I am amazed by Pat Swain's statements implying that unless a program of work
includes formal hypothesis testing, it's not even research. ("...I think
that pure survey of a property for species (making a list of all the species
of some taxonomic group) encountered isn't research...", "...some of the
projects that I rejected as not being research might well have been fundable
...")This appears to be defining the word research in a way I have never
seen or heard before. Does this mean that none of the scientific work that
was done before the rise of modern statistics was not research? Where the
people doing that work also not really scientists? And whatever happened to
library research?
