Trust me, I'm lying

In 2004 a nationally representative, anonymous, household telephone survey was conducted to explore the distribution of privately owned firearms in the United States, as well as firearm acquisition, disposal, and storage in households with guns.

The demographic information that was collected includes respondents' sex, age, race, education level, household income, criminal arrest history, armed forces membership status, type of residential area (e.g., urban or rural), and political philosophy.

Other domains of the survey included past year firearm use, guns and youth, awareness of and opinions regarding state and federal firearm laws, depression and suicide and aggressive driving.

Analyzing the answers of combined questions, I detected 243 people whom answers not compatible between them. Where they lying? Do they follow a pattern? In our daily life we lie to avoid problems or please the people. This project relates our most common lies representing the results of the survey by comparing all the respondents with the potential liars group. Also I created a manual book with instructions of how to detect the liars.
