Making a career of reading body language

During court trials, most people focus on the lawyers, witnesses, defendants, and victims. In high-profile cases, however, attorneys often hire consultants who concentrate solely on the members of the jury. Working in the courtroom, jury consultants study the body language of the jurors and interpret their reactions to specific witnesses and pieces of evidence. Based on these skilled observations, the consultants try to determine which way the jury is leaning — which witnesses are winning favor and which evidence is most persuasive.
When you reenter the United States after a trip abroad, you usually have to fill out some forms declaring what items you are bringing into the country. You hand the form to an immigration official, who is trained to look at a traveler’s eyes when asking, “Do you have anything to declare?” What the eyes say is much more important than what the form says.
