Conclusions
I presented a set of five Factors that, in my opinion, affect the communication to the general public when it comes to hard-science research. I tried to convey an analysis of the Factors, as well as possible mitigating options in order to improve the situation. I do realize that most of what I propose is hardly feasible, but I think that any food for thoughts is useful when discussing scientific dissemination.
To conclude, I personally think that one simple thing should be always remembered: provided no false promises are used, as long as you improve the human condition for the better it does not matter what you do. Some disciplines take minutes, some others take centuries. However, science is really the only tool we have to provide factual answers and working solutions on how the universe works, how to improve our lifestyle and health, how to mitigate adverse effects from cruel natural events. We are working for humanity, but humanity needs to know it properly.
