Texas Sharpshooter Fallacy Definition Phone Case

The Texas Sharpshooter Fallacy describes a situation where someone collects or examines a large amount of data without deciding in advance exactly what they’re testing, then chooses a sample which provides evidence for their existing opinion. It’s based on a story where an inexperienced gunman fires indiscriminately at the side of a barn, and then draws a target around the largest cluster of bullet holes.
