CORE DEFINITION

The Texas sharpshooter fallacy is the statistical fallacy of inferring meaning from what is essentially a random distribution of data points. It is the philosophical or rhetorical application of the multiple comparisons problem (also known as data dredging or p-hacking in statistics) and apophenia (in cognitive psychology). It is related to the clustering illusion, which is the tendency in human cognition to see patterns in random data.

The sharpshooter first fires at a barn wall, creating a cluster of bullet holes, then draws a target around the densest cluster, claiming 'Look how accurate I am.' This metaphor illustrates the fallacy of first having data and then selecting a pattern, ignoring multiple comparisons, and treating random clustering as a significant pattern.
