I am interested in this project and would love to get involved
if there is a place for me. I don't exactly fit the categories you
described but am extremely concerned about the issue of
communication of scientific information to the lay public.
I'm a pretty low-level freelance writer with a bimonthly
column in a magazine on dogs and my first sole-author book
(on dog training) in press.
Although I now work as a dog trainer I have a PhD in Physical
Chemistry plus post-doc and three years of college teaching.
Having read plenty of scientific articles and having been on
both sides of the peer review process I have the ability to
critically read scientific publications and to know, for example,
that a conclusion (the data support X) is meaningful only in
the context of the experimental design (is the result significant?
is it accurate?) and the scope (breadth) of the study, which
is often so miniscule there is no real-world application.
I tear my hair over the scientific ignorance of the general
public and the awfulness of what journalism transmits regarding
science, and would love to be part of an effort to improve
communication.
