How a Cough or Clearing of the Throat May Indicate Deception

Someone can cough or clear their throat because they have a cold or allergy. But sometimes a scratchy throat is due to psychological irritation. Nerve endings, including those in the throat, can fire when we are stressed. Our central nervous system is alerted that something is not right.

Liars can cough or clear their throat subconsciously when they lie, and sometimes we subconsciously, cough or clear our throats when we hear someone else lie.The symbolism is powerful. We hear someone lie or we know about a lie or secret and the topic of the lie is being discussed and we want to say the truth but, it catches in our throat. Our central nervous is responding to the dissonance. We have the truth inside but, it is blocked from coming out.

In order to distinguish whether someone's cough, throat cleanse is a response to a speaker’s lie note the timing, in this case, Mulvaney was not coughing and suddenly started coughing when Trump was asked about his tax returns. Again, Mulvaney might have had a throat irritation but, typically that would be indicated by him coughing throughout the interview, in this case, it was an isolated cough time with a question about Trump's tax returns. 

“Trump had been asked a question about his tax returns when someone off camera – identified as Mulvaney – reportedly begins coughing.”
