Freedom of research means that, as a researcher, you have the freedom to choose a research topic, define research issues, choose materials and methods to find the answers, and to present and discuss results and reasoning in public. As a matter of course, as mentioned under section 1, a contract restricts your freedom of research in relation to choosing a research topic, but it does not rerestrict your freedom to define issues, choose materials and methods, and present results. If, as a researcher, you are not able to vouch for these aspects, you should not engage in the project.
