Science and research is open knowledge. We should always share our knowledge with each other. However in current competitive world, scooping research is very common (specially in bioinformatics, methodology and medicinal sciences where research has immediate applications). This has further downstream effects like less chance of getting published in good journal, loss of novelty etc. I was wondering what kind of information generally people share openly versus hide. I know this will depend on kind of research you and your rivals are doing but still is there any commonality ?
To be more specific, I am looking for research in computational biology. Let's say I want to present a poster in a conference where my rival group (working on similar topic) is also presenting. Now how much information about my current research I should present?
