Whilst the title is true, I don't think that it adds much as, for most people, the authority of a researcher is probably as good as it gets. Even other researchers are probably not able to reliably tell who is or is not a good strategic thinker, so, for a layperson, there is no realistic alternative than to take the researcher seriously.
(IMHO a good proxy for strategic thinking is the ability to clearly communicate to a lay audience. )
