participants per group.   The authors reply with an argument ad populum, i.e. many other studies have used equally small samples. This ...

 © cartoonstock.com So you’ve slaved away for weeks giving up any semblance of social or family life in order to put your best ideas on paper. The grant proposal disappears into the void for months during which your mental state oscillates between optimistic fantasies of the scientific glory that will result when your research is funded, and despair and anxiety at the prospect of rejection. And then it comes: the email of doom: “We regret that your application was not successful.” Sometimes just a bald statement, and sometimes embellished with reviewer comments and ratings that induce either rage or depression, depending on your personality type. There are three things worth noting at this point. First, rejection is the norm: success rates vary depending on the funding scheme, but it’s common to see funding rates around 20% or less. Second, resilience in the face of rejection is a hallmark of the successful scientist, at least as important as intelligence and motivation. Third, the...

Here’s a paradox: Most scientists would give their eye teeth to get a paper in a high impact journal, such as Nature, Science, or Proceedings of the National Academy of Sciences. Yet these journals have had a bad press lately, with claims that the papers they publish are more likely to be retracted than papers in journals with more moderate impact factors . It’s been suggested that this is because the high impact journals treat newsworthiness as an important criterion for accepting a paper. Newsworthiness is high when a finding is both of general interest and surprising, but surprising findings have a nasty habit of being wrong. A new slant on this topic was provided recently by a paper by Tressoldi et al (2013) , who compared the statistical standards of papers in high impact journals with those of three respectable but lower-impact journals. It’s often assumed that high impact journals have a very high rejection rate because they adopt particularly rigorous standards, but this appear...
