Higgs?

A press release from CERN cautiously announces the discovery of what may be the long-sought Higgs boson, with a spokesperson being quoted as saying, “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found.” [Read more…]

The problem of false positive results

My post on physics researchers searching for the Higgs particle needing to get the chance of statistical errors down to below the five-sigma level (or 0.000028%) generated some discussion on the problems that can arise (mainly the increased likelihood of false positive results) in other areas such as the social sciences where the threshold for acceptability is often as high as 5%.
