The truth is ... we are all liars.

Scientists say that by the age of four we have all learned to lie. We lie to protect ourselves and others. We lie to protect others' feelings, and to get what we want and need. Most of us fib in one of every four conversations that last more than ten minutes. One study showed that university students lie to their mothers fifty percent of the time. We lie in one-third of our conversations with our romantic partners, and we tell the most serious lies to the people we care about the most. (read more 'truth' about lies)

From the common little white lie to promises made by those governing us, scientists tell us that lying is part of our daily lives. Lying is integral to our survival, and the ability to lie is fundamental to how far we succeed in our work, romance, and everyday life. Featuring the latest science, psychology, and technology, this surprising documentary also exposes our greatest weakness: our ability to sort the lies from the truth remains in the dark ages.

The very unique relationship politicians have with the truth is also examined by The Truth About Liars using the Watergate crisis, the Clinton-Lewinsky scandal and the Iraq war as examples. It discusses how society has now come to not only often expect the bending of the truth from those in a position of power, but also the degree to which we now accept it.

The Truth About Liars concludes with one essential choice we all face - do we want to live a trusting life and risk being misled, or be suspicious and risk disbelieving those who are telling the truth?
