It depends on how many domain experts (N) disagree with you and how much of an expert you are. If you're not an expert in the domain, you can forget about it. If you are, then the chance you should scrap the idea is proportional to N.

With technologies pushing the edge of research, N is typically very small, and being headstrong and willing to take risks and experiment is an essential skill. At some point, you alone are a large enough fraction of N that all of humanity is essentially depending on you to take the risk. If you don't then it might be a very long time until someone equally as capable will.
