Indeed, but what I'm claiming that elementary detection of this kind of deception may be taught. I have a few colleagues who travel to Israel extremely frequently. If they say they are going to a conference in Tel Aviv and have a poster in a rolled-up tube, the agent asks them what they will be doing. They say so, and they have each been asked a question about their research, relatively specific, something that was obviously studied / researched, and relatively in depth. It would be entirely possible to instruct an intelligent person to "detect" major deception regarding the purpose of travel.

I could instruct an agent to memorize 5 questions that every doctor could answer, but a layman would not know what I was even talking about. That is true I'm sure in every profession. Every airline pilot could tell you what "ATIS" is but most passengers could not.

This is NOT the same as the "voodoo" nonsense at our airports. Our country is fundamentally different from Israel.

My colleagues each looked really surprised the first time they were interviewed, and of course answered the questions well and were sent on their way.

If somebody says, "I'm going to Israel to work in xxxxxx field, or I'm from xxxx area, or I'm going to visit xxxxx," interviewing agents are prepared to ensure that the person isn't poorly bluffing. This is useful *for their purposes.* It is NOT useful for ours.
