I'm developing a paper right now based upon some of my preliminary results, and I'm attending several conferences to present and get some feedback on my results from other experts in my field. A thought occurred to me that because my work is yet to be published, I there is a potential for others to steal my idea and publish before I get a chance.
I'm probably over-thinking this, and there is little chance of it actually happening. But I'm curious how frequently this happens in scientific domains. Do people go to conferences to steal ideas? If it does happen, how can I best prevent it from happening? Obviously, I want to share my ideas with the world, but I don't want to lose a chance to take an idea into fruition. What should/shouldn't I share about my research before it is published? Should I simply wait until my paper is accepted before I go on the conference circuit?
Update:
My field is computational science (not to be confused with computer science).
