Well, it is not a surprise that scientists converge on a more singular idea. This is described in the Delphi method: https://www.youtube.com/watch?v=0ap77w8FKYM where we see how people's minds are changed as they attempt to reach a consensus.

But, we should remember that consensus on an answer doesn't actually mean it is the right answer. It can be gamed - eg if you only choose scientists with a particular background to respond in the consensus seeking process. The selection of those inputting into the process needs to be free and open. If not, and you select opinions from one group only, eg mechanical engineers, or bacterial bioligists, you will get a very specific answer that reflects the bias of those partaking in the process.
