Look for scattered eye movement , force emotions and exaggerated gestures , different answer to the same question , deflecting the question and over reaction . One good tip is to look at people ' s shoes . Are they boot or shoes ? What kind of boots or shoes are they ? Are they a trendy brand or simply functional ? Are they new or old ? Clean or dirty , cared for or wornout ? Do they go with the outfit ? When new , were they expensive or cheap ? Are the shoes the best they could afford or all they wanted to spend ? Finally , just trust your gut . Take in the information and listen to what your instincts tell you , they ' re mostly right .
