Beating the Polygraph

Lying lips are abomination to the LORD: but they that deal truly are his delight. Proverbs 12:22

There is a good reason that polygraph tests are inadmissible in court – they are unreliable. A person who is subjected to a polygraph test is hooked up to a blood pressure monitor and other detectors that register changes in blood pressure, body moisture, breathing rate, and other small changes often undetectable to the human eye. The polygrapher (administrator of the test) begins the test by asking control questions to get a baseline against which to measure all the other responses. Control questions are things like, “What is your name?” or “What year is it?” The way to “beat” a polygraph is to cause your baselines to register at unrealistic levels. For instance, biting your tongue causes pain that causes your blood pressure to rise. If your blood pressure is abnormally spiked during the “easy” questions, then it would not be viewed as spiking during the difficult ones. There are many other “tricks” that can be employed to cause a polygraph to be unreliable. The reason law enforcement uses polygraph testing, even though it is inadmissible in court, is most people are unable to fool the polygrapher, and the test results let detectives know if they are on the right track in apprehending the criminal or not.

However, there is one polygraph test that can never be beaten – God’s. Lying may be able to fool someone in law enforcement, but God knows whether everything you say is the truth or not. The Bible clearly says that God not only hears every word we say, but that He also knows our thoughts. That certainly steps far outside the realm of a polygraph test. Many people fall into a habit of “stretching the truth.” It is easy to do because they don’t want to look bad by admitting their mistake or wrongdoing. They are often surprised by the fact that a little lie got them “off the hook,” and, before long, telling a lie to escape punishment has become second nature to them. That is a dangerous way to live.

Since God knows the truth or falsehood in everything you say, He can reveal those things to the world. One day, those lies will come back to hurt you as everything comes crashing down. Your reputation will be stained, your credibility will be questioned, and your honesty will be doubted by all. Lying is an abomination to God, and therefore, He cannot let it go unpunished. There may be ways to beat a polygraph, but God will never be fooled. Determine that you will be one who will always tell the truth.
