There are 2 different approaches for each sexes.

the eyes deviate slightly to the left indicating the Male is accessing the creative part of the brain

heartrate elevates in an attempt to support the strain of the creative effort

pupils constrict slightly instinctively in preparation for flight/fight response

sweatpores extend slightly to reduce heat and give the appearance of being cool CONCLUSION If all these match then the subject has a high probability of having lied in response to the question

For Females OBSERVATIONS

is she breathing?

is her mouth open and words are coming out of them? CONCLUSION she’s lying

Edit: sorry this came from a bad place. Just had an 8 year relationship break
