Reception
AllMusic reviewer Corey Apar praised the wordplay between Adam Lazzara and Fred Mascherino, selecting the song as an AllMusic reviewer's pick. Alternative Press reviewer Scott Heisel said that "Liar (It Takes One to Know One)" is "hands down, the best song on Louder Now." Gigwise was more negative, saying the song "sounds like a Hot Hot Heat b-side, and nothing like the Taking Back Sunday we have come to know and love."

Music video
The song's music video was directed by Tony Petrossian. The music video was released on September 29, 2006. The video shows the arm of a person hooked up to a lie detector test, as sketches within the polygraph show the band performing the song. At the end of the video, the figure hooked up to the machine is revealed to be frontman Adam Lazzara, while behind a one-way mirror stands the other band members, who appear to be the ones that gave him the test.
