Left-handedness runs at about 10% of people, and minority status alone attracted suspicion. Latin sinister meant left and acquired its modern sense through omen-reading, where birds appearing on the left were unfavourable.

Why it stuck. A stable 10% minority guarantees the belief never dies out for lack of examples, and never becomes universal enough to be tested.

What people say

The left hand is unlucky, unclean, or receives rather than gives.

Left-handers were forcibly retrained in schools well into the 1970s. The superstition had physical consequences for millions of children.

Where it applies. Strongest where the left hand is reserved for hygiene — much of the Middle East, South Asia and West Africa.
