Bias against left-handed people

Bias against left-handed people is discrimination, conscious or not, against people who are left-hand dominant. Approximately 10% of the world's population is left-handed. Yet many common tools are designed solely for use by right-handed people, making them difficult, painful, or unsafe for left-handed people to use. These range from simple objects such as scissors to dangerous machinery such as power saws. Beyond such neglect, however, left-handed people have frequently been subjected to deliberate discrimination and disparagement. In many societies, they are considered unlucky or even malicious by the right-handed majority. Many languages use references to left-handedness to convey awkwardness, dishonesty, stupidity, or other undesirable qualities. Even in relatively "modern" societies, left-handed people historically have been—and in some places still are—forced from childhood to use their right hands for tasks which they would naturally perform with the left, such as eating and writing.
