Many people get away with chronically lying for many years. They start with false awards, and false resumes, and move on to false claims of credentials, false tax returns, and lying under oath. I personally know two people who claimed false Ph.D.'s in psychology. One was a practicing clinician. He went to prison. Some get away with it forever. And some see everything crash down. They lose their reputation, their house, their business, their families.
Here’s the thing – In this day of big data, you better be an excellent hacker if you want to go down this liar’s alley. Because some day you will annoy someone, or cheat someone, or jilt someone, and that person will get upset and do some digging. And once they find out things you have been lying about, they will report it to your employer, college, or even the IRS or the police. So, if you are going to cheat, make sure you are adept enough to hack into the relevant databases and change your data.
