Falsification is a prominent aspect in Frank Gallagher’s life; he is a compulsive liar. Frank is constantly making up stories trying to make himself seem like a better person than he actually is. He tells straight-up lies to get money, get out of work, and/or to use people. A good example of falsification is every time Frank tries to get disability payment from the government when he pretends to get hurt at work; he makes up a story about how he got 'injured', and he gets compensation for it. Frank is a professional deceiver because (as explained earlier) he lacks empathy and he doesn't care what people think of him.
