More and more political campaigns are apparently trying to "read" voters' minds.

Technologies like facial coding, biofeedback and brain imaging, which have long been used by companies, are now growing in popularity on the campaign trail, according to The New York Times.

Campaign records show that the campaigns of presidents and prime ministers on at least three continents have hired science consultants to scan voters’ brains, bodies and faces, with the aim of improving their emotional resonance with the electorate.

One "neuromarketing firm" says it has worked for a Hillary Clinton presidential campaign, a claim Clinton campaign’s chief strategist declined to discuss. Additionally, John Weaver, who was part of several Republican presidential campaigns said that he had used "neuroscientific tools" in the past.

Fox Business Network's Kennedy asserted on "Shepard Smith Reporting" that this is largely junk science.

"Although you may be able to use biofeedback or facial coding to tell how someone feels in the moment, the point is there may be no cause and effect," Kennedy said. "And what good are politicians who are fickly going to change their positions based on how a group of people might react seeing a billboard?"

She argued that one doesn't need to be a neuroscientist to understand that voters just want to know if a candidate's policies will make their lives better.
