Marco Bertamini & Marcus Munafo:

IN recent years, a trend has emerged in the behavioral sciences toward shorter and more rapidly published journal articles. These articles are often only a third the length of a standard paper, often describe only a single study and tend to include smaller data sets. Shorter formats are promoted by many journals, and limits on article length are stringent — in many cases as low as 2,000 words.
This shift is partly a result of the pressure that academics now feel to generate measurable output. According to the cold calculus of “publish or perish,” in which success is often gauged by counting citations, three short articles can be preferable to a single longer one.
But some researchers contend that the trend toward short articles is also better for science. Such “bite size” science, they argue, encourages results to be communicated faster, written more concisely and read by editors and researchers more easily, leading to a more lively exchange of ideas.
