Since mostly one's research plan that are usually further work of one's current research are different from the future research project in the position that he is applying for, that is because everyone's research is different from others', I think putting the research plan in a research statement may reduce the chance of getting an interview in job application.

Of course, one can write a research plan for each research position, but it will take a lot of time for one to write different research plans for all the position he applies for, as some people need to apply for hundreds of positions in order to get one job.

So I am wondering if one should avoid putting his research plan in his research statement when applying for a job.
