Answer
Some flexibility in relation to the degree of specification and granularity of consent is allowed in the context of scientific research. When collecting personal data, researchers might not be able to fully identify the purposes for processing. In those cases they can ask individuals to give consent for certain areas of scientific research or parts of research projects. In any case, consent must keep its core elements, that is to say it must be freely given, informed, sought via clear affirmative action and specific to the extent allowed by the research in question. Researchers must make sure they also comply with the ethical and methodological standards required in their field.
