This is a question that makes its round in the scientific community quite often. To answer it though, it is important to look at the different fields of science and they're progress and research in this world. In physics, the major companies like Nasa and CERN have each released all their papers on research they have done to the public. Was this a good decision? Probably. Releasing scientific knowledge to the world can awaken endless amount of curiosity and possible lead to people pursuing a science. Not only this, it gives the population an awareness of what is happening both on the earth and in the vast emptiness of space.
However, there are two main reasons as to why most secret science projects are kept secret in the first place. The first is the never ending competition between firms to see "who's the first". The second is the ethical limitations. To progress in the field of science, especially biology, one must experiment. The one catch in this though, is that in biology, one needs living subjects. Experimenting on living subjects can be a very sensitive subjects, because the grey zone between moral and immoral is fairly large meaning there will be too many people with mixed opinions.
Fields with little ethical implications like physics and possibly chemistry, should be open to the public due to the little problems it would have with everyone. Releasing this information could also help decrease false ideologies and therefore help increase more knowledge amongst the people. On the other hand, studies with strong ethical implications should be kept away from the public, until final results with as few as possible ethical implications are found.
