I think the report is a balanced look at the situation and a fair attempt at showing in what way the gap could be narrowed; but I have some reservation on the emphasis it gave to different aspects of the problem. The document also provides some interesting data on the beliefs of particle physicists and their involvement with outreach and communication activities.
One important part of the report concerns the strategic issue of "Building support among policy makers and opinion leaders". Here the authors identify several recommendations. I am not too interested in this particular issue though, so I won't comment on this part further. I would just like to say that to me the one of "educating your congressman" is a distracting goal. Much more important than that would be to create the conditions for a change of our society, such that the next generation of congressmen are chosen also on the basis of their scientific literacy rather than the other way round. I really think we should work at the roots of the problem rather than finding ourself in the emergency of fixing the top as well as we can.
The text contains the word "blog" twice and Twitter and Facebook are mentioned once. I believe this is a measure of the fact that those media are not considered very important to the cause by the authors of the study, which is contrary to my own belief (as is obvious by the fact that I have been blogging for eight years now...). In fact, I do believe that the combination of social media and outreach activities such as blogs and articles on popular science magazines available online is one very important tool for the capillary diffusion of scientific literacy and ideas in support of basic research to the general public.
In the part titled "Building public appreciation for particle physics", which is more interesting to me, the report focuses on distinguishing the audience in categories - "popular science enthusiasts", "everyday people", "parents", "science skeptics", and "critics of public funding of science", for the purpose of trying to tailor to the different targets the outreach means and the messages to convey. I believe that this may be a good schematization, but I fear it sounds a bit like micromanagement to me. Besides, no single person belongs to one and only one of those above categories.
I would have preferred to see more focus on the improvement of the way we reach people based on the ways we have to reach them - i.e. the media. If we conquer the media, we reach everybody. Television, newspapers, facebook. Those are the ways, like it or not. Television is also mentioned just once in the report, while I believe it should still be one of our main concerns. There is too little good science in TV programs, and we do too little to increase that; of course, the problem in that case is how to make science entertaining, and that is a tough one - but until we face that we are doomed to lose.
